Mortal Kombat X is the first Mortal Kombat game in the series to introduce character variations.
That means now every single character has three different variations.
They all share their basic attacks and combos, as well as some special moves, but they all have some unique special moves, as well as variation specific brutalities.
For example: Scorpion can now be played in either "Inferno" (Summon a deonic helper) "Ninjutsu" (Use two swords) or "Hellfire" (Adds fireballs and flame aura).
For this achievement you need to simply finish a full match wich each of the character variations.
Which means 24 characters x 3 variations each = 72 matches.
(Shinnok has to be unlocked by playing the campaing, first and Goro is not needed as he is Dlc)
I would advise you to combine this with the:
- "Win with every Character Variation"
- "Perform a Fatality with every Character"
- "Use the X-Ray" of every Character"
achievements !
The quickest way i found for now, is:
- Go to "Options" - "Gameplay" and set the rounds to 1, so you only have to win 1 instead of 2 rounds wich basicy saves you half the time.
- Go to "Singleplayer" - "Single Fight" and start with the character you want to begin.
- Win 3 matches with the character (one with every variation) and durign those, use the X-Ray of the character, perform one fatality with the character and if you want to perform one of the Brutalities of the character. (* See note)
- Rinse and repeat for every character. (Goro is not needed).
* This will help you towards the "Perform 50 Brutalities" achievement and will give you the achievement for performing 1 Brutality.
