2K Games announced today their plans to quickly update and expand BioShock 2 single and multiplayer modes via several downloadable content packs. The first of these is the Sinclair Solutions Test Pack, available this March from Xbox Live Marketplace (for 360 and PC) for 400 Microsoft Points and from the PlayStation Network for £3.19 (Roughly $4.99, I’d wager). This expansion isn’t the only one, but it is only the first. Additional content packs will become available over the next few months.

The Sinclair Solutions Test Pack contains a number of customization features that will allow players to further their character’s development in BioShock 2’s multiplayer modes and provide a deeper multiplayer experience. The pack includes:

• Rank Increase to level 50 with Rank Rewards
• New playable characters: Louie McGraff and Oscar Calraca
• 20 new trials (available at rank 41+)
• A third weapon upgrade for each weapon
• Five additional masks (available at rank 41+)

The single player experience will also be extended to provide additional insight into the world of Rapture. These packages will include more narrative, new tools and new challenges that extend the lore and fiction of the failed Utopia under the sea.
