🎮 Play Gingateikoku No Gyakushu Online (Arcade)

Gingateikoku No Gyakushu (also widely known as UniWar S) is a vertical-scrolling space shoot-’em-up released for arcades by Irem in 1980. Running on hardware similar to Galaxian, it features a four-stage loop where players pilot an arrowhead-shaped vessel against waves of aggressive alien invaders, including the game’s recognizable “super mosquito” enemies.

How to Play

The objective is to clear each of the four distinct stages by destroying all enemies before they overwhelm you. A unique threat comes from enemies that drop “space soldiers”—these soldiers can land at the bottom of the screen and attempt to attack your ship from behind. For arcade games in the browser, use the Arrow keys to move, Z or X to fire, Shift to insert a coin, and Enter to start.

Tips

• Watch out for the “Killer King” enemy that appears randomly; destroying it clears away any enemy soldiers that have successfully landed.
• Prioritize destroying the enemies that drop space soldiers to prevent them from building up behind your line of defense.
