Steam is running a promotion on Unreal Tournament 3, enabling all Steam members free access to Epic Games' Unreal Tournament 3 over the course of the weekend.

It's a great time to try out the multiplayer FPS too, with the recent release of the Titan Pack expanding the game with a host of new maps, modes and features. Once the free trial is over you'll also be able to purchase UT3 for the reduced price of £8.39 - the special price is valid until March 14.

You'll find more info over on Steam.
