$12.79 by my math. Oh maybe you got taxed. Also, I paid more for it earlier, played it a little bit, and didn't really care for it. But I'm contemplating picking it up again for this price.
EDIT: After much internal turmoil, I'm gonna have to pass on this one. I don't get a ton of joy out of FPS games that don't involve some type of leveling or advancement. I just get burnt out too quick. Thanks for posting OP.
