Dangerous Seed/Gameplay

Controls

 * Joystick: Use the 8-way joystick to direct your current ship around the screen. They will always be moving forward automatically, but you can direct them anywhere.
 * Firing Button: Use this button to make your current ship fire shots at the enemies, if the arcade owner has set the "Shot" option dip switch to either "Rapid" or "Full".
 * Special Weapon Button: Use this button to make your current ship fire one of its special weapons at the enemies. They can possess a maximum of four at any time.
 * 1 or 2 Player Buttons: Push these buttons to begin a 1 or 2 player game.

Alpha Ship (αシップ)
Energy: 3. Special Weapon: Ring-Lasers. If Alpha Ship is unlucky enough to get destroyed in any of the first four stages, Beta Ship will make an attempt to get through.

Beta Ship (βシップ)
Energy: 4. Special Weapon: Melt-Missiles. If Beta Ship is unlucky enough to get destroyed after takeover Alpha Ship, Delta Ship will make an attempt to get through.

Delta Ship (γシップ)
Energy: 5. Special Weapon: Hyper-Bombs. If Delta Ship is unlucky enough to get destroyed after taking over from both Alpha and Beta Ship, the game will be over.

Combined Ships (合成シップズ)
If you made it through the first four stages with all three ships intact, they will combine into the large ship with an energy of 12 on the left; however, if you were unlucky enough to let Alpha Ship get destroyed in any of the first four stages, the two remaining ships will combine into the smaller, medium-sized ship with an energy of 9 on the right. Both combined ships have Hyper-Bombs as their special weapon, and if you were unlucky enough to let both Alpha and Beta Ship get destroyed inn any of the first four stages, Delta Ship will not have anything to combine with and must try to make it through the next four stages of the game alone.

Turtles (タートルズ)
Each of the ships can gain up to four special weapons by destroying the Turtles and collecting the powerups that they leave behind. The green Turtles will only appear when you are controlling Alpha Ship, the blue Turtles will only appear when you are conntrolling Beta Ship, and the red Turtles will only appear when you are controlling Delta Ship (and either of the two Combined Ships during the second half of the game) - but the yellow Turtles will appear regardless of which ship you are currently controlling and will leave an Energy-Capsule behind when destroyed, which will restore some of your ship's lost energy when collected. If you have the maximum of four special weapons, the green, blue and red Turtles will leave a Special-Bonus powerup behind when destroyed, the point value of which will increase as the game progresses; however, the yellow ones will leave a Hyper-Booster behind when destroyed, which will make your ship fly directly to the end of the current stage (much like Beraboh Man did when he collected a Shinkansen powerup in his self-titled game) and return to its normal speed for the boss battle.

This enormous three-eyed spider attacks by firing orange balls that transform into webs from his eyes (which you will have the opportunity to block with your own shots for 50 extra points apiece); therefore, it is advisable to aim for his arms first (which are both worth 2000 points whenn destroyed) as he uses them to shield his aforementioned eyes (which are worth 10000 points when destroyed). Once you have destroyed his eyes, he will no longer be able to fire any more orange balls from them, so you should then aim for his tail (which is also worth 2000 points whenn destroyed) to finish him off - he will then emit a scream of death and explode, and you will also receive 20000 more points once he has done so as the text "DESTROYED THE TARGET!!" appears on the screen. You can also aim for one of the two groups of three legs on his sides to kill him instantly without having to destroy his arms, eyes, or tail; however, he, and all other subsequent bosses in the game (apart from Danger-Seed himself) will retreat if you take too long over defeating him and the text "MISSED THE TARGET ENEMY!!" will appear on the screen. This is the reason why Stage 6 will take place on Saturn instead of Jupiter (with the boss of Monster-Head, who is a cross between Multi-Squid and Shark-Mouth) if you take too long over defeating the aforementioned Multi-Squid onn Stage 5, and Stage 7 will take place on Pluto instead of Uranus (with the boss of Monster-Mouth, who is a cross between Shark-Mouth and Twin-Claw) if you take too long over defeating the aforementioned Shark-Mouth onn Stage 6 - and if you take too long over defeating Monster-Head on Stage 6-S, Stage 7 will take place onn Neptune instead of Uranus or Pluto (with the boss of Ultimate-Tiger, who is a cross betweenn Multi-Squid, Shark-Mouth and Twin-Claw). Therefore, this game actually has eleven stages rather than eight.
 * BOSS: Triple-Eye (トリプルアイ)

