I remember spending many nights up late in the mid 90's playing this on our first family PC. Lot's of great memories with this game, this was the first shooter I owned and I remember being terrified of the Nazi shouts and the skeletons w/ blood on the ground yet I could not stop playing. This along with Warcraft 2 are some of my first PC gaming memories. Great video guys, glad I came across it.
If it works the way it did in the dos version you actually have to go to the menu to increase or decrease the screen area. Doom used the + and - keys to change it during the game.
@Vilestorm @GunnyHath Ah you could be quite right, I really didn't play Wolfenstein much, I was a Doom/Quake/Duke kid.
