Halo: The Master Chief Collection

Halo: The Master Chief Collection

Halo CE: Infantry
How do i install this mod manually?
There's a few things i wanna experiment with, mainly - switching between Master Chief and regular infantry...

how do i install the mod manually, though? I see the regular map files, which is great - just replace them... but then there's json files, campaing config files etc.

Where do these go? How do i install them manually?
