There's a survival horror game on Steam called Outlast. It's $20. Pretty well done. You play an investigative journalist checking out an old insane asylum. You have a camcorder that has a night vision mode that eats through batteries but allows you, of course, to navigate dark places. Basically your job is to explore, record, and evade. You don't fight, you hide. Parts of it are creepy as fuck. Check out the Steam page or maybe Google it for gameplay vids.
Wait for the patch. Not the next one, not the ones they promise every week, that one patch about 6-8 months down the road that finally fixes everything shortly before DLC makes an appearance.
But man, if they had actually fixed the performance issues, this game would have been an epic release. I see what they were trying to do with the campaign map, and it would have been sweet if it worked, but it didn't, and they didn't have a plan B, so the campaign map takes way too long to update and you spend more time waiting for your next turn than actually playing.
They for sure got the real time battle part working though. Probably the best in the series, yet.
