Roy Heart has been asked by the CIA to wipe out terrorists who have
taken over a large skyscraper of a major auto-maker in Japan. Using
your fists, knife, or gun, you must use the elevators to travel
between floors and wipe out terrorists that try to bring you down.
Each weapon has its disadvantages. The gun, for example, will only
have so many bullets per life, and the knife will decrease in
strength with every use. During your mission, you will also earn
experience points, and meet and free hostages along the way. These
hostages will heal you, fix your knife, and give you a machine gun.
Some floors end with you defeating a boss, while others end at
elevators. Your must reach the top of the building where you will
confront the leader.
