Star-Ship Wolfenstein is a mod for shareware Wolfenstein v1.0, made by The Unknown. Its files date to July 1992.
The mod also fluctuated as SSWolf, though the abbreviation has nothing to do with the Schutzstaffel.
A very early effort in new maps as well as graphics, a space theme is evident in the mod, meant to take place on a starship. Two levels can be finished, with the third level being inaccessible due to end game triggers rather than an elevator being used on level 2.
