I just bought a used 2ng gen ipod touch for 105 very good price, i would have got a 3rd but i dident because the 4th should be comming out this year. Anyway i like FPS are there any, I searched fps and i dident look that far but i saw Modern Combat and i saw that it had online boght that. I realy like shooting aliens are there any games like that or zombies
Doom Resurrection might be good. There aren't many great first person shooters for the iPhone/iPod. You might be better off getting Ravensword, Grand Theft Auto, Jet Car Stunts, or Guerrilla Bob. They're very nice 3D games.
Nova is excellent, but if you happen to get wifi sometime soon, also get cod: zombies and eliminator pro
Trenches is cheap and extremely addictive, and like most everyone else here has said, NOVA is amazing!
It's called a signature, you can write whatever you want on it by going to User CP (located beside FAQ, Calander, New Posts, Search, etc.), then Signature. If you don't have wifi, i'd recommend you get NOVA, Brothers in Arms, Need for Speed: Undercover, Zenonia, Warfare Incorporated, Hero of Sparta, Hybrid: Eternal Whispers, and Payback
I refer you to the list.. http://toucharcade.com/2009/12/25/best-ipod-touch-and-iphone-games-2009-buyers-guide/ All the games listed here are worth a look.
