Irrational Games

Irrational Games was an American video game developer founded in 1997 by Ken Levine, Jonathan Chey, and Robert Fermier in Cambridge, Massachusetts. The studio built its reputation on System Shock 2 before becoming best known for the BioShock series, blending immersive environmental storytelling with first-person combat and deep philosophical themes. Take-Two Interactive shut the studio down in 2014, with Levine relaunching a much smaller team under the name Ghost Story Games.

Irrational Games' Origin Story: From Boston to Rapture

Irrational Games was founded in 1997 by three former Looking Glass Studios employees, Ken Levine, Jonathan Chey, and Robert Fermier, in Cambridge, Massachusetts. The studio's first major release was System Shock 2 in 1999, a survival horror RPG co-developed with Looking Glass Studios that built a cult following for its atmosphere and systemic design, laying the groundwork for the studio's later work on BioShock.

Irrational Games' Key Titles: A History

System Shock 2 (1999)

System Shock 2 combined RPG progression with survival horror on a derelict starship, co-developed with Looking Glass Studios. Its emphasis on emergent systems and audio log storytelling directly shaped the design approach Irrational would later use in BioShock.

Freedom Force (2002)

Freedom Force was a tactical RPG built around a roster of original superhero characters styled after Silver Age comics. It was a departure from the studio's horror roots and demonstrated Irrational's range outside the System Shock lineage.

BioShock (2007)

BioShock is Irrational's best-known work, set in the underwater city of Rapture. The game used environmental storytelling, audio diaries, and a first-person perspective to explore Ayn Rand's objectivist philosophy through the rise and fall of Rapture's founder, Andrew Ryan. Plasmids, which granted players superhuman abilities layered into combat and exploration, became one of the game's most imitated mechanics.

BioShock Infinite (2013)

BioShock Infinite moved the setting to the floating city of Columbia and shifted its thematic focus to American exceptionalism, nationalism, and historical revisionism. The Sky-Hook and Vigor systems added vertical traversal and combat options built specifically around Columbia's floating architecture, distinguishing it mechanically from the original BioShock's more grounded environments.

Irrational Games' Closure and Legacy

In February 2014, Ken Levine announced that Take-Two Interactive was closing Irrational Games, retaining a small team of about fifteen people under Levine to form a new, independent studio called Ghost Story Games. The rest of the roughly 200-person staff was laid off, with many going on to found or join other studios across the industry.

BioShock's approach to environmental storytelling and player choice influenced a generation of games that followed, including Arkane Studios' Dishonored and Prey, both of which use similar techniques for delivering narrative through the environment rather than cutscenes.
