Would you kindly download BioShock DLC on November 20?

The PS3 version of BioShock has a few surprises. Not only does it have a new difficulty mode not found in the original, and a trailer for the upcoming BioShock 2 -- it also grants access to exclusive DLC. The "challenge room" pack will be available about one month after the game's retail release: November 20th. No word on how much it will cost, and how extensive the content will be.
