BioShock Infinite DLC, season pass detailed

2K Games has revealed that Irrational is already working on downloadable content for the upcoming title BioShock Infinite.

According to the publisher, Irrational will produce three add-on packs for the first-person shooter, which will provide hours of additional gameplay and include new stories, characters, abilities, and weapons.

2K also announced details concerning the BioShock Infinite Season Pass, which will be available at launch on March 26 and will cost $19.99 on the PlayStation Network and PC, and 1,600 Microsoft points on Xbox Live. It will include all three add-on packs and can be preordered through the game's website or at participating retailers.

According to 2K, those who purchase the BioShock Infinite Season Pass will also receive the Early Bird Special Pack, which contains exclusive gear, including a machine gun damage upgrade, a pistol damage upgrade, a gold skin for both weapons, and five infusion bottles that let players increase their health, shield durability, or ability to use vigors.

Those who preorder BioShock Infinite will also receive the Industrial Revolution Pack, which grants exclusive access to three in-game gear items that boost combat abilities, $500 bonus in-game currency, five lock picks, and the Industrial Revolution puzzle game, which unlocks stories of Columbia and allows players to pledge their allegiance to the Vox Populi or Founders through Facebook.

BioShock Infinite was announced in August 2010 and will ship on March 26, following several delays.

Analysts have suggested that the game would be a significant financial boon for publisher 2K, saying the game could ship 4.9 million copies.
