It's arrived and looks good, there was a little bit of the gameplay on BBC click the other day, they where saying that although the game has guns it's not really a shooter because the guns can't kill the alien. I think it's going to test you in others ways, it might possibly test your laundry skills as it looks pretty scary in places. 

Here's a vid I found of the very first bit of gameplay.

I remember this from when they were testing it with Oculus Rift. Not sure if I am brave enough 

Found this of Tested guy playing with Oculus Rift. 2 hours long so I've only clicked a few bits.

Found some swear words so NSFC NSFW.

This is a nice vid, explains how the game feels to play.

The more videos I'm seeing the more I want this game  trying to hold out for a Steam discount.

I chuckled and had to share.

hehe, yeah amusing 

Funny 

Scarry.

As I'm typing this Alien Isolation is a huge 75% off on Steam, taking the price down to £7.99.

I'm going to have to grab it 

3.7 hours in and I can confirm that this game is capable of making you change your underwear 

It is a very spooky sci-fi puzzle game.

Can max it out easily on my system, so easy that I have made a 300MHz underclock profile for the graphics card and still achieve a constant 50FPS. Haven't come across any large open spaces so that's probably why.

Would I recommend it ?
For £7.99 ... oh yes 

I've found a mod for this game that takes the graphics up a level, it was already looking nicer on the PC than a console, not to mention the superior frame rate of the PC but this mod lifts it way up there especially the reflections and shadows.
