Operation Wolf (Japan, rev 2)

Operation Wolf is a light-gun controlled shoot-em-up in which the player takes on the role of Special Forces operative 'Roy Adams' and must infiltrate and capture six heavily fortified bases, with the ultimate aim of rescuing five trapped hostages and guiding them to safety.

In order to complete each stage, the player must shoot as many enemy soldiers and vehicles as that stage requires. Enemy soldiers can throw hand grenades and knives, while enemy vehicles can shoot missiles and launch rockets. The player's ammunition and grenades are limited, but can be stocked up by shooting barrels and crates. Occasionally a high-powered machine gun power-up appears, allowing the player's gun to have unlimited ammo and an increased rate of fire for 10 seconds. Completing the 'Powder Magazine' stage fills the player's ammunition and grenade supplies to maximum.
