Astrobatics/Missions

Missions will get slightly harder as the player progresses, most missions have an intermediate boss, which is a boss that appears in the middle of the mission, all missions here will always have predictable pacing no matter how many restarts one will do, only the position of power-ups can change and this may delay your firepower upgrade progression slightly, but this shouldn't be much of an issue.

Due to missions having the same constant "scrolling" speed, using minute markers to help indicate important sections of missions will work but only if you do know how many minutes you've been in the said mission, using a timer will help, start it immediately when the mission begins then pause on the minute mark mentioned, minute marks on maximum firepower could vary depending on how you are catching upgrades.

Most bosses have parts that can be destroyed for extra score and to reduce their overall firepower, while they do not contribute to the total HP of the boss, these extra parts may still have to be destroyed to make a certain boss more manageable to beat.

Mission 1: Deadly Clutches
The introductory mission in this game, up to at least 6 enemies will exist here and this mission isn't too difficult, but for newbies the boss battle may catch them by surprise so it may take at least a retry or two but this shouldn't be too hard, this mission provides 1 extra life within the 5:20 mark, nothing is worth mentioning here too much as most enemies you'll face are basic, around 1:55 mark you should've been able to obtain all upgrades, within 4:30 mark you should've been able to maximize the firepower of your weapon which happens after the intermediate boss, some enemies here could appear from behind so this mission will also teach you how to use the Rear cannon, Lasers and the 2 other extra weapons will not be available here.

Boss

 * Intermediate boss - The boss in this mission will fire 8 bullets in 8 directions with moderate firing speed, the boss will also fire a laser for 2 seconds then it will release flames for 2 - 3 times before firing lasers again, its metallic mouth can be destroyed for extra score, do not get in the center of the boss as its laser hits pretty hard, and don't underestimate it as well.
 * Final boss - The boss you fought earlier will now come in twos, the strategy here to be able to survive is to stay in the middle and attempt to get free hits using your spread shots, you can try lowering down a little to be able to hit the lower boss with your primary cannon and destroy it first, if this is what you did and the lower boss is destroyed, you can now go all the way to the upper boss and fire it until it is destroyed, make sure you won't get hit with its laser.

Mission 2: Heavy Barriers
This is the only mission so far that contains barriers, Lasers will shoot through barriers along with Super-shot which is useful for AOE barrier destruction, but the barriers themselves shouldn't be hard enough to destroy with your normal shots as long as its adequately upgraded, there should be at least 6 - 7 types of enemies in here, turrets will be placed on top of destructible barriers, weaker enemies could also appear and shoot you at the back of your ship so you have to be really careful here, the mission contains 1 extra life but its hidden within a barrier, this barrier is found at the very top of the screen within 4:00 mark, this mission introduces a slight difficulty spike or moderate spike for newer players as the barriers limit ship movement, some can be destroyed while some are indestructible, indestructible barriers are larger and dark-colored, some has 3 blinking reds in its left side facing your ship, these lights can be destroyed if you fire at it directly with a maximized main cannon or Super shot, some destructible barriers are hidden within indestructible ones and if you are really looking for some extra score, Super-shot, Laser, Spread shots (to some extent), and Guard bots (to some extent) will reach and destroy them for you, due to immense amounts of Weapon power upgrades this mission will give you, you will immediately reach maximum cannon firepower within 2:05 mark but this doesn't include the rocket turrets yet, you should be able to get 2 Rocket turrets as well within the 2:55 mark, the mission will also constantly give you Ship repairs but these will not regenerate the hitpoints of your turrets so you still have to dodge well, Mines are abundant here, Shields will also be given here but you most likely won't use it.

Boss

 * Final boss - The mission has no intermediate boss, and what this crab looking boss does is it will move around in circles while shooting orange homing bullets at you, this can throw off first timers but what you can do is to circle around the boss or move around in circles in front of the boss, the goal is to attempt and hit the boss with your shots while also making sure that the orange bullets won't hit you, its saws also indicate that you don't want to accidently ram with the boss, its saws can be destroyed to help slightly increase your movement space and also for extra score.

