This year's Call of Duty game is the game in the Black Ops sub-series, Eurogamer sources say.
"Multiple sources" have confirmed to the site that Black Ops 4 is in development at Treyarch, and that it will be out later this year.
Apparently the game will dial back the sci-fi elements of Black Ops III to conform with Activision's recent mandate CoD feel more grounded – something provoked by the relatively poor reception that greeted 2016's futuristic Infinite Warfare.
The existence of Black Ops 4 was first mentioned by a Marcus Sellars, a man who claims to be an industry insider. He said that a Nintendo Switch version is in development at a studio that has worked on CoD games before. According to Sellars, the Switch version will support DLC, HD Rumble and motion controls.
The last Call of Duty game on a Nintendo console was 2013's Ghosts on Wii U.
COD 2018 is Black Ops 4 and is coming to PS4/Xbox/PC/Switch. It is set in the modern times and is boots on the ground. The Switch version will support DLC, HD Rumble and motion controls. The Switch version is also being ported by a company which is familar with COD games.— Marcus Sellars (@Marcus_Sellars) February 4, 2018
