Massively ballooning game development budgets are among the biggest issues facing the games industry right now, and we continue to see increasing examples of that by the day. Unsurprisingly, it has emerged that Call of Duty as one of the biggest gaming properties on the planet has some of the largest and most eye-watering budgets in the industry.Caught and reported by Game File, development budget figures for threeCall of Duty titles wererevealed by Activisions Patrick Kelly who is head of creative on theCall of Dutyfranchise in official court filings in December. As per the filing, 2020sCall of Duty: Black Ops Cold Warhad a development budget of over $700 million, 2019sCall of Duty: Modern Warfarereboot stands at over $640 million, while 2015sCall of Duty: Black Ops 3stands at over $450 million.Kelly states in the filing that those figures cover development costs over the games lifecycle for each game, suggesting that costs associated with developing each games post-launch content is also included.That said, its also worth noting that these figures only cover development costs- marketing costs, which usually tend to be just as high as development costs for AAA titles (especially for something likeCall of Duty), are bound to take the total budget figures radically higher for the three aforementioned titles. Then again, all three titles have also sold exceedingly well, based on figures revealed by Kelly in the filing.This putsCall of Dutyat the top of the list of highest game development budgets, though its worth noting that information on that front is scarce at best, thanks to the consistent reluctance of developers and publishers to disclose relevant numbers. Notable examples in recent years have been limited to the likes ofThe Last of Us Part 2, Horizon Forbidden West, Marvels Spider-Man 2, Concord, The Callisto Protocol, and others, though these newly revealed figures forCall of Dutyput the shooter series far above any of the aforementioned titles.
