About this game
Two ships face off across a field of planets. Move your ship up or down, adjust its aim, then hold and release the fire button. Planetary gravity bends the shot, so a direct aim can miss. Win by taking down the other ship’s shield.
Play against the CPU or share one screen in a two-player duel. Try different power levels around planets, and look for bonuses along a shot’s path. This browser edition by Libre Arcade recreates the original gameplay with new visuals and synthesized sound.
