Map Pack 3 doesn't add any new maps to the game, but does bring two new sought after game modes: Siege and Original Ghost Recon Co-op Mode.

Siege sees one team defending with the other on the offensive. If the attacking team manages to get inside the defensive team's zone and survive for more than five seconds, they win the game.

Original Ghost Recon Co-op mode has you and your team mates facing off against hostile soldiers in enemy territory. Up to twelve players can compete together (3 teams of 4 players) with the aim to reach the extraction point.

In addition to the two new multiplayer modes, the pack also includes the standalone server executable and the server admin console.

You'll find more info on Map Pack 3 along with a list of download mirrors over on the game's official website.
