Oh my days, it's dirt cheap. My friend bought it for me for 2.50 EUR, but it's £3.75 in england. I'm guessing it's $2.50.
 
Huge download, 12gb, but it's a pretty cool game though not worth the full price they were asking for it in my opinion, but for 2.50, you can't go wrong.

An old post, I know. But I just wanted to point out that they're having this game on sale on GamersGate this week.

75% off, a total of 2.48 €. That's a pretty good price I think.
