Players have a limited reserve of energy to use when playing, and all activity drains energy, including running and throwing. Each group has a unique set of powers, such as cloaking, which drains energy even faster. Players can regain energy by various actions, such as successfully catching a thrown ball.
The ball can be thrown in several ways. Throwing the ball while running causes the ball to move in the direction faced. Throwing the ball while standing still allows a 360 degree aim, with better tracking. Throwing the ball while jumping increases the force at which the ball hits.
