The game primarily plays as a side-scrolling brawler, but certain stages switch into shooting segments that change the pacing. Players fight through streets and indoor areas, clear waves of enemies, collect weapon upgrades, and use character-specific special attacks to escape bad situations. Success depends on managing crowd control, avoiding projectile-heavy enemies, and adapting quickly when the game shifts into different play modes.

Karl

One of the three selectable heroes, built as a balanced fighter with straightforward close-range combat.

Garth

A selectable hero with a heavier offensive feel, suited to players who prefer direct pressure.

Sheena

A selectable hero with a more agile style, useful for quick movement and reactive play.

Deal with ranged enemies first so they do not force you into bad positioning. Save screen-clearing specials for emergencies, crowded rooms, or dangerous enemies rather than using them immediately. In shooting sections, focus on small fast targets before larger threats. In co-op, split responsibilities so one player manages crowds while the other handles priority enemies or bosses.
