2K games has announced the first of what promises to me several DLC updates for the recently released BioShock 2.

“The fans who waited in the snow, rain and cold for the midnight launch of BioShock 2 have spoken and their message is that Rapture still has many fascinating stories to tell,” said Christoph Hartmann, president of 2K. “Downloadable content is a key part of our efforts to continue to entice the fans that have made 2K a household name – we intend to deliver single and multiplayer content that respects and expands upon one of the greatest fictional worlds ever created.”

The first DLC pack is the “Sinclair Solutions Test Pack” and brings an assortment of new features to BioShock 2′s multiplayer mode, including:

• Rank Increase to level 50 with Rank Rewards
• New playable characters Louie McGraff and Oscar Calraca
• 20 new trials*
• A third weapon upgrade for each weapon
• Five additional masks*
  *Some items are only available after a player achieves a rank of 41 or higher.

Looks like a decent assortment, though unless you are really into BioShock 2′s multiplayer mode, this one is probably skippable.

Fortunately, future expansions will update multiplayer, as well as bringing new narrative and gameplay to the single player story mode. My guess is that these will be akin to the Grand Theft Auto 4 expansions (on a much less grand scale), where you are not playing as Subject Delta, but instead playing through smaller episodes in the history of Rapture as secondary characters.

The Sinclair Solutions Test Pack will be on sale on XBox Live and the PSN in March.
