Brian Jarrad a.k.a. Ske7ch from 343 gave us an update on Halo Infinite’s MP matchmaking playlist and challenges situation. Free-for-all, Tactical Slayer (previously known as SWAT), Fiesta, and Slayer will be added in to the game after a services update on Tuesday, December 14th.
They will also be further adjusting the challenges to remove “frustrating mode-specific ones, reducing some requirements for others, making the weekly ultimate challenge less intensive (getting there is tough enough), and adding brand new challenges specific to the new playlists.”
