The downloadable content for the PS3 version of BioShock is now available on the PlayStation Network. Priced at $9.99, the content pack includes the previously detailed Challenge Rooms and, as Keith Shetler, Assistant Producer at 2K Boston reveals, the New Game Plus feature. The latter should be no mystery to fans of JRPGs, which often carry such a feature. Essentially it allows you, upon completing BioShock, to start the game over with the exact same character skills and abilities, and even inventory obtained during the playthrough.
