The game uses a side-scrolling perspective. Players move through stages from left to right, defeat groups of enemies, and advance through brief cutscene transitions and boss encounters.

Billy and Jimmy can strike, jump, throw opponents, and use dropped weapons. The campaign is designed for one or two players, with progress centered on clearing a fixed sequence of international stages and defeating the final opponents.

Stay near the edges of enemy groups rather than allowing attacks from both sides. Prioritize enemies carrying weapons, since their attacks can quickly interrupt your movement.

In two-player mode, separate targets where possible and avoid striking your partner during crowded encounters. Save safer positioning and repeated jump attacks for bosses instead of rushing into the center of the screen.
