Grossed Out is the first mod released by John Bucksnort. It was released on April 22, 2000.
It is based on shareware Wolfenstein, and features none of the Spear of Destiny or DOOM elements otherwise prevalent in the bulk of Bucksnort's work.
All files are included in the download, but only the maps were changed.
Level 10, the secret level, was made by Brian Lowe.
An SDL port was released on May 6, 2012.
