There were many media reports and leaks indicating that the Certain Affinity development team was working on the arena combat mode for Halo Infinite, which was called “Tatanka” during the development stage.
According to journalist Parris Lilly, work on this phase has been cancelled. He is not sure whether the project will turn into a special, independent project away from the Halo Infinite game, or whether it will be transferred to the project for the next part.
