When Mortal Kombat 1 initially released, there were some signs that the game might have been rushed out the door just a bit sooner than it should've been.
One of them is the Mercy feature, the ability to give your opponent a bit of life instead of performing a fatality. As nice as it sounds, people usually did it to get a brutality instead, or simply to flex that even with the Mercy bonus, they are still winning this match.
Either way, the feature was cut from the final release of MK1, but it was immediately found in the files, with some players also getting challenges to perform Mercy in spite of it not being possible.
Modder known as thetiny managed to restore the feature, and as it turns out, there was even an animation for it.
