AnandTech has an article showing the Unreal Engine 3 running on an iPod Touch and an iPhone 3GS. They also report that it will be seen on another mobile platform at CES. The demo has little point to it right now. There is no score, and only one enemy that spawns again when you kill him. However it is very cool that you can take a game like this and port it to a mobile platform. Since it will be appearing on other mobile platforms, this gives Epic the chance to sell more licenses to the engine, and for us to waste more time have more fun on the ride into work. From the article:

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.
