Andrew Ryan built the underwater city of Rapture on the ideal of the individual striving for achievement. In 2007, BioShock examined and repudiated that philosophy, depicting Rapture as a city doomed by its lack of a moral center. But Rapture did not die with the dream. BioShock 2 returns us to it, ten years after the events of the first game. The city is still inhabited by the crazed splicers, who modify themselves with fantastic powers using plasmids and the mysterious substance called ADAM. Now, though, they are united by an ideologue preaching solidarity.
