Halo Infinite is being developed by 343 Industries with assistance from Skybox Labs, Sperasoft and Certain Affinity. It will utilize the new Slipspace Engine. The story entered planning stages in 2015 and was referred to as Halo 6 at the time. An announcement trailer was released on June 10, 2018. The developer said that all of the scenes in the Halo Infinite trailer were running in the engine. Halo Infinite will feature split-screen again, in response to the backlash of its removal in the previous game. It was also planned to have a beta prior to its release, described as an insider flight program.
Although initially implicated to be exclusive to the Xbox Series X/S, development director Frank O’Connor stated in August 2019 that Infinite was being developed for Xbox One. He said they were “building it so it plays and looks fantastic” on the platform, but would have enhancements when played on Xbox Series X/S.
