Though BioShock games can certainly be fun to play, the titles are lauded more for their story than their first-person-shooting. The two episodes of BioShock Infinite‘s Burial at Sea DLC, then, are much more anticipated than the already-released Clash in the Clouds.

The story DLC will take player back to Rapture, the setting of BioShock and BioShock 2. A teaser mockumentary released last week shows that the characters may play just as big of a part in Rapture as they did in Columbia.

Irrational and 2K today released a five-minute, un-cut look at the beginning of the first episode of the DLC. It shows an alternate-universe Booker as he is approached by the sultry alternate-universe Elizabeth. She leads him on a short tour of a pre-disaster Rapture, complete with bystanders throwing out Randian quips. On close inspection, however, not everything seems perfect and it becomes clear that Burial at Sea might just detail how Rapture fell in the first place.
