Surprise! The Rapture Metro Pack for BioShock 2 is debuting tomorrow on XBL and PSN, along with two other DLC packs: Kill’Em’Kindly, where you fight to the death with golf clubs, and a character pack that adds two more characters to the multiplayer lineup.

The Rapture Metro Pack of maps will cost 800 Microsoft points (or $9.99), while the character pack will cost 160 ($1.99). The mode that lets you beat the living daylights out of people for seemingly no reason other than a perceived threat? Totally free! Hooray for small miracles.

The map pack contains six new maps for your playing pleasure (some from the original BioShock), three new achievements/trophies and the “Rebirth” feature that allows your character to be reborn as a Level 1 rank with a special mask.

Check out this trailer for the free DLC coming tomorrow. It might make you want to play golf. Might.
