Wolfenstein SS

The Wolfenstein SS (also referred to as the SS Nazi or Wolf3D Guy) appears only in the two secret maps of Doom II, MAP31 and MAP32. Wolfenstein soldiers fire bullet weapons, much like the former humans, however since their sprites were taken from Wolfenstein 3D they only have one viewpoint. Thus they always appear to be facing the player.

The soldiers drop an Ammo clip upon death. Their wake-up and death sounds are spoken in german and are "Schutzstaffel" and "mein Leben!", respectively. "Schutzstaffel" translates to "protection squad" and "mein Leben!" to "my life!". The Schutzstaffel is the German name for the SS during Hitler's tenure as leader of Germany, but that's a whole other bucket of fish.
