Call of Duty: Black Ops 7 is a sequel to last year's installment – something that doesn't usually happen in the CoD release schedule, which in the past has hopped around between mini-series and development studios. In a first for CoD, the two games were developed concurrently by Treyarch and Raven Software.

A few Call of Duty campaigns have had co-op, so that change for Black Ops 7 is not entirely new. However, the vast majority of campaigns have had adjustable difficulties, but that is not going to be the case with Black Ops 7. This is an intentional feature designed to go hand-in-hand with the addition of co-op play.
