It is absolutely amazing. I played the early alpha a few months ago, but it is much smoother now and much more balanced. The three new maps (Shahallah Valley, Al Khafji Dock and Lost Village) are simply superb. The Dock one is great - the US forces have to use those commando dinghies to cross a wide stretch of water to reach a docked freighter and dockside - all the while being shot at by the Iraqis. Just go as an Iraqi HMG PKM guy, lay down on the deck of the ship and blast away at the incoming commandos.
Lost Village is a large town where every building is open to be entered. The US has to chopper in their guys by black-hawk dodging fire from the new Stinger armed bazooka guys. The Stinger rocks BTW - 2 to 3 stinger guys can take out a Blackhawk in one shot.
