Microsoft’s flagship shooter may be gearing up for a surprise PS5 debut, and it’s not the Halo you’re expecting.
There are new rumors that Halo might be coming to the PlayStation 5. This is one of the strangest and most intriguing rumors in game history. But wait, this idea might not be Halo: Combat Evolved or the Master Chief Collection running natively on Sony hardware. It could be something completely different.
The report says that data miners have found links in the API to a new Halo game that works with PlayStation in every way. The listing was seen to be connected to PlayFab, Microsoft’s cross-platform service for progress, matchmaking, and unified online features. In addition, two different entries, one of which is marked as a beta, everything until now is pointing to a new game that is specifically designed for multiplayer play.
The most popular theory? This could be Certain Affinity’s long-rumored Project Ekur, which is an ideological follow-up to the Halo project codenamed Tatanka that was canceled. The game was first advertised as Halo’s take on battle royale, but it has allegedly been changed into a new multiplayer experience with its style—less “classic Halo campaign” and more “live service battleground”.
The move makes great sense from a business point of view. Live service models depend on reaching a lot of people, and releasing a game on a lot of different platforms greatly raises its chances of being a hit. Since Microsoft broke the rules by putting Gears of War: Reloaded on PS5, a Halo crossover doesn’t seem impossible anymore; it just seems strange.

From a business point of view, this could also give Halo as a brand a much-needed boost. The series used to be Xbox’s unbeatable crown jewel, but in recent years, it has lost some of its power. Putting it on a platform with more than 50 million daily users might get people interested again, and it might even win back fans who switched to PlayStation after the Xbox 360 era.
The time is right to make an announcement. It has already been said that a big reveal will happen at the Halo World Championship, which takes place from October 24th to 26th. Microsoft may drop the bombshell about Project Ekur right now. They might even start a surprise beta for the holidays.
Not like other crossovers, this one will happen. It’ll be the moment Halo stops being exclusive to one system for decades, which will mean a huge change in how Xbox handles its older games. Now the question is simple: will Halo’s release on PlayStation mark the beginning of a new age, or will it just be another test run in a business that is changing the rules all the time?
