A press release from publisher 2K Games confirmed the release date.

The challenge rooms encourage players to solve puzzles while a Portal-esque timer runs in the background. "Challenge rooms retain the flavor of Rapture, but they're not trying to retrofit new story or new levels into the original game," said a 2K representative back when the rooms were announced.

The soon-to-be-patched PS3 edition of BioShock lands next week.
