A port of the arcade title of the same name, Crypt Killer is an on-rails light gun title in the vein of such games as Area 51 and Lethal Enforcers. Seeking the fabled 'Eyes of Guidance,' players embark on a journey spanning six levels, each infested with wave upon wave of monsters, mutants, and undead creatures, all of whom must be summarily dispatched in order to continue onwards. Although initially equipped with a shotgun, players can acquire more powerful weapons such as a Gatling gun, automatic rifle, or grenade launcher along the way. Also in your arsenal are smart bombs that can be utilized to clear the screen of lesser enemies in a single blast.
