Mademoiselle Blanche de Glace (an internationally acclaimed actress) and Zigo d'Acosta (a great sailor) would like to play Bioshock 2 with you.

We procured a few extra download codes (for Xbox 360) for these two multiplayer characters, and we'd like to give them away to a few Bitmob community members. Here's what you need to do:

1. Make sure you're registered on Bitmob with your real first and last name, as well as your real email address.

2. Go on Twitter and Tweet: "I want free Bioshock 2 DLC from @Bitmob http://bit.ly/dyrhAV"

3. Then come here and post a link to that Tweet in the comments below.

We'll pick the winners at random tomorrow morning and send them the code for downloadin'. Good luck!
