To report the news is Jeremy Penter was in particular on Twitter, based on information detected by Certain Affinity, the team that would be working on the project with code name Tatanka, or the new and big multiplayer mode planned for Halo Infinite on which the developers have been working for over two years.
Jez Corden has also returned to this issue, looking for confirmations which, however, are not there at the moment. It is true that Certain Affinity seems very close to the use of Unreal Engine, so much so that the job advertisements published are aimed at personnel experienced in this sector, but this is not enough to be sure of this information.
As Corden points out, such a change in technology would represent a major chaos for a live service game whose support is continuous, but it is also true that it could simplify the work of 343 Industries in the long term. It would also be a considerable waste, considering the time and resources invested in creating the Slipstream Engine, which should represent the technological basis for the Halo series in the future.
Considering that the codename Tatanka, that is the multiplayer mode that could have to do with battle royale features, should still be connected to the progression in Halo Infinite and with the Forge, it is difficult for the various components to be based on different engines, therefore or Certain Affinity is still working on Slipspace Engine and references to Unreal Engine have nothing to do with that project, or else all Halo Infinite has to make a technology change, but the matter seems rather dubious at the moment.
