You command two space ships in the middle of an asteroid field and must do all you can to keep them alive.

Prevent your ships from being destroyed by following them with your fingers on your touch screen. Be careful, when you remove your fingers the shields go down and you can be destroyed by an asteroid! As your ships move, their mass decreases so that they begin to move and bounce faster and faster.

Lower your shields temporarily to collect power-ups which can boost your score, slow asteroids down, raise your ship's mass, and more.

Your goal is to stay alive as long as possible.
