🎮 Play Gingateikoku No Gyakushu Bootleg Set 2 Bootleg Online (Arcade)

Gingateikoku No Gyakushu (internationally known as UniWar S) is a classic 1980 vertical space shooter originally developed by Irem. This specific version is an arcade bootleg playable directly in your browser. The game distinguishes itself from other early shooters by cycling through four distinct stages: while the first stage plays similarly to Galaxian with diving alien formations, subsequent stages introduce a unique mechanic where enemies drop “Stick Aliens” that attempt to land behind your defensive line and attack from underneath.

How to Play

As an arcade emulation, the controls map standard arcade inputs to your keyboard. Use the Arrow Keys to maneuver your ship left and right across the bottom of the screen. Press Z or X to fire at the alien formations. To begin playing, you will need to insert virtual coins by pressing Shift, followed by Enter to start.

Tips

• Watch your rear: In stages 2 through 4, prioritize the aliens attempting to drop behind the dotted blue line. If they land successfully, they will patrol beneath you and try to shoot your ship from behind.
• Target the Killer King: When a “Killer King” alien appears randomly on screen, shooting it is the key to eliminating the persistent enemies that have successfully landed behind your line.
