E3M1: Gatehouse is the first map in episode The Evil Unleashed of 2002 A Doom Odyssey. It was designed by Sam Woodman (Metabolist) and uses the music track "Runaway Train" by Paul Corfiatis. In the 10th anniversary edition a couple of geometry modifications were applied but the things population was left unchanged.
