Either buy FEAR 1 & 2 or Metro 2033. I didn't like the 3rd one but you might. I think the FEAR pack is 10 bucks and it comes with all of the games. Just buy that and give it a go. --- Calling me an elitist is actually a compliment.
Metro was awesome. Though I bought Fear collection because 3 games for 10$ is awesome. --- http://backloggery.com/legendaryhero99 When you do things right, people won't be sure you've done anything at all.
