OPERATION WOLF NINTENDO NES

Operation Wolf is an arcade game from Taito. It's essentially a bitmapped rail-shooter, where you hold the gun and shoot just about anything that moves, while conserving your ammo and grenades. Shoot ammo/grenades and healing items around the screen to "pick them up." Your main machine gun can kill anything if you hit it enough times, but you can also use the grenade launcher for really deadly targets like helicopters or armored cars. You can pick up a machine gun that will allow you to fire faster for a few seconds.
