Microsoft has abandoned its U.S. trademark application for Halo: The Endless, ending a filing that had been active since December 2021 and survived a lengthy opposition process. The application was formally abandoned on April 1, 2026, according to U.S. Patent and Trademark Office records highlighted this week by Halo creator Sean Dubs and reported by Windows Central.
The name had long been linked by fans to Halo Infinite. The Endless were introduced in that game as an ancient species positioned for a larger role in its story, and “Halo: The Endless” looked plausible as a title for campaign DLC or a follow-up. Neither arrived. A trademark filing is not proof that a product reached active development, but abandoning it after years of legal work suggests Microsoft no longer intends to use that name in the United States.

There is no indication from Microsoft or Halo Studios that Halo: The Endless was a finished game, expansion, or announced roadmap item. The registration remains protected in at least some other jurisdictions, including Canada, so this is not necessarily a worldwide surrender of the name.
Still, the timing has drawn attention. The U.S. abandonment came shortly before reports that Halo Studios cancelled an unannounced multiplayer project, reportedly codenamed Project Ekur. The Ekur report originated with creator Rebs Gaming and was later supported by Windows Central and other outlets, but Microsoft has not publicly confirmed the project or its cancellation.
The two developments should not be treated as causally linked. One is a public legal filing; the other is an unconfirmed report about an internal project. Together, though, they underline how little is publicly known about Halo Studios’ longer-term plans beyond its next release.

Hintze on Halo 5’s narrative backlash​

Separately, Halo Studios head Pierre Hintze discussed Halo 5: Guardians in a March interview with the STEM Educational Institute. Hintze said the team’s narrative choice to make Master Chief something other than the main protagonist brought an “imminent” backlash, and that Halo Studios has expectations it must meet for players.
That is a notably direct acknowledgement of the response to Halo 5, whose marketing heavily featured Master Chief while much of the campaign followed Spartan Jameson Locke. The issue was not simply that the series featured another lead—earlier Halo games successfully shifted focus—but the mismatch between the campaign structure and what players had been sold.
Hintze also spoke broadly about games moving toward deeper cooperative and competitive experiences, citing MMO-style raids as an example of rewarding shared objectives. As Windows Central noted, he was answering a general question about games rather than announcing an MMO Halo project. That distinction matters: the remarks are not evidence of an impending genre pivot.
For now, the only concrete next step is Halo Studios’ Halo: Campaign Evolved, scheduled to launch July 28, 2026 for Windows, Xbox Series X|S, and PlayStation 5.
