W3DXLV11 is a map set for shareware Wolfenstein 3D, released in the second half of 1992. It uses version 1.0. Authorship is unknown.
It aims solely to replace E1M1, and bungles even this simple job, as the new map uses pretty much the entirety of the vanilla design with just some additional areas.
This set also appeared in the Wolfmaster map pack, and was duplicate twice; sets EE, TT and UU are essentially W3DXLV11.
