Maybe you're a little rusty on your BioShock lore. Perhaps you're looking for a refresher before BioShock Infinite's March release. Or – gasp – you've never played Irrational's critically acclaimed game and its follow-up. Whatever your motivation, 2K Games has announced that it's releasing the BioShock: Ultimate Rapture Edition, a budget-priced bundle that includes the first two games and more.

We'd heard rumblings about this one months ago, but now it's official. In addition to the pair of games, 2K says the Ultimate Rapture Edition includes a host of add-on content:

• Plasmids Pack: Includes four additional Plasmids and Gene Tonics – Sonic Boom, EVE Saver, Vending Expert and Machine Buster – for use in BioShock.
• Challenge Rooms Pack: Previously exclusive to PS3 and now available for Xbox 360 for the first time, the pack tests the player’s mettle by requiring them to utilize the skills learned while traversing the halls of Rapture to survive three separate puzzle rooms in BioShock.
• Sinclair Solutions Tester: Contains a number of customization features that allow players to further their character’s development in BioShock 2 multiplayer modes and provides a deeper multiplayer experience.
• Rapture Metro: Includes six additional multiplayer maps, an additional multiplayer gameplay mode and a rank increase to level 50 for BioShock 2 multiplayer.
• The Protector Trials: Features frantic combat and fast-paced action designed to push players’ mastery of weapons and Plasmids in a BioShock 2 single-player experience spread across six maps.
• Minerva’s Den: A substantial narrative experience that puts players in the role Subject Sigma and introduces new characters, locations and mystery to the world of Rapture in BioShock 2. Set in a new environment, Rapture Central Computing, Minerva’s Den adds a gripping new storyline to extend the BioShock 2 experience.
