Here's a new marketing approach from Irrational Games.

Its new DLC for BioShock Infinite, called Burial at Sea: Episode Two arrives later this month. Irrational recently announced its own closure as founder Ken Levine sought a smaller, more focused new operation.

And so this promo doubles as a straight-up declaration of the new content's benefits, as well as a resume for the many people who worked on the game's creation. Interviewees' contact details are presented as well as the specifics of the work they contributed.

Burial at Sea: Episode Two puts players in the role of Elizabeth as she explores the world of Rapture during its fall.
