Pretty crap considering the amount of advertising it has had. If i see that shitty "So we upgraded our own weapons" advert one more time i might actually put a cap in my tv's ass!
Sales should be alright though for a few weeks as it gets discounted. Already £27 at Tesco.
But in the longterm the game will struggle. I thought it might sell on par as KZ2 but it won't get near it with those numbers.
