Irrational Games

Background: Irrational Games was founded in 1997 in Boston by Ken Levine and other people from closed Looking Glass Studios. In 2000 they opened side studio in Canberra.

Take-Two acquired the studio on 9th January 2006. Year after the old name was dropped off and the studios incorporated into 2K Games label, renaming 2K Boston and 2K Australia (In 2007 2K Marin was also spun off by five people from 2K Boston). These names were used for Bioshock and its sequel before 2010, when Take-Two decided to return the old name back, "to respect the studio's legacy". It was announced on February 18, 2014 that the studio will be closed down.
