Sales for Call of Duty: Black Ops 6 are up 60% on PlayStation and Steam when compared to last year's entry, Modern Warfare 3, according to Treyarch Studios developer Miles Leslie. While Black Ops 6 has been heavily praised by both fans and critics for its stellar campaign, Sledgehammer Games' previous Call of Duty title was blasted for its short and lackluster story mode, which is likely one of the reasons for its poor sales when compared to this year's entry.
