[From NES Warpzone]"I worked on Hellraiser which you know never was released. They [Color Dreams] had the rights to make the game for several years and just sat on it. I don't know why. We were gonna use the Wolfenstein 3D engine for the game. I remember that the progammer on Hellraiser got the graphics in and the monsters working. It was all very bare bones stuff, but it was getting there and looked like it'd be fun. And then it was abandoned again for other titles." [sic] - Roger Deforest
