I downloaded it, and tried it. It's kind of clunky at best. I think I'll stick to CoD:UO for the time being. I found it difficult to distinguish between enemies and teammates, and the UI didn't help one bit. The chat windows and notification of who killed who is WAY too intrusive, and the ammo indicator is way too small, IMO. The compass sucks; there's no other way to describe it. I also don't like the controls, so I had to spend a while re-mapping them. The whole feel of the game is just... odd. I can't hit the broad side of a barn in that game, yet I'm an awesome sniper in others. Since it's free, it's a good deal, but I hope Vivendi plans on issuing some patches to flesh out the game a little better. If that's supposed to get me excited for the single player experience, color me EXTREMELY turned off.
it was okay i hate online though way too hard and i sucked at it so i just played the single player a few times then uninstalled it :\
