The Crumbling Reich Part 1 is a map set for shareware Wolfenstein, made by Games from the God. It was posted on the Wolfenstein 3D Dome on March 24, 2000 though the set was most likely made between 1993 and 1995. This can also be evidenced by the fact it uses shareware Wolfenstein v1.0 rather than v1.4.
The set includes ten levels and minor graphics changes, mainly in the form of written messages on the walls. Virtually all ten levels use primarily the gray stone texture.
