When playing all Halo games I consistently get low scores for credits, playing with my grandchildren (they are much better than me) they have played as me but still the score I get is very low. The only difference is that I’ve played online and they haven’t. Would that cause a change to the scores? This has meant my rank doesn’t get any better, theirs has climbed rapidly so they are both senior to me, which I don’t mind.
I noticed it too. If their accounts have never accessed Xbox LIVE, they get a much larger amount of credits than someone who has played online.
Its just so players without LIVE can easily level up and unlock new armor parts.
