Looks alittle steeper then modern warfare 2. I got no worries but maybe some of you do. Also if you didn't know it has been confirmed that this will be on steam and will use VAC, steam friends, steam cloud, and I also believe steam groups for the clan tag. the clan tag is unconfirmed but steam and vac is.
