Players control Billy or Jimmy through side-scrolling stages, using punches, kicks, jump attacks, throws, and found weapons to defeat enemies. Unlike earlier entries, this game adds a shop system where currency can be spent on characters, items, and upgrades. Progression is stage-based across multiple regions, with the pace shaped by resource management, enemy waves, and occasional character-switch mechanics depending on version.

Billy Lee

One of the Lee twins and a main protagonist, specializing in close-range combat and weapons.

Jimmy Lee

Billy’s twin brother and one of the primary playable characters.

Marian

An important recurring character in the series, tied to the brothers’ quest.

Save currency for useful characters and essential items rather than spending it early. Use jump attacks and weapons to control crowds, especially in narrow spaces where enemies can surround you. In boss fights, keep moving, watch for attack tells, and punish openings with throws or quick combos.
