Unreal is a pioneering first-person shooter developed by Epic Games and Digital Extremes and first published by GT Interactive in 1998. It is the very first game in the Unreal series and was the first game to use the Unreal Engine, which was a ground-breaking 3D game engine at the time. Of course most gamers know about the Unreal Engine, and how it continues to innovate now, but this game is where Unreal first started.
