E4M8: Impossible Mission is the eighth and final map in episode The Search for Stephanie of 2002 A Doom Odyssey, or episode Torment Ultima in the 10th anniversary edition. This is the only level in the megawad that remained almost identical between editions - the only difference is that two shotgun guys (things 259 and 260) were moved 64 units farther from each other. This level was designed by Paul Corfiatis and uses one of the following music tracks: "Gunshot Dance" (ZDoom-only), "Confusing" (ZDoom-only for 10th ed.) or "Eternal sadness," all of which were composed by himself.