Mission 3: Stone-shower
The first asteroid mission you'll encounter and it is the easiest of the 3, there should be at least 6 types of enemies in here, asteroids do not give score points when destroyed, most of them are small and soft enough to be destroyed but the largest ones will take a few seconds to break with weak firepower, these largest asteroids will also split into smaller ones upon destruction, the largest asteroids only give 1 point but you should still destroy them because if you accidently ram into one of these the damage will be huge, be careful also while maneuvering on tight corners as one single bump on say, an indestructible asteroid could damage you a lot here as well. The mission should be easy, however as mentioned earlier, there are indestructible asteroids in this mission and just like Mission 2, these asteroids will limit your ship movement for a while so you will have to maneuver, these indestructible asteroids are very large, stationary, it could either appear with just 1 on the center, top or bottom part of the screen, or 2 indestructible asteroids will appear on both top and bottom, sometimes on the same row, sometimes the positions of the 2 indestructible asteroids will force you to maneuver in an S pattern, these have cannons in them that can be destroyed with a Super-shot or Laser, stationary asteroid flamethrower turrets are also exclusive to asteroid missions such as this one, what these asteroid turrets do is shoot flames at you when your ship gets into their range, they are durable and bumping into these could also hurt your ship pretty bad too, Advanced Spread-fire will be delayed until the 2:05 mark which shouldn't be too long, Asteroid density will temporarily increase with a text warning immediately after the intermediate boss is destroyed, all the mechanics here (indestructible asteroids, asteroid flamethrowers, asteroid temporary density increase) will be seen in all the 3 asteroid missions (Mission 3, 8, and 13), maximum overall firepower is attained within the 5:00 mark,

Boss

 * Intermediate boss - This boss will fire a bunch of lasers in an unknown pattern, but it will most likely fire 2 lasers first, then alternating, then it will fire 1 laser only on either top or bottom, it will repeat then after firing lasers it will blow flames 3 times, afterwards it will fire lasers again on a different pattern, either one by one or both lasers at once then one laser on either top or bottom, its attacks are fairly simple and it shouldn't be too hard to damage the boss as long as you don't get hit with the lasers.
 * Final boss - The boss that appeared as an intermediate boss earlier will reappear once more as the final boss, same strategy as above will apply, before the boss arrives, several Asteroid flamethrowers will enter the screen, you must destroy them all before the boss arrives so your movement won't be limited, the brown cylindrical spinning ship will occasionally enter the battle to assist the boss.

Mission 4: Through Minefields
This mission will be the first mission with mines and Mine Dispensers that the player will be introduced to, which means there will be a good number of stationary mines around the mission, use the Super-shot to clear them out, this mission will delay the access for Spread-fire for a little so you have to hold on with one turret, you'll get the Spread-fire along with the Advanced upgrade shortly after starting from somewhere around the 1:35 mark, some missions will also do something similar to this as well, it is suggested here that once the Weapon power upgrade will come out of the rocket-like enemy, do not receive it first, wait until you break the power-up ship which should contain both an another Weapon power upgrade and the Rear cannon, get the Rear cannon first then take the 2 Weapon power upgrades after to immediately give your Rear cannon an early good damage boost, this mission has a rare chance of giving you the Support Airstrike power-up which means this is the first mission to allow you to have all extra weapons, but the boss is weak enough that you don't need to use it, if you do get it, keep it for the extra score instead, do the same thing with the Shield as well as you won't need it much for this mission, this mission has at least 5 types of enemies, you will be introduced to the green homing missile ship and fireball shooting enemies, the mission overall isn't hard however you have to be alert as some Mine Dispensers could come out and lay out mines everywhere, only charge your Super-shot when you are going to clear mines, you have to clear out mines whenever you can as trying to evade or maneuver around these mines are dangerous, Turrets have increase value here because the turrets you get can also fire Super-shots and it will increase the range of your Super-shot for mine clearing, this Turret increased value will apply to the rest of the Mine missions, around the 2:43 mark, rocket-like enemies will appear in groups and successfully destroying all of them will give you the Extra life power-up, an another Extra life power-up can be obtained in the 4:24 mark from the green colored bat-like enemy, around the 5:18 mark is where you are expected to have attained maximum overall firepower.

Boss

 * Final boss - The mission doesn't have an intermediate boss, and what this boss will do is similar to the Mission 1 boss, it will fire 8 bullets in 8 directions constantly, it will shoot lasers for 2 seconds then it will blow flames then repeat, it has a tiny hand laying on the bottom that can be destroyed for extra score.

