Wolfenstein 3D Classic makes use of an all new control system designed for the iPhone by technical visionary and id Software founder, John Carmack. Choose clever new touch controls or drive with the tilt controls to halt the diabolical Nazi schemes.
And now I'm going to go add some liquor to my coffee as I realize that the game is 20 years old and I was in high school. Yes, go on ahead and start doing the math and start flinging the old jokes. I can take it.
