"At least three" revisions have been submitted to the ESRB, creative director and series co-creator Ed Boon told Kotaku, with The Joker and Kitana's fatalites tweaked.

In previous builds of the game, The Joker's fatality saw the famed villain shoot a fake gun, complete with "Bang!" flag, before pulling out a real gun and shot them in the head. Now, players will only see the fake gun bit, with the real headshot occurring offscreen.

As for Kitana, the ESRB took issue with a fatality that saw her jab razor-sharp fans through an opponent's forehead and torso. In order to be T-complaint, the head injury portion was modified, with both fans now entering an opponent's mid-section.
