The game uses a side-scrolling run-and-gun structure with single-player progression through mission-based stages. Players move left and right, crouch, jump, and fire in multiple directions while collecting weapons and power-ups. Levels mix standard combat with heavier set-piece encounters such as alien nests and large boss battles. Progress is stage-based, with checkpoints or respawn points depending on the section.
