Black Magnetic is one new level for DooM II with new monsters, textures and weapons. It was built for the Doomja-Vu contest started by Tormentor667 on the Realm 667 forum. NMN Corporation is carrying out prohibited experiments with demons genetic material in a laboratory disguised as a storage installation. Space Marines send you to terminate such activities. Good luck. I tested this level with GZDooM version 1.8.2 and 2.1. I don't know if it works with other versions or with ZDooM. You
