Friedl 3D is a map set for shareware Wolfenstein, released on August 15, 2004. It was made by Friedl.
8 levels are featured, large in size and very well decorated.
The end jump features a locked door nearby and gray slime textures á la Episode 2, suggesting that Friedl had a full map set in mind.
This was not the case, as this set was the author's only release.
