BioShock Infinite Burial at Sea Episode 1 DLC is now available for download across the PC, PS3, and Xbox 360 platforms, and developer Irrational Games has just posted the launch trailer for the new expansion.

BioShock Infinite delighted millions of fans from around the world back in March and, since then, developer Irrational Games has been working hard on new content for the title.

The first episode in the two-part Burial at Sea add-on is currently being rolled out for PC via Steam, PS3 via PS Store, and Xbox 360 via Xbox Live Games Store.

In order to celebrate the release, a special launch video has just been posted by Irrational and you can check it out above.

In case you're unaware of the premise, enjoy the description below.

"On the eve of Rapture's fall from grace, Elizabeth enlists Booker DeWitt's services in locating a lost girl. Who is this girl Sally, what does Booker know of her supposed fate, and what is Elizabeth's connection to this mysterious child? Find the answers to these questions and more in this new addition to BioShock Infinite, built nearly from scratch by Irrational Games."

Burial at Sea Episode 1 is available for a price on all platforms, but Season Pass owners get it for free.
