Rob Matheson has released Smurf’n Doom 1.0, which (surprise, surprise) is a port of a Smurf themed mod for Doom. Here are Rob’s comments about the mod:
“This hilarious (and gory) mod is of the shareware version and was created way back in 1995 by a couple of High School students. (Now much older).“
Currently it is only available in DiscJuggler format, you can download it from here. There should be a proper page for the game on DCHB soon.
