On 28 February 2011, 2K Australia's studio head, Martin Slater, abruptly left the company. On 20 October 2011, layoffs hit 2K Marin's Australian studio, with 15 jobs cut. Following the layoffs, on 28 November 2011, it was reported that the studio had dropped the 2K Marin label, and was working under their 2K Australia name again, this time on BioShock Infinite.
