This week, Halo developer 343 began testing Halo: The Master Chief Collection Season 8 content for Halo 3 and Reach, giving players their first taste of new "alternate universe" armour skins – and it's fair to say they've sparked quite the debate within the community.
Season 8 of MCC is called Mythic and showcases Halo "in a deliberately divergent way", 343 franchise and narrative writer at 343, Jeff Easterling, said in a post on Halo Waypoint.
He's not kidding. Each of the new armour sets for use in Halo 3 multiplayer within MCC is focused on "reimagining the core Mjolnir armour as alternate universe amalgams based on legendary ancient warriors", including Greek and Norse mythology. We're playing as Spartans, after all!
