Bioshock Infinite - the fantastic first-person shooter swansong from Irrational Games - has been a huge hit, and Mac users have been able to join in the fun thanks to the efforts of Aspyr. Now the company has released the second part of downloadable content (DLC) for the game - Burial at Sea - Episode 2.
Bioshock Infinite takes you to an alternate version of the early 20th century, where scientists and engineers have been able to create a massive floating city. You've been hired to rescue a young woman named Elizabeth; both she and the city's protectors harbor secrets that can affect the very nature of reality.
Burial at Sea returns you to the underwater city of Rapture, scene of the first game. Elizabeth explores Rapture during its fall, and attempts to Sally, an orphan befriended by Booker DeWitt, protagonist of Bioshock Infinite.
