The Call of Duty: Modern Warfare reboot in 2019 is seen by many to be a return to form for the franchise, utilizing a new engine for the first time in years and making some significant steps forward. The Call of Duty games released since then have earned middling reviews, with Call of Duty: Vanguard having some of the lowest review scores in the history of the popular first-person shooter franchise. This has translated to some of the lowest sales that Call of Duty has seen in years, which is apparently having an impact on the next game in the series, the rumored Call of Duty: Modern Warfare 2.
