Flux was basically a very sophisticated 3D puzzle game involving a salesman in a suit as its main character, that was in development for the Playstation and PC. The player had to find his way through a maze of cubic rooms that could be flipped in 90 degree angles by pushing switches on the walls. The game was in development by Pulse Entertainment and was picked up by Microsoft but canned after awhile for unknown reasons..
