The player assumes the role of an unnamed commando trying to destroy several enemy military bases. The player's character is seen from behind and initially starts behind a protective wall (the wall can get damaged by enemy fire). The player must use a limitless ammunition gun and a limited number of grenades to fend off enemy troops and damage the base. At the successful completion of a level, all the buildings onscreen collapse and the player progresses to the next stage. Power-ups appear from time to time, being released from objects destroyed onscreen. Some power-ups give special weapons, many of which are formidable. Two players can play this game, cooperatively, simultaneously.
