Another two staff members that were working on BioShock Infinite have left Irrational Games.
In August, BioShock Infinite’s product developer Tim Gerritsen and art director Nate Wells also left the company.
At that time, Irrational’s creative director Ken Levine pointed out that much of the team who worked on the first BioShock were still with the studio.
"In a company of 200 people you're going to have turnover," he said.
“I don't think there's a single senior BioShock team member that isn't here, which I think is amazing and a testament to their commitment to the studio. And there are a ton of amazing people who weren't on BioShock that are on BioShock Infinite."
BioShock Infinite was originally scheduled to release this year.
It is currently due out on February 26, 2013 on Windows PC, Xbox 360, and PlayStation 3.
