Here, you play a lone gunner in an orbital turret, defending Earth from an onslaught of meteors. The gimmick of this game is that you turn the turret by turning yourself -- your movement is detected by the phone's digital compass. As you turn, you can see the sun, moon and stars pan from side to side with your real-life environment.

There's no vertical aiming, as long as you're looking in the right direction you get a target lock, then just tap the screen to fire. The game comes with a warning that it can cause motion sickness. You'd be wise to heed this, given how addictive it is.
