Call of Duty is the best-selling game almost every year, but even that might not be enough to keep up with its ever-ballooning blockbuster budgets. New court filings reveal that 2020's Call of Duty: Black Ops Cold War cost $700 million to make over the life of the game,

Thanks to the incredibly sharp eye of GameFile’s Stephen Totilo, he managed to dig out the Activision-stated costs of three major Call of Duty games from 2015 to 2020,

For 2019's Modern Warfare, developed by Infinity Ward, the total cost of development was reportedly $640 million with 41 million copies sold. The last one is Black Ops Cold War from 2020. Treyarch and Raven Software's joint project reportedly took $700 million to develop and sold 30 million copies.

The most expensive Call of Duty game published by Activision recoded the lowest sales according to a recent court filing.
