BioShock Infinite's AI lead, Don Norbury, and combat design director Clint Bundrick are now at Microsoft, Superannuation tweets. Norbury's new job at Microsoft is senior software development engineer, while Bundrick is senior designer, their LinkedIn profiles read.

Four Irrational employees left the studio in August. The most surprising departure was Nate Wells, who had been with Irrational for 13 years. Irrational Games founder Ken Levine said these employees were part of a normal turnover for a company of 200 employees, and they wanted to "spread their wings."

BioShock Infinite is set to drop in February, and the first trailer in four months is set to be revealed on October 21.
