The Rumored Halo x Call of Duty Collab Gets Painful New Details

New details have come to light about Call of Duty’s rumored crossover with Halo that never materialized. TheGhostOfHope, who is a reliable source of unannounced Call of Duty information, said Sledgehammer Games was planning a “huge” collaboration with Halo for 2023’s Modern Warfare III. This would have included “various maps” from Halo coming to Call of Duty as multiplayer maps.

After Microsoft bought Activision, many began to theorize that Master Chief would inevitably come to Call of Duty as a playable character. He never has, and many are wondering why. In 2024, it was reported that the supposed collaboration was “scrapped” for “completely unknown reasons.” Social media user Alaix says they have screenshots from the collaboration but hasn’t released them.

Before this, Microsoft’s Fallout franchise crossed over into Call of Duty, so there was some precedent. Outside of this, Master Chief came to Fortnite years ago.

In other Halo news, the team working on the franchise is now known as Halo Studios. Multiple new games are in the works and they will be made using Unreal Engine 5. For more, check out everything we know about the future of the Halo series.

As for Call of Duty, Black Ops 6’s new Season 2 update arrives today, January 28, ushering in new maps, modes, guns, characters, store bundles, and more.
