Epic Megagames and Digital Extremes updated their Unreal Tournament franchise with Unreal Tournament 2003 in (somewhat confusingly) late 2002. The long-awaited sequel used the revolutionary new Unreal II graphics engine, raising the bar once again for quality and detail for first person shooters.
Although some hardcore fans of the original Unreal Tournament objected to its clear inspiration from Quake III Arena, Unreal Tournament 2003's frenetic gameplay, spectacular level design, and faithfulness to the franchise made it an instant and runaway best seller.
