2K today announced its intention to expand Rapture as we know it with an “aggressive” downloadable content plan that aims to enhance both the single-player and multiplayer component of BioShock 2.

Due out later this March is the “Sinclair Solutions Test Pack,” which adds to the multiplayer aspect with a host of additional ranks, weapon upgrades, and masks. Slated to hit PC, PS3 and Xbox 360, it’ll run you $4.99 or 400 MS Points depending upon your platform of choice. A brief overview of what is included can be found below.

*        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.

If multiplayer additions aren’t enough to tickle your fancy, 2K further noted that content-starved fans can look forward to more DLC packs in the “coming months,” some of which will impact the dystopian single player experience with “more narrative, new tools and new challenges.”
