Didn't do much for me tbh and if the last one was anything to go by then this will end up in the bargain bin within a few weeks!!!!
No mate, this looks to be an extremely well made game.
But I do agree with T2D, it has to be your bag and stealth really isn't mine. In a world of FPS, I dare say it's sales figures won't do it justice, but I would like to be pleasantly surprised. I used to love survival horror stuff many moons ago and this looks like they ratchet the tension up nicely. The UK IGN
review explained the gameplay in more detail I thought. Contrary to what Timey said, you cannot even kill the alien once.
If you are old enough to remember the original movie, that table at 5:30 in Timey's link will bring back a few memories.
