Fuck them. I will not spend money on what is essentially a part of the game that should've been included on release, but was likely left out due tho their rush to beat COD to the shelves. It's less than a month since release and this is a clear rip-off. Over and above, you are also going to paying for a few game fixes as well, due to the game not having been polshed before release.
I say again, fuck them. This is only going to serve to alienate the community even more. Way to lose customers to COD you rocket scientists.
