in order to get this achievement, do i have to beat the co-op campaign as well? i beat single player, unlocked all decks (non-DLC) and all cards for all decks (again non-DLC) and beat all challenges. i am only at 81%. the achievement only says "Unlock 100%" not "Beat 100%". just wondering if i've missed something or if i do indeed have to beat the co-op campaign as well in order to get this achievement.
thanks for your help
