Call of Duty 2021 rumored to return to a World War 2 setting, to be developed by Sledgehammer Games
Black Ops Cold War was the most recent title under the popular Call of Duty (CoD) franchise. While the Black Ops series is developed by Treyarch in collaboration with Raven Software, it has been sometime since we've seen Activision release a CoD title developed by Sledgehammer Games. If rumors are true, we may indeed get to see a CoD title from Sledgehammer Games this year.
This info comes via known Call of Duty leaker @Victor___Z on Twitter. @Victor___Z tweeted a poster of the 2017 Call of Duty: WWII game indicating that the upcoming CoD installment this year will also be a based in a World War 2 setting. Sledgehammer Games developed the WWII title and is said to be working on the 2021 version as well as indicated by the hammer icon in the tweet. The leaker seems to be quite confident that this will not be a futuristic WW3 title.
If the above information is true, it looks like we are in for another installment of boots-on-the-ground traditional CoD gameplay. Unlike the Modern Warfare series, WWII's campaign emphasized on teamwork for things like rejuvenating health and ammo, spotting enemies, etc. WWII's multiplayer offered players a choice between Allies and Axis sides along with the choice of selecting Divisions such as Infantry, Cavalry, etc.
Whether Sledgehammer Games would opt for similar mechanics as the 2017 title remains to be seen. That being said, the new installment may stand to benefit from modern features such as ray traced shadows/lighting, DLSS and hopefully, a longer and a more historically-accurate campaign mode.
All said and done, Activision itself hasn't announced anything officially except that a new CoD game will be coming in Q4 this year. So, it is always good to exercise some healthy skepticism until we hear things straight from the horse's mouth. The publisher's Warzone battle royale mode will continue to be featured with a possible integration of weapons across WWII and Warzone modes.
