Activision Reportedly Eyeing a Halo Reboot, With Sledgehammer Games Leading the Charge
Halo·October 3, 2026

Halo's next chapter may look very different from anything fans have played before. According to a new report from well-known Halo and Xbox insider Rebs Gaming, Activision is considering a full reboot of the series, and Sledgehammer Games is said to be at the center of the effort.
The report builds on earlier news that Microsoft handed development of its next Halo game to Activision. As part of that move, a "new purpose-built team," separate from the groups that work on Call of Duty, was created to oversee the franchise going forward. Rebs Gaming now claims to have pieced together a rough timeline of how the decision unfolded inside Microsoft.
The most eye-catching detail is the creative direction. Rather than continuing the story from Halo Infinite, Activision's take is reportedly a reboot that could explore Master Chief's origins. That would mark a sharp break from the Halo Studios era, which has leaned on Unreal Engine and continued the established timeline.
Sledgehammer Games is best known for its work on Call of Duty, including Advanced Warfare, WWII and the Modern Warfare series. It would be a notable choice to lead a franchise that has long been tied to a very different style of sci-fi shooter, though the studio's experience with large-scale campaigns and shooters could make it a logical fit.
It is worth treating all of this with caution. The report comes from an insider, not from Microsoft or Activision, and neither company has confirmed a reboot, a development timeline or the involvement of specific studios. Plans at this stage can also change, and a reboot could mean different things, from a soft restart to a full reimagining.
Still, the story fits a broader pattern. Since Microsoft completed its acquisition of Activision Blizzard, the company has been reshuffling how its biggest properties are developed and by whom. Putting Halo under Activision's roof would be one of the clearest signs yet of that shift.
For fans, the big question is whether a reboot would be welcomed or resisted. Some have wanted a fresh start that returns to the series' roots, while others are invested in the long-running story of Master Chief and Cortana. Until official word arrives, expect plenty of debate and few firm answers.
