me and my mate just did that challenge on legendary with 10 skulls on new Alexandria we got the 300000 points (round about) then we finished the mission and no challenge i have saved the video in theatre it is so annoying!!!
Did you get 250,000 each? Because I think you need to score at least 250,000 individually. I did it on the Pillar of Autumn, solo, getting to the MAC gun early. As soon as I got 250,000 the challenge popped up.
Yup, it’s not a cumulative score of 250k, it’s an individual score.
