You can unlock alternate character costumes in Mortal Kombat X by completing Klassic Towers, finding them in the Krypt or unlocking them via the Mortal Kombat X mobile game. There are a few exceptions, with some alternate costumes only being available via downloadable content (DLC), but you can get almost every alternate costume in the game with a bit of time and effort.
Many of the alternate costumes have multiple unlock methods to make this process a bit easier. Any costumes listed with multiple unlock methods, the costume can be unlocked with ANY of these methods. You do not have complete every method listed.
Note #1: We're still refining the exact unlocking methods on a few of these costumes, so if you find anything that didn't work for you please let us know in the comments below.
Note #2: For Kombat Pack 2 we have new details on how to unlock Cyber Sub-Zero.
