Destroy all these flying saucers before they destroy you or before they capture all the human cities on planet earth!
There are two levels : earth and mars, the waves of UFOs are infinite and of course it's more and more difficult!
Try to win the real challenge of the game : to get all the game's achievements with Apple's GameCenter ! (to which you will have to be connected)
The game has just been released (end of july).
More to come in the next updates (new achievements and surprises!)
