Doom Universal Tour is a mod for Spear of Destiny, made by Ian Summerfield & Mega Luigi. It was released on April 3, 2005.
It features 5 levels, and carries the influence of DOOM as many textures and guards are used from that game.
The EXE is that of Beyond Mutantstein Special Edition, and though credited in the Read Me, the respective authors were not asked by Summerfield if they would allow usage of the material. This made news on DHW for a short while.
