I bought it when it came out. Fond memories of real time light sourcing. It was a game that gave me headaches from the dark graphics and no real sense of up and down at times. Also the enemies are really small and the stages are mazes. It was fun and looked nice but I never played it again after selling it. I would recommend it as it was a tough game, similar to the Descent series of shooters. Pay as little as you can for it because it is NOT a pick up and play, thrill in a few minutes, show to my friends kind of game. You really have to sit down and get into it.
