Thanks, I picked one up for a gift.
I got the game a while ago for $29.99, and for this price it is a steal. The game has a great atmosphere, and really sets the mood in terms of putting you into the aftermath of a post apocalyptic event.
Everything is good, but the only thing I hated was the shooting/aiming for the game. It just seemed so broken compared to other shooters. Still doesn't ruin the experience, but it would had made the game more enjoyable for me. Bottom line, buy it.
