There are few games out there with the stature of Doom or Quake, but the Unreal series certainly fits in that group. Unreal, Unreal II, Unreal Tournament, Unreal Tournament 2004-those are just a few of the titles that won awards and helped define online multiplayer FPS gameplay for the PC. And is there any single game engine out there that's as influential as the Unreal Engine? Not only have professional developers used it to produce everything from Brothers in Arms to Splinter Cell to Gears of War, but garage-based modders have turned it into just about anything they could dream up. So what's next for one of the grand old men of shooters? Well, according to the developers, Epic wanted to do something more than just remake UT 2K4 with better graphics.
