Sgt. Billy "Big Bang" Blitz
You control Billy Blitz, or Bang as he is known in the American version of the game. From the start of the game, you are on a mission to rescue Professor Plum and save the world from the threat of his Doomsday Device. To accomplish that, you'll have to travel across various routes that are located around Demonhead Mountain.

Bang is a trained member of a special ops team. He is very athletic and can jump tremendous distances and heights. With the aid of some equipment, he can jump even higher and farther. He also carries a weapon with him, his trusty pistol. Each bullet he fires will travel all the way across the screen, and he can fire two such bullets on the screen at one time. It will never run out of ammo. Bang can collect or purchase other more powerful special weapons, but they possess a limited amount of ammunition, and can run out, so save them for special occasions.

Bang has a power meter at the bottom left corner of the screen. In the beginning of the game, it starts out with four bars. After accomplishing certain tasks, or acquiring particular items, his power meter will expand, allowing him to take more damage before collapsing. Each bar does not represent a single hit point, but rather a collection of hit points; Bang can be hit multiple times before losing a bar from the meter. However, if Bang's takes too much damage when his power meter is empty, he will die and the game will be over. You will return to the main menu screen, where you will be given the opportunity to continue, returning you to the map at the last location you visited before you died.

Power Suits
There are four power suits in the game, which you can purchase from a store. Each suit enhances Bang's abilities in a different way.

Force abilities
Once you rescue the Hermit on, he gives you the ability to use Force points to access certain abilities. You must, however, reach a certain number of Force points before each ability becomes available to you.
