I originally intended for this to release alongside Halo 4 from the MCC on PC but I'm a bit late!
Nonetheless, here it is! Master Chief as a LAS model!

I recommend using the M6G Magnum weapon mod along with Chief!

Drop into mod_overrides to install
Requirements:
SuperBLT
BeardLib
Legendary Armour Skins

There should be no issues with this mod, but if you find any, please let me know
