Counter-Wolf is a mod for registered Wolfenstein, made by Deschard. It was finished in late 2000 and appeared on download sites outside the Wolfenstein 3D Dome before being uploaded, with the author's name being N/A. This may have occurred in the wake of a different CounterWolf which saw the light of day in 2003 and was authored by Ryan King. A lot of chronology and download links have been confused in this process.
Deschard's Counter-Wolf features 20 levels, playable on episodes 1 and 2. Weapons are all new, and one enemy has been changed. There is also a handful of new textures. Otherwise, most Wolfenstein graphics have been kept.
The mod uses the Wolfenstein 3D v1.1 EXE but can be played in sourceports as no coding changes were made. The download is a self-extracting EXE.
