Does anyone know the bare minimum gamerscore requirement needed for level 100 Career Milestone?
Probably all of the Halo achievements.

Not true. Last time I checked I was a 100 but I was missing 2 (I do not have any on SA on W8 phone, but it might not count those). It could be a glitch, or at the very least you need to get most of the achievements.
