Priced at 400 Microsoft points, 2K Games have released the first DLC to the seminal Bioshock 2.

With the focus very much on the customisation of your character's development in Bioshock 2's multiplayer modes, the pack enables you to increase your rank to level 50.

The Sinclair Solutions Tester Pack also gives you the option to add a 3rd upgrade to your weapons.

Also included is the option to play as two new characters (Louie McGraff and Oscar Calraca) and the addition of 5 new masks.

It should be noted that some items are only available after a player achieves a rank of 41 or higher, making the add-on a worthy purchase if you are looking to progress from that level.

However, the new characters, masks and weapon upgrades are available to all.

The Sinclair Solutions Tester Pack is the first of several add-ons planned for Bioshock 2 in 2010.

2K Games have promised that the future DLC will expand both the multiplayer mode and the single player campaign, fleshing out the tragic fall of Rapture.

We'll be sure to have full coverage once more details are announced.
