Clone of the Atari 2600 game Yars' Revenge. The player must dispense of their enemy's shields (located at the right side of the screen) by making contact with the shields for several seconds each until the shields disappear. The player must then acquire a special cannon and shoot their enemy while it is in their docile state in order to destroy it. The player is also pursued by a lone missile and the enemy can turn itself into a fast-moving swirl entity that will repeatedly charge at the player.
The game is a ROM file only to be played on emulators and is not available on cartridge.
