A puzzle-solving experience
Pseudoform was initially started by Nullsquared as a tech-demo for showing off portals using the OGRE3D graphics engine. It's going to be a first-person puzzle-solving game.
As opposed to first-person shooters, it's going to be all about making your brain melt as you try to solve the various puzzles. "Pseudoform" means "False Shape" which is the general idea of this game in regard to the community involvement.
