Aurora Feint 2: The Arena [iPhone]

Slower game
In versions before v3.1, play music while the game is running with the application's sound settings turned on. It will be as if the Time Stopper power-up is being used constantly. In v3.1 or later, hold one of volume buttons during game play to get a similar effect.

Audio Slowdown Exploit
Playing music on your iPhone or iPod Touch while using this application with the application's sound settings turned on causes massive slowdown equivalent to that gained through using the Time Stopper power-up. Note: works best before version 3.1, which was released largely to stop abuse of this glitch. After version 3.1 a similar (although lesser) benefit can be achieved by holding down one of the volume buttons during gameplay.
