This game is a masterpiece of horror gaming. It is the Aliens of video games.
I don't think I've played anything scarier. Sure, it's not a slasher, it doesn't have a lot of the horror shticks, but this is brilliantly scary.
There is nothing freakier than that crazy multi-voice thing whispering to you after having some ugly critter jump you and you're almost out of hit points and ammo and already really jumpy.
Newer survival horror games don't really have anything on this game. This game is the acid standard. If you like scary games, play this NOW.
In addition, the gameplay is awesome too. There are role-playing aspects as you develop skills and find clues and enhancements. You do all this on a big scary ship that just scares the s$#t out of you.
