Injustice Gods Among Us is the best super hero fighting game we have ever played. The transition to this game onto android and ios went extremely well, and even though its not quite the same as on consoles its still a great game. The only downside to this game is how many hours you will have to play to unlock certain characters. They do this on purpose so you will spend money to purchase coins to get these characters faster. This is a free app and definitely y one we recommend.
