Im trying to get the
Lone Wolf Legend achievement and it states:
Complete the campaign solo on Legendary difficulty.
Which sounds simple enough (in terms of understanding the achievement requirements). When I look through the missions I have completed on legendary, the legendary symbol only appears in the co-op section and not in the solo section. I completed all missions so far ALONE and not with anybody else.
Can anyone tell me why the legendary symbol appears in the co-op symbol and not the solo symbol?
