Okay so I've seen everyone's losing pose in survival mode but the game still won't give me the achievement. Yes I have Alpha and all the other characters. (I got exercise newbie). Anyone know if there's a trick to getting this?
I believe this includes Alpha 152, Akira, Sarah, Pai, and Gen Fu. Play through story to unlock Akira, Sarah and Gen Fu, and unlock 100 titles to get Pai. Unlock all 'basic' titles to get Alpha 152 (All the ones you obtain through story mode)
