If you're an older gamer, odds are you fondly remember playing the original Wolf 3D back in the day. Well, Gray Matter Studios brought the characters and setting back to life back in 2001 with id's then state-of-the art Quake III engine. Its sci-fi spun,World War 2 theme really spiced up the single player side of the game, while the real-world art style and snowy Bavarian locations helped ground it into reality. Eventually, a free expansion pack called Enemy Territory (from Splash Damage) was released, giving the game an excellent multiplayer mode, which is still popular today. A sequel to Return to Castle Wolfenstein is in the works now, although details about it are few and far between.
