Hephaestus at full power: BioShock 2 for Mac emerges on Steam

A surge of geothermal energy has expelled something terrifying from beneath the ocean floor: BioShock 2 for Steam. Set in the ruined undersea city of Rapture ten years after its libertarian leader fell from power, BioShock 2 pits you against collectivist visionary Sofia Lamb and her cult, The Rapture Family.

Harness the immense power of Steam by purchasing BioShock 2 now along with its DLC Minerva's Den, a self-contained adventure to the core of the supercomputer that controls every system in Rapture.

You can find out more about both games at the BioShock 2 minisite, but hurry, the sea is already starting to boil...

Minerva's Den will be available on the Mac App Store as an in-app purchase through BioShock 2 in October.
