Injustice: Gods Among Us offers 24 playable characters (with more to come), and they all come with multiple costume variations. With so many ways to dress up your DC dolls, you'll need to know how to collect every new look. This guide will tell you exactly how to do that.
Note: Some costumes must be unlocked through external means. In other words, they are only available through pre-orders or are exclusive to DLC packs. These cannot be unlocked within the game, though they may become available for purchase later.
