At the end of the final stage, the player confronts an enemy general before being picked up by the extraction chopper proceeding to the final escape sequence.

NES version
Unlike the arcade version, the NES version is single-player only. The premise of the game remains the same, but the controls are changed due to the lack of a third action button. The jump kick is performed by pressing punch and kick simultaneously (B and A), while the back-punch is performed by holding the d-pad on the player's opposite direction and pressing B at the same time (the headbutt is the only combination attack removed in the NES version). However, the player has the ability to pick up and use hand grenades (which were only used by enemy characters in the arcade version) during the boss encounters against the helicopter in Stage 1 and the tank in Stage 4. There are also new enemy characters (such as frogmen, shotgun wielders, and a fat strongman), as well as a new final boss.

There are also huts and rooms where the player can obtain power-ups by defeating the enemies inside. The power-ups consists of a full life recovery, a brass knuckle that increases the player's punch strength, and an armor that makes the player invulnerable to gunshots and knife throws.
