I have a great game that you may be interested in for the iPod Touch. It is called Archetype. It is a first person shooter game. If you like those types of games, you'll love this one!
You can check it out on iTunes by going to this link: http://itunes.apple.com/us/app/archetype/id3645049...
Or visit the website: http://villainhq.com
If you purchase the game, contact me and give me your combat-tag. I'd love to kick your butt! ;)
Hope I helped!
