Keyboard/Mouse Supported Yet?

I used to play Halo 5 all the time, but moved over to Destiny 2 when it released on PC, and because of the shift I’ve lost all hints of skill with a controller, but I can hold my own with a keyboard and mouse.

I obviously don’t want to get banned, so I was wondering if the support for it has happened yet, or if it will at all even, so I can legitimately use what I’m “good” with.

No, K&M is not currently officially supported in Halo 5. I doubt it will be.
