Series 7: Elite

Season 7: Elite is a planned upcoming season for Halo: The Master Chief Collection, anticipated to release some time in 2021. As of December 2020, plans had been laid internally at 343 Industries for this season. This season will notably include long-awaited additions to Elite-focused armor customisation in Halo 3, in the form of seven new harnesses, alongside the four Champions Bundle armors from Halo 4. It is possible that this season will feature OPERATOR-class Mjolnir and other Halo Online armor sets, which have been seen in the trailer for Season 5 but not yet featured as an unlock in Season 5 or Season 6.

In addition to the new customization content, Season 7 will also introduce changes to the classic Halo: Combat Evolved graphics to better reflect the original Xbox version of the game, rather than the 2003 PC port which introduced many graphical issues. Furthermore, the season will also feature improvements to the Halo Online maps Waterfall and Edge, which have been added to Halo 3, and general bug fixes.

MCC's Custom Games Browser, which had previously been briefly tested publicly on retail will launch this season, with support for Halo: Reach. Players will now be able to host their own matches available to the public. Other games are planned to be brought to the Custom Games Browser at a later date.
