This game has a pretty good multiplayer, even without the online play.
There are a couple of different people to choose from when selecting your team. There are two teams each consisting of three people. So if you and the rest of the Alpha team should die, you take control of the Bravo team to complete the remainder of the mission.
The sound is just like any other war game, people yelling, monotonous gun fire and team members talking over the radio.
In conclusion this game is completley average. Nothing special apart from a few good times playing multiplayer.
