Like the title say how to get black phantom skin in gear 5 I have one on the serre but I don’t know how do I get it
This was a reward for a GOW4 challenge a while back - it was part of the Gilded RAAM challenge which ran from March to June  I think and the rewards carried over to GOW5. If you haven’t got it, then the deadline has passed.
You are correct.
Ok thanks for the reply
