2K has let loose with some additional info on the next DLC pack for BioShock 2, the Rapture Metro Pack, coming to Xbox, PlayStation 3 and PC.

Features include six all-new maps, some built from the single-player portion of the game, three new achievements and trophies, and the introduction of the Rebirth system wherein players who reach rank 50 have the option to rank down to Level 1 and receive a special mask.

In spite of some reports that the Rapture Metro Pack would be available this week, 2K has clarified that’s not the case. An announcement on timing is due in the very near future. The DLC will cost 800 Microsoft Points - we've asked 2K to confirm the NZ dollar price for PS3 and PC, but expect it will be about $14.

Two new screenshots have also been released.