Mission 5: Extreme Heat
This mission will introduce you to the Fireball enemy, an enemy that shoots fireballs in 3 directions which can be very dangerous, the mission has a rare chance of giving you the Support Airstrike weapon but once again the boss in here is weak enough that you don't need to use it, keep it for the extra score, this mission is also very abundant on Guard bots so you will be able to experience having max Guard bots for some time here, this mission has at least 5 types of enemies, this mission will be the debut of the Rammer 2 enemy ship, it looks like a brown mothership of some sort, this enemy ship will not do anything else aside from getting close to you and directly ramming at you, when it does you will take great damage so make sure to shoot them down quick, bat-like green colored enemy ships will constantly come out from the back of your ship but they are easy to destroy, that's all there is to know.

Boss

 * Intermediate boss - The boss that appeared in Mission 4 will reappear here again as an intermediate boss, same description as mentioned above.
 * Final boss - The final boss will have a spinning cannon on its back that will constantly fire 8 bullets in 8 different directions, it has the ability to spawn minions which will try to ram you, it shoots fireballs then afterwards it will fire a laser, if the spinning cannon is destroyed it will reveal an another hole which means the boss will be able to spawn more minions, some normal enemies will enter the boss fight momentarily to assist the boss itself.

Mission 6: Under Heavy Fire
This mission will introduce new enemies for you to fight, with at least up to 7 enemies types to fight against, up to a maximum of approximately 9, the straight 4-shot enemy ship will make its first appearance here and they will appear in groups, they are easy to destroy but their bullets can overwhelm you, bumping into them is not a good idea, this mission will prevent your access to the Advanced Spread-fire until you beat the intermediate boss, but there isn't anything much to worry as the intermediate boss is beatable enough with what the mission provides you, even without using any extra weapons, once more this mission has a fair chance of giving you the Support Airstrike weapon, and while the final boss may seem threatening, it's easy to beat without using anything so keep it for the extra score, Rear cannon will be delayed up until the first minute, this mission is also fairly abundant of the Laser shooting enemy ships and dragon-like enemy ships, these 2 will often appear in groups in this mission, it is expected that you will attain maximum firepower before the intermediate boss, the weak asteroid looking enemy ships will commonly appear in groups on both top and bottom, to counter this formation shoot at the middle on where they are converging into.

Boss

 * Intermediate boss - The boss that appeared in Mission 4 will reappear here again as the intermediate boss but this time there will be two of them, once more the strategy mentioned on how to beat the final boss of Mission 1 is also applicable here due to both bosses having similar attack pattern, this shouldn't give you much trouble even without having the Advanced Spread-fire
 * Final boss - The attack pattern of this boss is quite simple, it will fire a blue powerful laser for at least 3 seconds then it will shoot fireballs for a while, then it will shoot the laser again for a few seconds then shoot fireballs for a while, it will release crates on the bottom hole beside its spinning cannon which shoots fireballs in 3 different directions, this cannon will always be aiming at you and it can be destroyed with either the Rear cannon, accurate Homing missile shooting or with the Shield, the boss will be significantly weaker once the spinning cannon is destroyed, it is also capable of releasing minions that will attempt to ram you as well.

Mission 7: An Overgrown Crab
This mission will be very abundant on Frog enemies (the green colored enemy that moves like a frog), they will come on both sides of your ship so be ready, 2-shot hybrid and Laser enemies are also more common here, the Laser enemy ships will often come in groups, some will also enter the screen fast, the 2-shot hybrid rammer ships will appear either with 2 or 3 of them, immediately select the Mines when you get it and ensure that you can improve your Rear cannon as much as you can, there should be approximately 6 - 7 types of enemies appearing in here, and you'll get plenty of power-ups, the mission isn't too difficult but frog enemies appearing at the back of your ship could be annoying to deal with and this is where your Mines will have better usage but be sure to not lay out too much of them, the safe zone for shooting the frog enemy ships that come out from the back with your front cannons is the top left corner of your screen, do not go into the edge but stay somewhere in the middle in this region, this mission gives you a single Shield but it is suggested to not use it as the boss is easy enough without the Shield, improve your power-up receiving arrangement to improve your Rear cannon as much as possible.

