Call of Duty: Black Ops 6 is reportedly going to have multiple collaborations with Xbox IP. According to Fumo Leaks and VondyIsPog, Black Ops 6 will have a crossover with Halo, DOOM, and Gears of War. The expectation is that Master Chief and DOOM Slayer will be joining the game as an operator. As for the Gears of War collaboration, it remains to be seen.

It was leaked in October that a collaboration between Halo & Modern Warfare III was planned earlier this year, but it was either canceled or delayed. It wouldn’t be too much of a shock if a collaboration with Halo, DOOM, and Gears of War does come at some point.

Also with larger cross-overs, they might have limited-time game modes for players to enjoy, but that part would remain to be seen.

As always with leaks like these we must take them with a grain of salt until Activision and Treyarch make it official.
