We’re tracking a big shake-up in the future of Halo. According to Eurogamer, new reporting draws on claims from well-known insider Rebs Gaming suggesting Activision has not only been handed development of the next Halo title but is allegedly exploring a reboot of the series — potentially one that digs into Master Chief's origins. Take this with a pinch of salt, but if true it would be one of the biggest shifts for the franchise in years.
What Was Reported
Per Eurogamer, Microsoft gave development of the next Halo game to Activision, with a "new purpose-built team" created that is separate from Call of Duty teams. Rebs Gaming reportedly sketched a possible internal timeline of how discussions moved forward and made several concrete claims about what Activision originally proposed.
- Activision originally proposed two separate games: "a free to play multiplayer game and a campaign-only game", per Rebs Gaming.
- That campaign-only idea was described as a "soft reboot" — allegedly a campaign prototype that "doesn't follow Halo Infinite's story but doesn't retcon any previously established canon."
- Sources reportedly indicate Activision has since mooted making two separate games and instead is leaning toward a single package combining campaign and multiplayer, aligning more with historical Halo releases.
- Sledgehammer Games teams have allegedly "conceptualised and prototyped basic gameplay mechanics for both the proposed campaign and multiplayer projects", and pitched ideas around player movement.
- All of this prototyping reportedly took place within the Infinity Ward Engine — proprietary tech used in Call of Duty tracing back to Call of Duty 2 and rebuilt in 2019 for Modern Warfare.
The report notes technical implications: the work in the Infinity Ward Engine could mean a move away from Unreal Engine 5 (used in Campaign Evolved) and that the expensive, proprietary Slipstream engine is now "completely dead", per the sources cited by Eurogamer.
The Source & Credibility
What Rebs Gaming Claimed
Eurogamer relays claims from Rebs Gaming, described as a well-known Halo and Xbox insider. Rebs is directly quoted: "Activision originally proposed two separate games: a free to play multiplayer game and a campaign-only game." Rebs also warned: "Please keep in mind that Activision's Halo project is in early development so things can change."
We should be cautious. Eurogamer emphasises that the coverage is speculative and that the only confirmed fact, per the reporting, is that Activision will be developing the next Halo title. As such, we’re treating these claims as unverified leads — interesting and potentially huge, but not final.
What It Could Mean
If the claims are accurate, there are several concrete shifts that would follow.
- A Soft Reboot Focusing On Origins: A campaign prototype described as a soft reboot that "doesn't follow Halo Infinite's story but doesn't retcon any previously established canon" suggests a careful attempt to retell or reframe characters such as Master Chief without overwriting existing material.
- Technical Realignment: Prototyping inside the Infinity Ward Engine suggests Activision could be moving away from the technology used by the most recent release. The report explicitly links that work to path tracing and ray tracing capabilities of the modern engine rebuild.
- Team Structure: Rebs suggested the ownership team for the new title may be built "within Sledgehammer Games". That aligns with claims that Sledgehammer staff have already prototyped campaign and multiplayer ideas — a development detail we previously touched on in our coverage of Activision And Sledgehammer.
- Consolidation Rather Than Two Separate Releases: The apparent move away from splitting multiplayer and single-player into separate products to a single combined package would mirror traditional Halo structure.
