Played two coops yesterday and it was a blast. I think N44 is too much for this game. The maps are simply to small for everything they've put in. Btw, I've heard a new N44 version is in the making including Russians.
V 2.0. I'm really looking forward to it. N44 is really fun on the larger 3v3 and 4v4 maps. Matches on 1v1 tend to end a bit fast on N44. I really like the N44 unit system, though it tends to get buggy sometimes. BK is less historically centered if you want.
I was actually very pleased with that game, especially with the cops.
I'm not a big fan of it. Technically speaking, it's very good; with the excepetion of the facial animations, they suck. Sad thing is that there's nothing else to do besides the main campaign; once you're through, you're through.
