iSniper Online, which comes up yesterday, is best iPhone game I have ever seen.
I downloaded it to my iTouch and take a try, woo.. , awesome. It 's designed as multi-player on-line game, you can play as a sniper, shooting others just like iPhone game "iSniper" but with real people . I think it is a must try,

You can find it under game/action category, or use this url: http://itunes.apple.com/WebObjects/MZSto...0822&mt=8.,

Have fun.
