Call of Duty players will want to circle January 28 on their calendars as Treyarch confirms something big for Black Ops 6 and Warzone.

Black Ops 6 reportedly cost Activision $700 million to develop, with Black Ops 3 and Modern Warfare 2019's budgets also revealed via court documents.

In a new report from Game File, journalist Stephen Totilo has shared the budgets of Call of Duty: Black Ops 3, Modern Warfare (the 2019 one), and Black Ops Cold War, all of which have reportedly been revealed by Activision's head of creative for Call of Duty, Patrick Kelly, in a court filing.

In a rare disclosure, Activision has unveiled the staggering development costs for three of its flagship Call of Duty titles, including Black Ops Cold War.

Three Call of Duty games published between 2015 and 2020 cost almost $2 billion total in development costs, according to a court filing published in December, as first reported by Game File and reviewed by Polygon.

Call of Duty on Steam has lost all the players it gained with Black Ops 6's launch over the course of one month.
