The ONLY reason I gave it 4 stars is because I can't give it 4.5 on GOG. This game is thoroughly unpleasant, so it's not for everyone. The atmosphere is more oppressive than any 3D big-budget horror game I've played since the early Silent Hill days, which is no small feat. If anyone ever played Sanitarium from back in the day, this should strike a chord or two. I really can't say enough good about this game, as sci-fi/horror is probably my favorite genre of anything. I'm bummed that I'm just NOW find out about this special edition with the soundtrack and some bonus stuff, so I GUESS I'll just buy it again.
