Irrational Games has farewelled two senior development staff from the BioShock: Infinite team.
The pair reportedly served as BioShock: Infinite's AI and combat lead designers.
There has been plenty of movement at Irrational Games recently. BioShock: Infinite art director Nate Wells went overboard for Naughty Dog; product development lead Tom Gerriston packed his things and walked; and producer Joseph Faulstick also joined Microsoft in May this year.
More cheerfully, Gears of War executive producer Rod Fergusson exited Epic to join the Boston team.
BioShock: Infinite is expected on PC, PlayStation 3 and Xbox 360 on February 26, 2013. The project has been relatively quiet since its delay out of 2012, but a new trailer is expected this week.
