The DLC, dubbed "The Faction Pack", includes three new single-player missions that assign players as different characters from each warring faction of the game. The playable characters are a special detachment sniper from the Red Line, a Reich "Heavy" unit, and a Polis ranger in training.

Players will be checking out previous locations from Metro 2033, using new weapons and combating returning mutant types from the original game. The DLC will be out on July 16 in North America, and July 17 for the rest of the world on Steam, Xbox Live, and PlayStation Network.
