The demo was ok. I was kind of expecting it to be much better, but it's just a demo. Kind of disappointed that you don't have much control over what your teammates can do, and I still can't believe after all this time (unless I'm missing something), you can't move your squad members individually. Regardless of where I tell them to take cover, one of the idiots stays out in the open and gets his ass shot. It's a squad-based shooter for crying out loud, and I think it'd allow for much more tactical scenarios if that was possible.
But whatever, it's fun nonetheless.
