AnandTech has reported that Epic Games, the creators of games such as the Gears of War series, BioShock, numerous Tom Clancy games, and so on, have been able to port their Unreal Engine 3 (the “engine” that runs the games) to the iPhone 3GS and iPod Touch 3G.

The demo is both playable and has a flythrough. It’s using a modified Unreal Tournament level previously shown off at GDC. A virtual thumbstick on the left side of the screen controls your movement, while tracking your thumb in the lower right corner of the screen controls the camera. Just tap the screen to shoot. Mark said this is a tech test bed and they’re experimenting with several different control schemes including ones with tilt…
..It requires OpenGL ES 2.0, so the iPhone 2G and 3G won’t work, nor will the older iPod Touch models. It doesn’t really matter though, this is just a starting point…
Here’s a short demo video:
