if you scroll down to the bottom there is a section entittled legacy of kain:canceled sequel with various environtment shots from an aparent build of the game. not sure if its legit just found it screwing around on google but if its real it doesn't bode well. if anyone can tell me who hausmann is that would be usefull.
apparently there is an aaron hausmann who worked on 25 to life as an artist, this being another game with material displayed in the portfolio.
