Coldfusion! (sometimes stylized without its exclamation mark) is a mod for registered Wolfenstein, made by Ian Summerfield. It was released on January 10, 2004.
Announced as being the 1st part, a full 60-level version was never made. The 30 levels in the mod are played in episodic flow, as no source code changes are made.
Many graphics have been changed, and feature a slightly humorous, cartoon-like feel in places. The officer has been replaced by a small PacMan ghost, and the dog has been replaced by a brown pig.
It is playable in SDL.
