Using stolen blueprints, a south-american government has built a super weapon in a lab in a jungle. This weapon, the Positronic Gun is a danger to world peace and must be destroyed. Three mercenaries, Charlie Montinni, Humphrey Stallone and Billy von Pettet are sent on this dangerous mission.
The game uses a top-down view. It can be played by up to three players cooperatively. The player must navigate through dozens of jungle screens before reaching the Positronic Gun. Weapons include a rifle, proximity mines, grenades, a knife and artillery strikes.
