The Red Son DLC which was a pre-order bonus for Injustice: Gods Among Us will be released as a purchasable pack through PSN and XBLA next week, according to the game’s Twitter account. The skins were also part of the special edition of the game released in the UK. No word on whether the skins will also come with the 20 bonus challenge missions or not, and a price wasn’t announced either. Check back for updates as more information becomes available. Thanks, Joystiq.
