Operation Eisenfaust: Origins is a Wolfenstein 3D mod developed by Team RayCast and released in 2012. I joined Team RayCast as the lead programmer for a period of time, following the departure of their previous lead programmer. Built on the SDL source port of Wolfenstein 3D, the mod features entirely new levels, enhanced and advanced gameplay mechanics, and a blend of custom and curated artwork, sounds, and music - delivering a completely fresh Wolfenstein 3D experience.
