TapTap Revenge, which is the iPhone/iPod Touch's equivalent of Guitar Hero, just released a Nine Inch Nails version of the game. The game soundtrack includes 13 tracks from NiN's last two releases The Slip and Ghosts I-IV.

Aside for being a highly addictive game, Tapulous is giving away floor tickets for every NIN show between 11/8 and 12/12. There is also a grand prize of a Les Paul guitar signed by Trent. To enter, you need to submit a score of over 150,000 points on any track in the game. (I haven't personally broken 100K yet).

The Nine Inch Nails version of TapTap Revenge is available through the iTunes App store for $4.99
