The mental institution is pretty large and you will be doing a lot of exploring as you uncover what went on here. This eats the batteries so you have to be on the lookout for them and decide when you really need to use your night vision. Outlast has many areas without lights so you have to use night vision on your camera. He is only armed with his camera and this is what you need to use for most of the game. Miles is just a regular dude and he cannot fight the evil that is in this place. This is a first-person horror game, but you are not some kind of powerful character. These are the three choices that you have in Outlast. It does not quite stick the landing, but even with the not so hot ending, it is a great story. Outlast tells a very interesting story and one that keeps you on the edge the whole time. There are mutilated bodies, the place is a mess, there is some kind of cult leader, a messed-up doctor and a strange thing called The Walrider that everyone is scared of.
