No brainer. Updated on 10 June 2021 Former Call of Duty: Black Ops developers are making a brand new IP for PlayStation. Deviation Games was set up by CEO Dave Anthony and director Jason Blundell, both of whom worked on Call of Duty at Treyarch. Blundell, one of the chief creators of Call of Duty's popular zombies mode, left Treyarch in 2020 after 13 years. Blundell began working on nazi zombies - the co-op bonus mode in which players fought against waves of enemies - back in 2007 for 2008's Call of Duty World at War. World at War was the first game in Activision's blockbuster shooter series to feature a zombies mode, although it was only playable once the campaign was completed. It would go on to gain huge popularity within Treyarch's Black Ops games as a fully-fledged mode separate to campaign and traditional multiplayer.
