A report on gaming website Kotaku has revealed that several core staff members of the development team on BioShock Infinite have quitIrrational. The report also says that the game's multiplayer modes have been completely axed and that it may now ship as a solely single-player experience. 

The list of departures iinclude design director Jeff McGann, producer Joe Faulstick, principal systems designer Ken Strickland, senior level designer Steve Gaynor, and systems designer Tynan Sylvester. Rod Fergusson, former Director of Production at Epic Games, has been brought in to help finish the game.

Irrational's Creative Director, Ken Levine, has appealed for calm and says he's confident that BioShock Infinite will stll ship in its planned release window in February in 2013. Levine also says that Jordan Thomas, designer of the Fort Frolic level in the first BioShock and the line producer on BioShock 2, has been loaned out to Irrational by its sister studio, 2K Marin. He stressed that the core development team was still in tact.

"In a company of 200 people you're going to have turnover," Levine told Kotaku.

"As far as the team itself, the lead artist, the art director, the creative director, the lead effects artist, the senior sound guy, the lead programmer and the lead AI programmer from BioShock 1 are all on BioShock Infinite."

"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," he said.
