''Dogyuun'' is an [[ArcadeGame arcade]] ShootEmUp made by {{Toaplan}} in 1992.

The plot is somewhat vague, except that it involves two pilots destroying aliens after an alien mecha kills the reconnaissance ship leading them.

One interesting feature of the game is the ability in CoOpMultiplayer for player 1 to [[CombiningMecha combine]] with player 2, producing a larger ship with better firepower. The game also features loads of homing lasers and large bosses. It was also the first game to feature the astounding graphical designs of Creator/JunyaInoue.

'''This game displays the following tropes:'''

* AIBreaker: The easiest way to beat the scorpion boss is to have the red weapon, destroy one of its claws, that stay in the top corner on the same side as the destroyed claw. None of his attacks will be able to get you, and your red homing laser should be able to damage him.
* AttackItsWeakPoint: The second boss can only be damaged when it opens its chest to charge and fire out a WaveMotionGun.
* BatOutOfHell: You face several bat mechas in stage 6.
* BeamOWar: If you have the [[WaveMotionGun blue weapon]], you can try to counter the second boss' WaveMotionGun with yours. You'll probably lose, though, as he fires ''two'' while you only fire one.
* ChainReactionDestruction: Bosses die in this manner.
* CombiningMecha: Player 1 can combine with player 2, forming a larger plane with stronger firepower.
* CoolBike: One of the enemies in stage 7 is a mech on a motorbike.
* CorridorCubbyholeRun: Stage 5's boss. He sends these [[http://www.shmups.com/reviews/dogyuun/images/dogy0128.png shield things]] that block your shots- do NOT destroy these quickly, as he'll send down a [[http://www.shmups.com/reviews/dogyuun/images/dogy0135.png massive wave of energy that will be blocked by them]].
* DirectContinuousLevels: Present for each level. One neat feature of the game is that you actually fight some of the previous stage's enemies at the start of the next stage.
* DiscOneFinalBoss: Subverted with the golden robot which kills your friend in the intro, and [[VillainExitStageLeft escapes]] in stage 1. Although it ''does'' look like a BigBad or TheDragon, is [[LawOfChromaticSuperiority golden]] in colour, and is the prime reason why you're fighting, it's only the second boss out of 10 stages.
* EndlessGame
* FakeUltimateMook: The first MiniBoss. You fight this huge thing right after the first wave of Mooks, but it goes down very quickly.
* FeatheredFiend: The MiniBoss of stage 4 is a giant robot eagle that can extend its talons to crush you.
* FlashOfPain
* GiantSpider: A GiantMook faced in stage 8.
* HighSpeedBattle: The start of Stage 3 is like this.
* HomingLaser: The purple and the red weapon do this.
* HoverBoard: The first MiniBoss of stage 7 rides a large one.
* HumongousMecha: Many of your foes are these. You get to pilot an invincible one at the start of the final stage. And it is awesome.
* MacrossMissileMassacre: One of the {{miniboss}}es does this to you.
* MiniBoss: At least one per level.
* NintendoHard
* NinjaPirateZombieRobot: The boss of stage 8 is a zombie robot thing.
* NitroBoost[=/=]{{Overdrive}}: The blue attachment allows the player to move quickly by holding down the second button. There is no drawback to this other than making you more prone to colliding with enemy fire.
* NoPlotNoProblem
* NumericalHard: Enemies get more health every time you complete a loop. They do give out more points, however.
* OneHitPointWonder
* OneManArmy
* PowerAtAPrice: Combining player 1 and 2 is cool and increases your firepower, but if you are hit, ''both'' players lose a life!
* PrecisionGuidedBoomerang: Third boss throws these at you.
* RoaringRampageOfRevenge: Your characters presumably do this after the gold mecha kills their friend.
* RocketPunch: The minibosses of stage 5 attempt this on you.
* SegmentedSerpent: You fight one in Stage 8.
* ShowsDamage: Electrical currents starts appearing on bosses as their health gets low.
* SmartBomb: The pink attachment allows the player to use one.
* SpreadShot: The green lightning gun. Many of your foes will use this too.
* ScaryScorpions: The fourth level features many scorpion mechs, the boss is a gigantic one.
* TankGoodness: The first boss. You also fight several tank-based enemies in the game.
* TechnoWreckage: Stage 8.
* UnexpectedGameplayChange: At the start of stage 10, you get to pilot a HumongousMecha via powerup. More lenient tham most examples, though, as the mecha is invulnerable and cannot be destroyed.
* WaveMotionGun: The Blue weapon. You start out with this. Stage 2's boss and stage 3's boss also use this on you. Stage 5's boss uses one so massive, you have to hide behind one of his shielder drones to avoid it!
