This game is one of the best games out there, BUT if you have a connection problem you might just throw the game in the trash, activision support is lousy. This game uses a steam account to install the software and if you ever have trouble logging on you'd be better off just throwing the game in the trash instead of going through all the frustration. Steam has no customer support and controls the game online or off. There is no phone number to call and if you try their support..
