Take 2 has renamed Irrational's US and Australia offices to 2K Boston and 2K Australia.

The move comes after the completion of Bioshock and symbolises the integration of the teams into the T2 operation.

"Irrational Games is widely recognized as one of the most innovative development studios in the world," said Christoph Hartmann, president of 2K. "Following their incredible efforts in bringing BioShock to life, we are proud to make the newly renamed Irrational Games studios a cornerstone of our game development family."

"We're proud to be part of the 2K Games family and enjoy the new opportunities and artistic freedoms this strengthened relationship provides," added Ken Levine, president and creative director of 2K Boston.

"The name change signifies our growing position as a central
part of 2K Games, and we plan to ensure our future titles continue to set new standards of quality and innovation for the industry."