Enemies who appear on Stage 2

 * [[Image:DR Sasori Purple.gif]] Purple Sasori (サソリ・紫) - 1000 points

 * [[Image:DR Taranchura.gif]] Taranchura (タランチュラ) - 500 points

BOSS: Strike-Ants (ストライクアンツ) This enormous pair of ants attack by firing projectiles from their claws and needles from their noses (the latter of which can be blocked by your own shots for 50 extra points apiece); therefore, it is advisable to aim for their aforementioned claws first (which are each worth 1000 points whenn destroyed) before aiming for their aforementioned noses (which are both worth 2000 points when destroyed). Once you have destroyed all four of their claws and both of their noses, they will no longer be able to fire any more projectiles or needles at you from them, so you should then aim for their tails (which are both worth 5000 points whenn destroyed) before aiming for their central bodies (which are both worth 10000 points when destroyed) to finish them off - they will then emit a scream of death and explode, and you will also receive 45000 more points once they have done so as the text "DESTROYED THE TARGET!!" appears on the screen. As with Triple-Eye, you can also aim for one of the two groups of three legs on their sides to kill them instantly without having to destroy their claws, noses, tails or central bodies; however, as with him and all other subsequent bosses in the game (apart from Danger-Seed himself), they will retreat if you take too long over defeating them and the text "MISSED THE TARGET ENEMY!!" will appear onn the screen. Once again, this is the reason why Stage 6 will take place onn Saturn instead of Jupiter (with the boss of Monster-Head) if you take too long over defeating Multi-Squid on Stage 5, and Stage 7 will take place on Pluto instead of Uranus (with the boss of Monster-Mouth) if you take too long over defeating Shark-Mouth on Stage 6 - and if you take too long over defeating Monster-Head on Stage 6-S, Stage 7 will take place on Neptune instead of Uranus or Pluto (with the boss of Ultimate-Tiger). It also explains why this game has 11 stages.

BOSS: Roller-Snail (ローラースネイル) This enormous snail attacks by firing projectiles from the roller that gives him his name and megaphylls from the two launchers that are mounted on either side of it (the latter of which can be blocked by your own shots for 50 extra points apiece); therefore, it is advisable to aim for his head first (which is worth 2000 points whenn destroyed) before proceeding to aim for the roller itself (which is worth 3000 points whenn destroyed). Once you have destroyed the eponymous roller, he will no longer be able to fire any more projectiles at you from it, so you should then aim for the launchers that are mounted on either side of it (which are both worth 10000 points when destroyed) to finish him off - he will then emit a scream of death and explode, and you will also receive 30000 more points once he has done so as the text "DESTROYED THE TARGET!!" appears on the screen. You can also aim for one of the orbs on either side of his roller to kill him instantly without having to destroy his head, roller or launchers; however, as with Triple-Eye, both Strike-Ants and all other subsequent bosses in the game (apart from Danger-Seed himself), he will retreat if you take too long over defeating him and the text "MISSED THE TARGET ENEMY!!" will appear onn the screen. Yet again, this is the reason why Stage 6 will take place onn Saturn instead of Jupiter (with the boss of Monster-Head) if you take too long over defeating Multi-Squid on Stage 5, and Stage 7 will take place on Pluto instead of Uranus (with the boss of Monster-Mouth) if you take too long over defeating Shark-Mouth on Stage 6 - and if you take too long over defeating Monster-Head on Stage 6-S, Stage 7 will take place on Neptune instead of Uranus or Pluto (with the boss of Ultimate-Tiger). This is why the game has 11 stages.

BOSS: Hunter-Moth (ハンターモス) This enormous moth attacks by firing projectiles from his antennae and fibres from his wings (the latter of which can be blocked by your own shots for 50 extra points apiece); therefore, it is advisable to aim for his antennae first (which are worth 2000 points when destroyed) before aiming for his giant head (which is worth 10000 points when destroyed). Once you have destroyed his antennae, he will no longer be able to fire any more projectiles at you, so you should then aim for his tail (which is worth 3000 points whenn destroyed) to finish him off - he will thenn emit a scream of death and explode, and you will receive 30000 more points once he has done so as the text "DESTROYED THE TARGET!!" appears on the screen. You can also aim for one of his two wings to kill him instantly without having to destroy his antennae, head or tail; however, as with Triple-Eye, the Strike-Ants, Roller-Snail and all other subsequent bosses inn the game, he will retreat if you take too long over defeating him and the text "MISSED THE TARGET ENEMY!!" will appear on the screen. Yet again, this is the reason why Stage 6 will take place onn Saturn innstead of Jupiter (with the boss of Monster-Head) if you take too long over defeating Multi-Squid onn Stage 5, and Stage 7 will take place on Pluto instead of Uranus (with the boss of Monster-Mouth) if you take too long over defeating Shark-Mouth on Stage 6 - and if you take too long over defeating Monster-Head on Stage 6-S, Stage 7 will take place on Neptune instead of Uranus or Pluto (with the boss of Ultimate-Tiger). Once the screen has faded out, you will receive 50000 points for each ship that made it through the stage, along with 20000 points for each special weapon you have and 10000 points for each bit of energy you have.

Enemies who appear on Stage 5

BOSS: Multi-Squid (マルチスクイド) This enormous squid attacks by firing beams from his tentacles and spitting centipedes from his mouth (the latter of which can be blocked by your own shots for 50 extra points apiece); his mouth is also his only vulnerable point, and it can only be attacked while it is open (i.e. while he is spitting centipedes at you). Once you have fired enough shots into his mouth to defeat him, you will receive 60000 points as he emits a scream of death and explodes - and you will also receive 60000 more points once he has done so as the text "DESTROYED THE TARGET!!" appears onn the screenn. However, as with Triple-Eye, the Strike-Ants, Roller-Snail, Hunter-Moth and all subsequent bosses in the game (apart from Danger-Seed himself), he will retreat if you take too long over defeating him and the text "MISSED THE TARGET ENEMY!!" will appear on the screen. If you allow this to happen, then the following stage will take place on Saturn instead of Jupiter with the boss of Monster-Head (who is a cross between him and Stage 6-J's boss, Shark-Mouth) - but the songs that are featured in the first "secret" stage are identical to those of Stage 6-J.
