Games Halo 5: Guardians

Not the Arena one, but the xp one. What is it?

I’m not too sure. I have seen someone who was Spartan Rank 44.

Highest is 152 which will take 50 million xp.

4

ast emblem unlock related to rank I seen is 140

I can count all the way to like 73 so I’d say its around there.
