The next Call of Duty is subtitled World at War and developed by Treyarch.
It will feature co-op for the first time in the series and is heading to PC, Xbox 360, PS3 and Wii, according to the first details - spilled from the pages of GamesTM magazine and read by VG247.
The Nintendo version will be handled by a separate developer, we're told, but all will be built on the Call of Duty 4 engine.
Call of Duty: World at War is set back in World War II amid the Pacific struggle between the US and Japan.
Content is said to be as gritty and mature as any game around. Apparently the opening shows a Japanese commander stubbing a cigarette out in the eye of a prisoner before slitting his throat and turning to dish out a similar fate to you. Is that gritty and mature enough for you? Is it?
There's no word on a date just yet, but word comes off the back of Call of Duty 4 managing to sell over 10 million copies and retake the top-spot of most-played game on Xbox Live from Grand Theft Auto IV.
Look out for our thoughts on Call of Duty: World at War in the nearish future.
