BioShock Infinite is a first-person shooter video game, and the third game in the BioShock series. Previously known as "Project Icarus", it was developed by Irrational Games for the Microsoft Windows, PlayStation 3 and Xbox 360 platforms. BioShock Infinite is not a direct sequel or prequel to previous BioShock games, taking place in an earlier period of Dieselpunk and different setting and not having any major horror elements, though it features similar gameplay concepts and themes, and near the end Booker visits Bioshock's underwater city known as Rapture. The player controls a former Pinkerton agent, Booker DeWitt, as he attempts to rescue Elizabeth Comstock trapped aboard the collapsing air-city Columbia in 1912.
It was released worldwide on March 26, 2013.
