Dynamite bombs cause heavy damage to every target on the screen, both enemy and friendly, and a special machine gun power-up allows unlimited ammunition and an increased rate of fire for 10 seconds.Įnemies attack with gunfire, knives, grenades, mortar and bazooka rounds, and missiles all visible incoming projectiles can be shot out of the air.
The player begins with a limited supply of ammunition and grenades, but can find more throughout the game, either openly displayed or revealed by shooting crates and barrels, coconuts in trees, and animals such as pigs and chickens. In order to complete each stage, the player must shoot a required number of soldiers and vehicles (trucks, boats, helicopters, armored transports), as indicated by an on-screen counter. Pulling the trigger allows fully automatic fire, and pressing a button near the muzzle launches a grenade with a wide blast radius that can hit multiple targets. A geared motor inside the casing simulates the recoil when the player fires the weapon. This, in turn, is mounted on top of a square base covering the pivot shaft which allows players to swivel and elevate the "gun". The game utilizes an optical controller housed inside a gun assembly scaled after and which bears a strong resemblance to an Uzi submachine gun. This is one of the first shooter games to feature a storyline. For example, after the Jungle stage is completed, Adams interrogates an enemy soldier and learns the location of the concentration camp where the hostages are being held. The game is divided into six stages, each of which advances the story when completed. The game is viewed from a first-person perspective, and is on rails, with the screen scrolling horizontally through the landscape. Assuming the role of Special Forces Operative Roy Adams, the player attempts to rescue five hostages who are being held captive in enemy territory.
