Jason Blundell has left Deviation Games, a studio founded by former Treyarch developers. The team will continue to work on a new AAA IP in partnership with PlayStation.

Deviation Games made the announcement on Twitter. “We appreciate the contributions Jason has made and we wish him the best in his future endeavors,” the message reads.

The studio’s co-founder and CEO Dave Anthony will continue to lead the team, also taking on the role of game director. On top of that, Westwood Studios co-founder Louis Castle joined Deviation Games as senior vice president of development.

Other team members include former God of War and Call of Duty: Black Ops developers. Together, they will be working on what they describe as the “groundbreaking AAA original IP.”

Last year, Sony Interactive Entertainment announced a partnership with Deviation Games to develop a new IP for the PlayStation platform. “We’re setting out to make a huge, content-rich game with a focus on a lot of action and a lot of energy, but let’s leave it at that for now and hopefully it won’t be long before we can share more,” Anthony said at the time.

Jason Blundell is an industry veteran who spent over a decade working on different Call of Duty games at Treyarch Studios. He went from producing Call of Duty 3 to becoming a game director for Black Ops III and the co-studio head, eventually. It is unclear what Blundell plans to do after his departure from Deviation Games.
