Hi all. First off, I'm a new user around here, but I'll probably introduce myself in the introduction section in more detail.
However, there's something about me that relates to what I'm about to post. I attended Evolution World Championship 2013 this past summer and competed in Mortal Kombat and Injustice: Gods Among Us. As it is known in the blind community, fighters ar for the most part, accessible to play. Injustice though, introduced a feature that gave an unfair advantage to blind players, especially like someone like me who participates in tournaments. injustice allows players to interact with objects around the arena during the match. obviously, if you're blind it's difficult to know where these interactibles ar located. Unless you're like me and decide to find a guide that describes the arenas in full detail and memorize where each interactible is located.
During Evo however, I got to speak with some of the guys of NetherRealm Studios who were very awesome and listened to my concern about interactibles. They didn't only listened to me to be nice, they actually took my concern at hand and they added interactible sound cues that allows a player to be notified when near an object in order to utilize it. Because of my attendance at Evo, I now keep direct contact with NetherRealm Studios and they were happy to add this feature to the game.
On October first, NRS has released a patch to balance characters and to fix some general issues, which also includes interactible sound cues. Obviously there are some features of the game that are still not accessible, but this is a steph in the right direction, especially since it shows that NRS really listens to the community. I hope that if any of you play Injustice, even in a casual level, that this feature will make it more enjoyable. It definitely will for me because now I have no excuses to do better in the tournament scene.

Below are the official patch notes. Most of the fixes deal with balancing the characters for the tournament scene. Nevertheless, NRs managed to include the sound cues as part of their general game system fixes. And for that, I'm forever thankful to NRS.
