The Wolfenstein SS soldiers, based on the Schutzstaffel enemies from Wolfenstein 3D, only appear in the two secret levels of Doom II, which are based on Wolfenstein 3D maps. They have 50 HP and are equipped with a machine gun. These soldiers speak the same German lines as their Wolfenstein 3D counterparts, but with a different, higher pitched voice. Also, unlike their tough, deadly equivalents from Wolfenstein 3D, Doom's SS soldiers are notoriously inaccurate, hitting the player or other monsters with the same likelihood. The SS soldiers do not appear in the German release of the game, since the the Wolfenstein 3D themed levels have been omitted owing to the Nazi content they feature. These levels are also missing from the Playstation version of Doom, where different secret levels are used in their place, but are featured in the GBA release of Doom II.
