Injustice: Gods Among Us Ultimate Edition (UP)

Win all story mode minigames

Every minigame will automatically be played during story mode, but you must WIN the game in order to unlock the achievement. Every minigame is essentially hitting the correct buttons in enough time to prevent your opponent from harming you.

IF you fail to beat the minigame during your first playthrough of the storymode, DO NOT FEAR! Below are all the minigames, where they are located, and how you can know you beat them. Simply go to Single Player - Play Story - Chapters and then load up whatever chapter you didn't beat to unlock your achievement.

Alternatively, when you encounter a minigame during the story mode, if you fail, simply exit to the main menu, then choose to resume playing your story. You will be taken back to the beginning of the minigame to try again. - Thanks to The Heape for pointing this out.

You can also pause and unpause the game as many times as you like to see what buttons you need to press. It will not affect the achievement or minigame at all. - Thanks to The AuD Doc
