If you ever want to play a non-playable character in Mortal Kombat X, you can do it now, like “Rain” you can play with it. YES! In the guide given below you will how.
A Reddit user XVermillion, just manage to play with a non-playable character, which you can in the video below and you what it is pretty awesome and easy to do. You just need to tweak some a couple of filenames. (But first back up your game.)
What he’s done is “I backed up the files for Shinnok (the character I’m replacing) and renamed Rain’s files to match those associated with Shinnok’s first costume slot (CHAR_Shinnok_A.xxx and one other, the one that matches Rain’s other one) and moved ’em to the folder and overwrote Shinnok’s old files with the newly renamed Rain files.”
