There are many games well-suited to Apple's iPhone. SimCity, for one. Advance Wars, that would be another (HINT). But first-person shooters? Hrm. But hey, maybe Prey - of all games - can change that.
Yes, Prey. You know. American Indians, spike machines, assholes on the wall, that Prey. Somehow, somebody, somewhere thought porting the game to the iPhone would be a good idea, so, uh, here we are.
