this game has the most immersive game play ever. t doesn't need fancy mechanics, the way the story is told along with the soundtrack give you a feeling of mystery and horror that also makes you feel alone on a alien planet but not so alone that it gets boring there are other things there...
you just have to go deep enough to find them.
this game has a amazing sound track along with some of the best graphics i cannot believe i was alive to see a game be made that was this good. the mystery lore and animals along with the twists and turns of this story make it a experience i will never forget.