Boss

 * Intermediate boss - The boss that appeared in Mission 2, the one with saws will reappear here as the intermediate boss, same description applies as mentioned above.
 * Final boss - The final boss is some sort of a gigantic robotic crab (as the mission name says) what this boss does is it rapidly shoots fireballs from its 2 cannons on the upper and lower part, the boss will also alternate between shooting flames and lasers within certain intervals, its front claws can be destroyed for extra points, its fireball cannons can also be destroyed which means you can weaken the firepower of the boss significantly, at this point it is recommended to use your Homing Missiles to protect yourself from the fireballs but be careful not to use way too much, the boss will also fire orange homing bullets at you, once the boss HP is completely depleted it will downgrade to the Mission 2 boss that you fought as an intermediate boss earlier, same description applies once more, do not waste your extra weapons here.

Mission 8: Stop the Production
This mission is one of the harder missions of the game, it will basically let you have a taste of the increased difficulty spike the game can offer, this is the second asteroid mission in the game and while this is harder, this isn't the hardest so consider this a warning, the game is harder due to limited supply of power-ups, the enemies that appear in which should be at least 6 - 7 types, and some enemy formations can be quite annoying to deal with, Laser enemy ships will be somewhat common here along with the spinning brown ships that release homing bullets, always aim to destroy these mentioned ships as fast as you can, thankfully the mission is somewhat plentiful with Shields but only use them in dire situations, do not make any reckless moves in this mission, for the first power-up ship it is advised to take the Spread-fire power-up first then Weapon power upgrade next, and if you can, once you destroy the 2nd power-up ship and it drops the Weapon power upgrade, leave it first, wait until you destroy the 3rd power-up ship which should give you the Rear cannon and Advanced Spread-fire, take these 2 first then take the Weapon power upgrade afterwards, it is advised also that you destroy the 5 rocket-like enemy ships that appear in a column right after you see the asteroid flamethrower, destroying all 5 will give you a Shield, once you reach the segment of the mission where a red indestructible asteroid is in the middle, the power-up ship that will appear here contains 2 Turret upgrades, ensure that you break the power-up ship on a safe zone so you can grab the Turret upgrades safely and easily, you should also make sure to do your best in destroying the cannons inside these indestructible asteroids as they will never stop firing at you until you destroy them, the Extra life power-up will be dropped at the 4:20 mark, this mark will vary depending on how fast you've beaten the intermediate boss, somewhere around the 5:25 mark (varies), a group of Laser enemy ships will appear, destroying all of them will give you an Extra life power-up, after this formation, asteroid density will temporarily increase with a warning and some asteroids will appear on top of the screen so be careful.

Boss

 * Intermediate boss - The final boss battle you experienced in Mission 3 will be repeated here as the intermediate boss, Flamethrower asteroids will enter the screen and you must destroy them before the Mission 3 boss will arrive, same description applies to here as mentioned above in Mission 3, this shouldn't be hard as this is already your third battle with this boss.
 * Final boss - The final boss here are 2 asteroid producers, they don't do anything aside from producing as much asteroids as they can, but the problem here is that it means you have more asteroids to deal with and dodge, some of the asteroids that these bosses also make deal some significant damage if you accidently ram into one so you have to be really careful, the Cylindrical spinning ship (brown colored) will also assist the boss here and will serve as its primary firepower, the bosses will limit your movement space a lot while the spinning brown ships will damage you with their homing orange bullets, once one of the asteroid makers are destroyed your situation will be a lot more easier to handle.

Mission 9: Meet Minelayers
This is also one of the harder missions you'll experience in the game, while the mission won't delay your access to some of helpful upgrades, this mission will be more abundant of the Mine Dispensers than Mission 4, enemies that spit out red mines at fast speeds limiting your movement as much as possible, to deal with the Mine Dispensers at the beginning, you have to start the mission taking out the first enemy ship which is the Bat-like enemy with a Super-shot, kill the power-up ship normally then charge a Super-shot, once its ready and the first 2 Mine Dispensers appear, fire your Super-shot on the top Mine Dispenser and destroy the bottom one with your normal shot quickly, charge another Super-shot and fire it on the middle Mine Dispenser, afterwards, charge an another Super-shot and release it on the top Mine Dispenser, then destroy the next 2 Mine Dispensers normally, this will make your beginning very smooth, there is also somewhat limited extra weapon supplies, you have to rely on your Super-shots mostly to clear out mines as much as you can while also destroying enemies, some power-ups interestingly are covered with mines and to safely get them you must use what you can use to destroy the mines surrounding these power-ups so you can get them, there are at least 6 enemy types that appear here, be wary of Mine Dispensers always, don't let them lay out many mines in your screen, this mission will also train you to be better when it comes to clearing out mines, there will be a lot of stationary mines in here so you have to be really careful while moving around, rocket-like enemy ships and bat-like enemy ships will be common here, the 2nd group of rocket-like enemy ships that will appear after the first one will give you a Shield when all of them are destroyed at the beginning of the mission, within the 2:10 mark you should have already obtained your Rocket turrets, anywhere starting from 30 seconds before this mark, and after this mark, you should simply keep firing at the right side of the screen where your ship is facing while moving up and down to prevent Mine Dispensers from having a chance to lay out mines, only charge your Super-shot if you are going to clear a lot of stationary mines, an another group of rocket-like enemy ships will drop a Shield when all ships are destroyed too in 2:42, if you are having difficulties with clearing out Mines, don't be afraid to assist yourself with extra weapons to help ease up the situation.

