Wolfenken is a mod for registered Wolfenstein, made by Kenny Roels, who also went by the name RKS Kenny. It was uploaded on the Dome on May 27, 2002 along with Roels' two other mods, Dark Dungeon I & II.
Creation and initial release may have been September/October 2001. Roels had his own Wolfenstein site which hosted mods, and this is where the mods were first located before being uploaded on the Dome.
The mod uses sounds unique to this mod, including all guard sounds. One death scream is taken from a song by Prince, Sexy M.F. Most sounds are humorous, with many death screams being silly, or speech mangled via a sound editor.
It follows an episodic flow, though all episodes are simply titled "Play it".
Sprites have been borrowed from other games (e.g. a health vial from Heretic, as seen on the screenshot).
Before being ported to SDL in December 2013 by Andy Nonymous, certain parts of the mod were inaccessible due to the high presence of Hitler ghosts and objects, with frequent crashes due to the "No free spots in objlist!" bug.
Kenny Roels had his own Wolfenstein site which hosted his own mods, other mods, and editors (link below). Roels also used photos of himself as textures in the mod. Other textures remain unique to the mod, e.g. Pharaoh textures, concrete slabs, outer space designs and tweaks to doors.
