Rapture Metro Map Pack
is the second DLC for BioShock 2
and adds six new multiplayer maps. Some are levels from the game's single player campaign that have been redesigned for multiplayer. It also adds three new achievements (Xbox 360 / Windows), a new "Kill 'Em Kindly" melee mode where every blunt object is a golf club, and the Rebirth Feature for players who have reached Rank 50.
