"For every choice, there is an echo. With each act, we change the world. One man chose a city, free of law and God, but others chose corruption and so the city fell. If the world was reborn in your image, would it be paradise or perdition?". ―Sofia Lamb. BioShock 2 is the sequel to BioShock, and is designed to continue the grand storyline of the underwater metropolis, Rapture. It was released on February 9, 2010. The Mac OS X version of the game was published by Feral Interactive and released on March 29, 2012. BioShock 2 capitalizes and improves upon the high-quality effects, unique gameplay elements, and immersive atmosphere that defined the first game. 2K Marin was the development team for BioShock 2, continuing the work of Irrational Games, which developed the first game. Initially, a spokesperson for 2K Games stated that the "Sea of Dreams" subtitle had been dropped. 2K later stated that the subtitle was the title of the first teaser trailer, and not a subtitle for the game.
