Med hele otte DLC-karakterer, så var Mortal Kombat det Netherrealm-spil der modtog flest udvidelser. Det lader nu til, at det kommende Injustice 2 vil følge en lignende strategi. Via et nyt interview siger instruktør Ed Boon:
"One of the things we've been doing, trying to do more and more with every game... is to support it for a longer period of time. With DLC characters, we've had four with [2011's] Mortal Kombat, six with Injustice, eight with Mortal Kombat X, and with Injustice 2 we plan on continuing that pattern."
Han forklarede endnu en gang, ved at sige at Neatherrealm "will certainly be more aggressive than we've been in the past."
