Wolfenplum is a map set for shareware Wolfenstein. It was uploaded on the Dome in March 2000, but was listed as being an older set. Authorship is unknown.
It features 10 levels, though the secret level is pretty much non-existent. Most levels are large in size.
All files were included in the download, including a VSWAP file that appears to have been changed in 2000, though no new graphics appear.