Boss

 * Final boss - The final boss in this mission is that it has 2 cannons on its top and bottom part, it is capable of shooting 3 fireballs in a spread out manner with moderate firing speed, these can be destroyed to help reduce the firepower of the boss, the boss also shoots a blue laser which is dangerous, as one blast from this laser will immediately kill you, after firing its laser for a few seconds, it will blow flames for at least 2 - 4 times, then it will shoot fireballs for a while, then it will shoot its laser again, the process will repeat, the boss is also capable of releasing minions which will do nothing else aside from trying to ram you, this is arguably the strongest frog boss yet out of the other ones you've faced.

Mission 10: Dragon's Lair
An easy mission, this shouldn't cause too much difficulty for you however the mission will delay your access to the Rear cannon for a minute, this mission will also be very abundant of Dragon-like enemies (all 3 of them), the Laser enemy ships, and the straight 4-shot enemy ship, the 2 variants of dragon-like enemy ships will appear both at the front and back of your ship, they appear in numbers and the blue-colored dragon-like enemy ships can enter the screen at fast speeds although they should be easy to deal with, Mines can be useful for the red-colored variants that appear on the back but they should be easy to destroy with just your Rear cannon alone, just avoid their shots, the mission contains at least 7 enemy types, it is somewhat advised here that you take the Spread-shot power-up first before taking the Weapon power upgrade, the mission doesn't offer much extra weapons but the bosses can be destroyed without even using them, the mission will also delay your access to the second normal turret for almost 2 minutes so you will have to stay with 1 until then, the mission has a certain segment near the final boss battle where the 4 shot straight enemy (please refer to the Enemies section) will appear in a vertical group covering an entire column and when they fire, their shots will cover the entire screen, to counter this you must make the preemptive move or anticipate their arrival, once you've noticed that 5 of these enemies will appear in a group then the next group that will appear is the one mentioned above, if you fail to destroy one of the ships on the last group and it manages to fire, use your Homing Missiles to protect yourself from the barrage of shots immediately, it is also advised that you avoid staying at the top and bottom part of the screen after defeating the intermediate boss as your Turrets may accidently ram into an incoming straight 4-shot enemy ship that could come out from these parts of the screen, a single bump from this enemy ship will immediately downgrade your Turret.

Boss

 * Intermediate boss - The final boss of Mission 5 will return here as the intermediate boss, same description applies as mentioned above, some enemies will come in to assist the boss for extra firepower, this boss shouldn't make you use a power-up.
 * Final boss - The final boss here is difficult but dealing with it can be easy once you learn the safe spot when fighting it, the look of the boss and the way it fires its lasers (2 shots, with a good distance gap between them) may give you an idea that its best to stay in the center to deal as much damage to the boss as possible, however this isn't a good idea especially if you are terrible at dodging, so instead you have to stay on the top part of the screen, above the top laser it fires, the boss fires 4 bullets from spinning cannon, orange bullets with its lower cannon, all at low - moderate firing speed, it also has a top cannon that fires green homing bullets at you with above moderate firing speed, not fast because it has a delay after firing a number of these bullets, staying at the top segment should allow you to avoid these homing bullets a lot easier, when the boss arrives make sure you stay on the very top or bottom because it will immediately fire its laser, and its laser is deadly, enemies will also appear here to assist the boss.

