Released in 2007, BioShock was Lost Horizon under the sea, a high-concept Atlas Shrugged critique wrapped in a frenetic first-person shooter.
Its underwater city of Rapture – an art deco utopia that looked a little like Dr. Moreau’s own playground – was a virtual ecology of post-humans jazzed on genetic drugs as well as creatures in corroded diving suits protecting skinny, drug-addled children.
Enter you as the anomalous amnesiac protagonist, battling through Rapture’s multilevel ecosystem to confront the enigmatic objectivist and Rapture’s business overlord Andrew Ryan, a kind of Ayn Rand/Howard Hughes amalgam.
