2K and Irrational Games today released the final DLC installment for BioShock Infinite. The content is the second episode of the Burial at Sea story DLC and wraps up the dimension-spanning tale of BioShock Infinite.

BioShock Infinite: Burial at Sea – Episode Two continues right where Burial at Sea – Episode One left off. The DLC puts players back into Rapture, the underwater city first introduced in the first BioShock game. The content mixes character made famous in that first game with the protagonists from BioShock Infinite in a swirled mix of alternate history and science fiction.

In Episode Two players will take on the role of Elizabeth, as she desperately attempts to save a little sister named Sally. A few glimpses of what the finale might hold were released today via a launch trailer for the DLC:

“I think the work the team did on this final chapter speaks for itself,” said Ken Levine, creative director at 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.”

This final story for BioShock Infinite may also wrap up the entire BioShock franchise. Last month Irrational Games announced that it would be shutting its doors for good.

Instead of leading the large studio, Levine has taken less than two dozen former Irrational employees and founding a “smaller, more entrepreneurial endeavor at Take-Two.” The team that Levine has created will be making smaller titles for a core gaming audience, suggesting that the spectacle that was the BioShock franchise may now be a thing of the past.
