Could I unlock characters for Mercenaries from doing Campaign mode like playing as Helena in Leon's Campaign? Because I'm awful at Mercenaries. Or do you have to unlock them from getting a B rank or higher on specific stages?
Probably not. It seemed a lot easier to get a B rank there then it is here.
really? I feel like its easier in RE6 to get a higher rank? I've gotten an S on most new maps that my friend and I played on when were just exploring and looking for all the time-extensions... If anything, I thought RE5's mercs was harder because of the difficulties of the location of these hourglasses and how far out of the way they were sometimes. Heck bosses don't show up in RE6 unless you get X amount of specific kills/attacks.
in RE5, it felt like keeping the combo going was more difficult
