New Bioshock Multiplayer DLC Set For March

Even though the multiplayer in Bioshock 2 is probably one the game's weaker links, it seems that 2K Games defiantly isn't giving up on it soon. 2K has just announced that a new DLC pack for Bioshock 2's multiplayer, entitled "Sinclair Solutions Test Pack", will be coming out later in March. The pack is said to include two new playable characters, 5 masks, 20 more trials, new weapons/upgrades, and it will raise the level cap to 50. This entire pack will only cost you $5.00, which doesn't sound bad at all, for the amount of stuff your getting.

Even though this pack is a pretty good deal if your into the Bioshock 2 multiplayer, I won't be picking this one up. The multiplayer still seems like too much of a shoe-in for me to really devote some quality time to it.
How are you guys linking the Bioshock 2 multiplayer? Do you think it helped or hurt the over all feel of Bioshock 2?
