Ever since the idea was popularised by Fortnite, we’ve seen Call of Duty feature many different crossovers across its recent entries. Curiously, according to one insider, 2023’s Modern Warfare III was going to have a pretty substantial collab with Halo, including full-on maps and more.

As shared by known Call of Duty leaker The Ghost of Hope, “Sledgehammer Games had plans to do a huge collaboration with Halo with Modern Warfare III which would have added various maps from the Halo franchise.”

COD’s previous crossovers have been somewhat hit-or-miss, but the idea of Call of Duty and Halo collabing would have broken online forums back in the day.

Why this crossover ultimately didn’t happen was not shared, however given the relatively turbulent development of MWIII, its cancellation is perhaps not too surprising.

It’ll be interesting to see whether they have another stab at it for Black Ops 6.
