I first got to know of the game when I played the secret levels in one of the Doom party (can't remember which one it was). You were put into a level with Nazis everywhere shouting "Gestapo" and dying like flies if you shot at them. After you killed all of them and enterd the door to the exit, one of those veeery big rocket-launching monsters came out, leaving only one foot into a puddle of blood. Was scary
Wolfenstein itself is not a very good game I woudl say. Of course it's todays FPS' father, but the colors in the game were all the same and I don't like Hitlers visage...
