is a light gun shooter arcade game developed by Taito and released in 1987. It was ported to many home systems. The game was critically and commercially successful, becoming one of the highest-grossing arcade games of 1988 and winning the Golden Joystick Award for Game of the Year. Operation Wolf popularized military-themed first-person light gun rail shooters and inspired numerous clones, imitators, and others in the genre over the next decade. It spawned four sequels: Operation Thunderbolt (1988), Operation Wolf 3 (1994), Operation Tiger (1998), and Operation Wolf Returns: First Mission (2023). Gameplay Assuming the role of Special Forces Operative Roy Adams, the player attempts to rescue five hostages who are being held captive in enemy territory. The game is viewed from a first-person perspective, and is on rails, with the screen scrolling horizontally through the landscape. The game is divided into six stages, each of which advances the story when completed. 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 uses an optical controller housed inside a gun assembly which bears a strong resemblance to an Uzi submachine gun. This, in turn, is mounted on top of a square base covering the pivot shaft which allows players to swivel and elevate the gun. A geared motor inside the casing simulates the recoil when the player fires the weapon. 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. 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. 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. 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. Enemies attack with gunfire, knives, grenades, mortar and bazooka rounds, and missiles; all visible incoming projectiles can be shot out of the air. The player has a damage bar that slowly fills due to enemy
