This is a two player game where you try to make the other player lose all their lives. Every turn you have 3 actions. You can move, pack, or throw. Each of the actions cost 1 action point. To move, you type in "Move" then push the arrow key according to the way you want to go. Pack, is the way you collect ammo. When you type in "Pack" you get one ammo. When you type in "Throw" it will use up one of your ammo points. After typing it in, use the arrow keys to tell the ball which way to go. The final action is a shield generator. When you type in "Build," you use the arrow keys to decide which way the shield will be on. Players can pass through it, but balls cannot.
