Space Loons for Wolf 3D Shareware is a Shareware Wolfenstein 3D mod by Dr. Von Loon released in November of 2006. A full 60 level version for registered Wolfenstein 3D was also subsequently released.
Space Loons purchase a time travelling device at a yard sale and attempt to travel back in time to alter the outcome of World War 2. Instead, however, they show up outside of our solar system in the year 1946. The player is tasked with boarding their TimeStation and put an end to their operations.
