Super Dead Rising 3 Arcade Remix - Unlock every costume
Nick's Wardrobe, Annie's Wardrobe, Chuck's Wardrobe, and Frank's Wardrobe all have the requirements listed. You will be required to get all eight arcade machines, kill zombies with certain costumes, S ranks on all four districts, and complete a certain amount of districts as certain characters. The easiest and quickest district to play is Ingleton, but it's entirely up to you which one you want to play.
