A pretty big update to the Injustice: Gods Among Us mobile version has arrived for October. They have added new character skins, which come from the hit console video game, Batman: Arkham Knight and from the hit TV series, The Flash. So you can now play as the Arkham Knight, Batman and few others from the game, plus as Barry Allen and Reverse Flash from The CW television series.
Also added is new gear and a new Survivor Mode to the game. This is all available now in the latest update for the game. So update your copy if you already have it, or download the game for free from the iTunes App Store or the Google Play Store.
