Played it a bit, up to the part where you activate the four power pod switch and kill the enemies to get the souls and open the door.
Initial impressions are good. Nice solid level design, good ambiance and feel. Nice import of models from different games. Nice features to the game play, but the HUD was confusing until I got used to it. The levels are large and require alot of exploring to find what is needed to progress (I like exploring, but some may not, at least not on this scale). The chainsaw looks really messed up under water. I can jump off the wizard's head to reach areas that aren't supposed to be reached (standing on his head is a good way to kill bees with the chainsaw). The music is sporadic. Initially the game crashed after the first play when I died and tried to start a new game. Then I immediately loaded the game and it crashed and froze my computer. After a reboot I have experienced no more load or crash problems.