Mission 11: Flying Frogs
This mission will be very abundant with the Frog enemies once more just like in Mission 7, the mentioned safe zone on Mission 7 for the frog-like enemies that will appear at the back of your ship also applies to this mission, it is also fairly abundant with the crab-like enemies (white-colored), it is advised here that at the start of the mission, take both the Spread-fire and the Rear cannon first before taking the Weapon power upgrade, the mission has at least 6 types of enemies, and once again this is an easy mission, except for the final boss, the mission doesn't give much extra weapons and there is a warning that you have to take note: Do not use the Shield until you reach the final boss as you will need it to counter them, Laser supplies will be almost rare that sometimes you may not even get anything at all, it is expected that you will attain maximum firepower somewhere around after the intermediate boss, somewhere around 6:05 - 6:15 mark depending on how fast you took down the intermediate boss, the bat-like green colored enemy ships will appear in groups at the back of your ship that may overwhelm you and destroy your turrets, to prevent this one can anticipate its arrival, the 8 bat-like enemies split into 2 groups will first appear on both the top and bottom part of the screen, after this the overwhelming group of bat-like enemies will come out next, all you have to do is aim your Rear cannon at them properly slowly keeping your distance while releasing out as many Mines as possible, when done correctly they shouldn't be able to damage you a lot and you get to keep your turrets.

Boss

 * Intermediate boss - The final boss of Mission 5 will return here as the intermediate boss, same description applies as mentioned above, however this time 2 will appear and this may make the fight a little more troublesome, you have to stay in the middle and ensure you won't get hit, you will have to deal with a swarm of minions but these shouldn't cause too much problems, if you want to destroy the spinning cannons you can do so by aiming for its slightly exposed part at the top part of the boss, it will be destroyed easily without you having to use a extra weapon, destroying the spinning cannons will increase the amount of minions they can spawn but that isn't an issue anyway.
 * Final boss - The final boss in Mission 6 will appear here as the final boss so the same description applies as mentioned above, however this time 2 will appear and this is probably one of the most difficult boss fights yet, however this will be much easier to handle if you kept the Shield all the way until here, the reason why you must use your Shield here is because the spinning cannons that the bosses possess can be destroyed, and yes you cannot risk yourself to destroy them with your rear cannons but that's why you have the Shield, so use it, then go directly into the fireball spinning cannon the 2 bosses have and destroy them immediately before your shield is over, the boss fight should be easier to manage from this point onward, all you have to do is stay on the top segment of your screen, hit them with your shots, don't get hit by their laser, and take care of the minions, some enemies will also arrive to assist the boss.

Mission 12: Don't Get Stabbed
This mission so far is fairly easy, the mission itself contains at least 5 - 6 enemy types, with the most notable ones being the Rammer 2 enemy ship and the dragon-like enemy ships having common appearance in here, Laser enemy ships and Rocket enemy turrets are also fairly common, somewhere around the 5:00 - 5:05 mark you will get an Extra life power-up, extra weapons here are back to their usual abundance, you could even get a Support Airstrike here but it is recommend that you shouldn't use it, as even the final boss is easy to take care without using any extra weapons, the mission will delay your access to the Advanced Spread-fire and you will get it after you beat the intermediate boss, the mission will spam the red-colored dragon-like enemies first somewhere around near the final boss, this can be easily dealt with by aiming your Rear cannon properly while also throwing around mines, the mission will then spam the Fireball shooting enemy ships after in numbers of groups, you just have to keep shooting at them and destroy them before they get the chance to shoot, if they do, use your Homing Missiles to protect yourself, afterwards the final boss for this mission will enter.

Boss

 * Intermediate boss - The final boss from Mission 7 will return here as an intermediate boss but there are significant nerfs, first of all the fireball cannons that this boss has will have an even slower fire rate so you shouldn't worry as much, the fireball cannons itself can also be destroyed so it won't shoot fireballs anymore, it will still fire orange homing bullets fast enough but they should be easier to avoid this time, the boss will also not release any sort of downgrade or smaller boss, once its destroyed, that's it.
 * Final boss - The final boss here has a front facing spike, it has a lower spike swinging slighty on the bottom that can be destroyed for extra score, the attacks of this boss are fairly simple to recognize, it fires 3 straight rockets, it fires single orang bullets with moderate firing speed, the boss will also rapid fire 3 fireball shots in 3 directions but it should be easy to avoid, the boss also fires green homing missiles but it will take somewhat long enough before it can fire the homing missiles again, if you notice how the boss moves it has some sort of a predictable loop, once it gets to a certain segment somewhere around the upper section of the screen, it will dash forward and stab its spike, this attack will one-shot you if you ever get hit, but this attack shouldn't kill you as long as you aren't shooting the boss directly on front of it, once the boss HP is depleted it will downgrade to the boss you've fought on Mission 1, same description applies as mentioned on its section, the boss should be easy, no need to waste your Support Airstrikes, keep them for a lot of extra score.

