The final part to BioShock Infinite: Burial at Sea is here with the release today of Episode 2.
BioShock Infinite: Burial at Sea - Episode Two, developed from the ground up by Irrational Games, is the final content pack for the award-winning BioShock Infinite, and features Elizabeth in a film noir-style story that provides players with a different perspective on the BioShock universe.

"I think the work the team did on this final chapter speaks for itself," said Ken Levine, creative director of Irrational Games. "We built something that is larger in scope and length, and at the same time put the player in Elizabeth's shoes. This required overhauling the experience to make the player see the world and approach problems as Elizabeth would: leveraging stealth, mechanical insight, new weapons and tactics. The inclusion of a separate 1998 Mode demands the player complete the experience without any lethal action. BioShock fans are going to plotz."

Episode 2 is included in the Season Pass for the game or can be purchased separately for $14.99 (USD).

This will be (barring some huge, last second change) the final piece of content that will ever be released from Irrational Games.
