Rumors regarding the upcoming addition to the popular shooter franchise Call of Duty have been circulating for months. But now, multiple trusted sources have confirmed one crucial piece of information: the game's title will be Call of Duty Black Ops: Cold War.

If this information, which was first spread on Twitter before being backed up by Eurogamer, is accurate, then the new game will be the fifth entry in the extremely popular Black Ops sub-series. After 2018's Call of Duty Black Ops 4 (sometimes stylized as Black Ops IIII) took players to the year 2043 to defend the future from a zombie infestation, it looks like Cold War will be once again returning to the series' roots in the past.

The rumored title raises as many questions as it answers. A Cold War setting gives the developers quite a lot to work with, as historians generally consider the period to have lasted from 1947 until 1991. It is also unknown whether the title will feature specific events from the Cold War period or focus on original material unique to the Black Ops storyline.

Because the game will be part of the Black Ops sub-series, the development will likely be handled by Treyarch, the studio responsible for the previous Black Ops titles. Rumors also indicate that studios Sledgehammer and Raven may have also served in a support role during the project's creation.

Hints appearing throughout the free to play battle royale game Call of Duty: Warzone also seem to indicate a Cold War setting for the upcoming title. Previously silent phones scattered throughout various maps have begun ringing, with only short, mysterious messages in Russian on the other end. Also, data miners have discovered that one of the game's locked bunkers seems to contain either the schematics for a Cold War-era plane or the actual plane itself.

So far, no official confirmation has been made regarding these rumors. Publisher Activision has so far refused to comment. However, with the game still planned for a 2020 release, we will likely receive more information soon.
