Project Übermensch is a mod for shareware Spear of Destiny, made by Bernt Hansen. It was released on November 13, 2003.
It features 2 levels and a handful of changed graphics. Though it was mentioned that a handful of levels would follow later, this was never realized.
Being only a demo with new maps and graphics, it is playable in SDL.