Mission 13: The Last Avalanche
This is by far the most difficult mission in the game due to its variety of enemies (there are 7 in total, some of them are quite threatening such as the Rammer variant 2 and the Cylindrical spinning brown ship) as well as somewhat dense amount of large asteroids, your extra weapon supply on this mission will be low, Repair life is also very few here so you have to avoid as much damage as possible, the mission will give you with up to at least 3 shields and you definitely want to use this if you want to protect yourself and your turrets, the mission will immediately grant you access to Advanced Spread-fire so you must obtain it as soon as possible to help fend off Rammer 2 enemy ships, once again it is recommended here to destroy the cannons residing within the indestructible asteroids whenever you can with Super-shots, as their bullets hurt and they fire fast, one good segment to immediately use your shield is somewhere around the 1:30 minute mark where Laser variant 2 enemies appear and you will see a huge red rock with the asteroid cannon in it, it will be extremely hard to come out of here unscathed because the Asteroids warning will appear immediately and Rammer 2 enemies will come in twos, if you want to ensure that your turrets and your ship will not break, use your Super-shot to destroy the cannon inside the red rock, get the turret power-ups then activate your Shield and move away from the red rock blasting into the asteroids and rammer enemies without going directly into rock as even with the Shield, you may lose your turrets if you go into the huge rock, you can use a little bit of Homing Missiles to help clear out the way, what you also have to watch out the most is the fair abundance of Laser and homing bullet enemies as they will make you move a lot on this limited movement mission, within the first few tries you may die for at least 1 time, but its definitely possible to come out of here without dying, all it takes is just the correct Shield activation and some practice, the spinning brown ships will constantly appear both at the front and at the back and you can use your Mines to quickly dispose them, if there are too much on the screen you can use your Shield to protect yourself if needed, but make sure that your Mines will actually hit since as mentioned above, extra weapon supply is low here,

Boss

 * Intermediate boss - The final boss you've battled in Mission 8 will reappear here as the intermediate boss, but instead of just 2 there will be 3 of them so the battle will be even more difficult, if you have some Shields at this point don't be shy to at least use 1 if your ship is in danger, as while the description mentioned above applies here, the difficulty will be significantly amplified due to 1 more extra boss, once you're able to destroy at least one, the boss battle should be easier to manage, I recommend destroying the very top boss first before shooting the middle one, and save your extra weapons as much as you can too, spinning brown ships will constantly pay a visit to make the battle harder so make sure to take them down quick and evade their bullets.
 * Final boss - The final boss in this mission is actually somewhat easier compared to the intermediate boss, the boss fires single green homing missiles with moderate delay in between, it shoots a green, high damage laser for at least 3 seconds, it fires 8 bullets through its spinning cannon at the back on 8 different directions, the boss also fires 3 fireballs rapidly in 3 directions with moderate delay per rapid burst, the boss is capable of producing minions that will ram at you, the boss is also capable of deploying asteroids with high durability that will revolve around the boss itself to act as guard bots, it will launch at least 2 - 3 of these, the boss has a lot of attacks to use but it should be easy enough to handle all of them, just don't get too close to the boss for the revolving asteroids to hit you.

