So I completed a score attack mission about an hour ago and have yet to receive my achievements for them. I did the first mission with a skull multiplier of 7.5 on it so that I would complete the earn at least 10000 points achievement, the 50000 points with at least a x2 multiplier, and the 500000 points achievements but have yet to receive them.
UPDATE- Almost a day has passed and still nothing.
So apparently all score attack stuff has to be done in co-op to count for achievements. Maybe it would be better if all the achievements actually TOLD YOU THAT.
They do tell you that…

On one achievement. The others say nothing about having to be done on co-op.
So you’re saying that we only have to do that co-op and they will pop up ?
And another thing, what about the Firefight ones ? I didn’t unlocked any of that… Don’t know why
