Here are some techniques the player can learn while playing the game, these techniques are not needed for casual gameplay, these can however help improve the experience and skill the player has for the game, as well as making missions where these techniques are applicable to be more manageable.
Guard bot smash[edit]
This technique involves smashing your Guard bot to an enemy to inflict some significant melee damage, Guard bots are not just good for defense but they are also good for some free damage if you think you can survive without the Guard bots, to do this technique simply approach an enemy ship and smash the Guard bot into them to deal some good damage, a single Guard bot can destroy most enemies, and heavily damage durable enemies like the asteroid flamethrower turret and Fireball shooting enemy, this technique is also applicable for clearing out Mines, a single Guard bot should be able to take out at least 3 - 5 enemy mines before exploding.
Close range shooting[edit]
This technique involves getting really close to an enemy ship and making sure that your Spread shots will hit the enemy ship as well, this technique is really good against durable enemy ships or turrets as sometimes, trying to destroy them with just your main cannon alone isn't quick enough, this is one of the easiest techniques to do and you may have been doing this already.
Super shot special usage (Asteroid and Mine levels)[edit]
The super shot in Astrobatics can be performed by not firing for a while and letting the blue bar on the top part of the screen charge as mentioned by Basic mechanics, aside from being good to use on weak enemy hordes, the super shot is good to use against cannons inside an indestructible asteroid found in Missions 3, 8, and 13, you just have to aim at the center where the cannons reside, the super shot is also good in destroying mines, which is found mainly in missions 9 and 14 (there are probably more, but mines debut on as early as Mission 4), this will help save your Laser in clearing the mines, but take note that you will be vulnerable for a little while when you try to charge your shot.
Power-up special usage and receiving efficiency[edit]
This is a combination of several minor techniques all at once, for one, if the level gives you a choice to pick either a Weapon Power Upgrade or Rear-shot/Spread Fire/Turret, ALWAYS take the latter first before you take the Weapon Power Upgrade, this will allow you to increase the firepower of both your Rear-shot/Spread Fire/Turret with your main cannon more efficiently as this means you need less Weapon Power Upgrade power-ups to get before you reach maximum firepower, second, the Homing Missile and Laser have other uses aside from just destroying enemies, Homing Missile can be used to protect yourself from enemy fire as the missiles have a hitbox too just like the green homing missiles you take down that come from enemies, this also means Homing Missiles can destroy Mines, Lasers can also be "panned", basically move your ship upward or downward then fire your Laser, but this is only effective in destroying weak enemy hordes and clearing out mines, Laser can also be used to shoot the cannons inside the big indestructible asteroid in Asteroid levels, but requires accuracy in doing so.
Weapon Combinations[edit]
Certain weapons can be combined to have a more desired effect (Support Airstrike + Homing Missile, Super shot + Laser), for example Support Airstrike can be combined with Homing Missile, once you activate Support Airstrike and the ships come in, you can fire Homing Missiles along with them to have better damage output, Laser can be combined with Super shot to further augment the damage of your Laser, and finally Mines work better in taking down rear enemies when combined with your rear cannon.
