"Irrational Games has consistently produced creative and original games in every genre they tackle," said Christoph Hartmann, Managing Director at 2K Games. "With 2K Games behind them, we're confident they will create some of the most innovative and groundbreaking titles for the next generation, led by the mind-blowing Bioshock."

"We saw a rare opportunity with Irrational Games," said Susan Lewis, VP of Business Development at 2K Games. "With titles like System Shock 2 and SWAT 4, they proved themselves to be among the best PC developers in the industry. 2K Games will provide additional resources and support to the Irrational team so they may extend their experience to deliver world class games for both PC and next-generation console systems."
