Neogaf has complied a bunch of the alt skins for Injustice Gods Among Us. Most of the alt skins come with the game but some are exclusives (that will be sold at a later date). Gamestop has the exclusive Red Son DLC for Superman, Wonder Woman, and Solomon Grundy. Meanwhile Amazon has the blackest night zombie skins. Some of these are screen shots from the story trailer that showed a ton of alt skins.