Mission 14: Need to Break Off
After the immense struggle you went through with Mission 13, this mission should be able to give you a breath of fresh air as it is once again fairly easy, with slight caveats such as Mine Dispensers returning and having a common appearance as well as fair abundance of the spinning brown ship but these shouldn't give you much problems as the mission itself has plentiful of extra weapons and it doesn't delay your access to most upgrades, it is once again advised that you take the Rear cannon first before taking the Weapon power upgrade, use your Mines wisely to dispose the spinning brown ships early in the mission, the 3 Laser enemy ships that appear early in the mission can be difficult to deal with but you must destroy them for some valuable drops, you can ram into them once they have taken enough damage from your shots, you will get your Spread-fire and Turret upgrade once approximately a minute has past, this mission also has a chance of giving you the Support Airstrike weapon but once again it is would recommended that you to simply keep it, there are at least 7 types of enemies here that will be encountered, there is a certain segment somewhere around 6:49 mark where tons of cylindrical spinning brown ships will appear in great numbers from behind which will happen at least a minute after the intermediate boss, the mission will give you 2 Shields and you will use one here but you have to wait first until many more brown ships will appear before you activate it, once there are at least 2 groups of brown ships in the screen, activate your Shield and release a lot of Mines around and directly into the brown ships to help clear out the horde, there are also stationary mines in here just like what Mission 9 has and it should be easy to clear them out with Super-shot, you'll attain maximum firepower in as early as 3:20, and at 3:40 if you are able to kill the 3 spinning brown ships that appear at your back you will get an Extra life, Mine Dispensers here as mentioned above will appear a number of times and just like in Mission 9, to deal with them easily you just have to keep firing at the side where your ship is facing while hovering up and down to immediately kill these enemy ships when they appear, the last segment of the mission has stationary mines that can be difficult to eliminate so you may use your Lasers here for some assistance, after this segment the final boss for the mission should now appear.

Boss

 * Intermediate boss - The final boss you fought in Mission 12 will return here as the intermediate boss so the same description as mentioned above should apply here except with a twist, once the boss HP has been depleted and it will downgrade to the Mission 1 boss, the boss will approach really close to the left edge of the screen, forcing you to destroy the boss using your Rear cannon, it isn't much of an issue as for one that means only its green bullets can hit you, and it won't take too long as well, using Mines can be a good idea but it won't help much unless you are good at making Mine clusters.
 * Final boss - The final boss here is the boss you've fought in Mission 9, so the same description as mentioned above will apply here however this time, there will be 2 of them and this fight can be significantly difficult if not handled well, but as always there is a counter for that, once the 2 bosses arrive you must use your Shield (you should have at least 1 more remaining) once you have activated it immediately destroy the top and bottom fireball cannons of the upper frog boss, then only the top fireball cannon for the bottom frog boss, use your Homing Missiles and Lasers to accelerate the process, once the fireball cannons are destroyed you can sit back and relax a little, you don't have to use the Support Airstrike here unless you failed to destroy the mentioned fireball cannons, the bosses should be easy to deal with afterwards, you can destroy the bottom frog first as it is more accessible then take down the upper frog boss next.

Mission 15: Coup De Grace
The final mission in the game, and so far it is also fairly easy, the bat-like enemy you've once fought in Mission 1 for example will return here with a significant buff to their firing speed so you have to take these down as soon as you see them, the green colored bat-like enemy ships, and ships that fire green homing missiles are commonly seen here, it is extremely advised here that you take the Rear cannon power-up first before taking the 2 Weapon power upgrades at the early segment of the mission, there should be at least 6 - 7 enemy types here, and this mission will be plentiful of power-ups, the mission will also give you a Support Airstrike and Extra life somewhere around the 4:53 - 5:00 mark from groups of bat-like enemy ships that appear at the back and this is pretty much the only applicable use of the power-up in the game because the final boss here is extremely difficult to take down without using it, there is a slight warning here that after you have beaten the intermediate boss, beware of the front, upper, and bottom parts of your screen as you may accidently ram into a straight 4-shot enemy, ramming into one of these will kill you pretty easily so don't move very recklessly, that's about it, beat the mission and you beat the game.

Boss

 * Intermediate boss - The boss you've fought in Mission 10 will return here as the intermediate boss, there are no changes as to how it attacks so the same description as mentioned above will apply here as well, do not use any power-ups here as it is not needed, just dodge well and you'll defeat this boss without breaking a sweat.
 * Final boss - The final boss here has only 2 ways of attacking you but it is extremely deadly, it has 2 back spinning cannons firing 8 orange bullets in 8 different directions with fast firing speed, and finally the front cannon fires 5 homing bullets at you with fast firing speed, it doesn't fire any lasers but the homing bullets here will kill you pretty fast because you don't have much space to avoid them thanks to the back spinning cannons, use your Support Airstrike to deal some significant damage and fire 1 Homing Missile per second to avoid using too much and so that your Homing Missiles could still contribute to your score, the boss is quite durable but the battle shouldn't take way too long, that's it, congratulations you have beaten the game!
