Microsoft handed Halo development to Activision, and now a report suggests the publisher wants to start the whole series over again. Eurogamer‘s report comes from Rebs Gaming, who describes himself as a well-known Halo and Xbox insider, and it paints a picture of Activision pushing a reboot that would dig into Master Chief’s origins.
The report says Activision originally pitched two separate games: a free-to-play multiplayer title and a campaign-only game. The campaign idea was described as a “soft reboot” that would not follow Halo Infinite’s story but would not contradict any previously established canon either. Instead, Activision settled on a single package combining both elements, more in line with the series’ history.
The Sledgehammer Team
Teams at Sledgehammer Games have already conceptualised and prototyped basic gameplay mechanics for both the campaign and multiplayer projects, according to the report. They pitched ideas around player movement, and the work took place within the Infinity Ward Engine, the proprietary tech that has powered Call of Duty games since Call of Duty 2 in 2005.
The modern version of the engine was rebuilt in 2019 for Modern Warfare, and it handles path tracing and ray tracing well. That means Activision is likely moving away from Unreal Engine 5, which was used in Halo: Campaign Evolved. The report suggests Halo Studios’ expensive, proprietary Slipstream engine is now completely dead.
Inside the Timeline
Rebs Gaming’s video lays out a possible internal timeline at Microsoft. He says Activision’s proposal involved two distinct games, but the company eventually chose a combined package. The report also suggests that the overall team taking ownership of the new title may be built within Sledgehammer Games.
Rebs warned that the project is in early development and things can change. He stressed that all of this is speculative, noting that the only confirmed fact is that Activision will develop the next Halo title.
Master Chief’s Origins
The closest fans have come to a Master Chief origin story was the Paramount Halo TV show, which ran for two seasons before being cancelled. If Activision goes back in time to show the fascist roots of Master Chief’s rebellion-crushing origins, the report asks, will he also have sex in front of Cortana in the game? Probably not, ey.
The question is wry, but it points to a real tension. A reboot that digs into Chief’s past risks upsetting longtime fans who have lived with the character for decades. Whether the team chooses to explore those origins remains unconfirmed.
What the Report Says
Rebs Gaming’s report is based on information he says he has been told. He describes himself as a well-known Halo and Xbox insider, and his video is the primary source for the claims. The report is speculative throughout, with Rebs warning repeatedly that things can change as the project evolves.
The Halo franchise is a tentpole for Microsoft and Xbox. The company is still undergoing major reorganisation, with the recent Halo stewardship change resulting in major layoffs at Halo Studios, which has all but closed. Other studios in the Xbox division have also been affected.
| Event | Year | Detail |
|---|---|---|
| Call of Duty 2 engine debut | 2005 | Infinity Ward Engine introduced |
| Modern Warfare rebuild | 2019 | Infinity Ward Engine rebuilt |
| Campaign Evolved release | Recent | Strong reviews, modest sales |
| Report timeline | Unspecified | Internal Microsoft progress |
The Bottom Line
The report is a set of possibilities, not commitments. Activision has confirmed only that it will develop the next Halo title. Everything else — the reboot, the Sledgehammer lead, the Infinity Ward Engine shift — is speculation from a known industry insider.
The most interesting part of the report is the engine move. If Activision drops Unreal Engine 5 and leans on Infinity Ward’s tech, that changes the technical landscape for the series. It also kills Halo Studios’ Slipstream engine, which the report describes as expensive and proprietary.
The Master Chief origin story angle is a curiosity, but it is also a warning. A reboot that touches Chief’s past could upset longtime fans who have followed the character for years. Whether the team pursues that path remains to be seen.
For now, fans wait. The next Halo title is coming from Activision, and it may be a fresh start. The report suggests as much, but it is early days, and things can change.
