TL:DR - Purchasing a Mortal Kombat 11 Ultimate Add-On Bundle key for PS5 and activating it may unlock the Eternal Klash skin pack, even if you already own the game.Mortal Kombat 11 Free Key by Mortal Kombat 11 Key Generator

This bugged me for a long time as I really wanted the skin pack, and it looks like it won't be in the in-game shop ever again, so I figured I'd share this solution that MAY work for you, but it definitely worked for me.

Out of curiosity, I tried purchasing the Ultimate Add-On Bundle online as a key, taking a bit of risk thinking that I may have wasted my money and gaining nothing, but alas, when I activated the code for the Ultimate Add-On Bundle, I also found myself to be the owner of the Eternal Klash skin as well! I was curious about the Physical Tracking Entitlement thing, and checked my DLCs on PS5, seeing that I don't own the Ultimate Add-On Bundle, although I have pretty much everything sans the Eternal Klash skin. To our surprise, the Eternal Klash skin bundle was also unlocked, although apparently, it is a pre-order exclusive, and we both bought the game WAY after that period.Īs for myself, I bought the MK11 Ultimate + Injustice 2 Legendary bundle in a sale a while ago and didn't have the Eternal Klash skin. Once she tried to activate it, the PS5 menu interface identified it as 'PS5 Physical Tracking Entitlement' or something similar and allowed her to redeem the Mortal Kombat 11 Ultimate Add-On Bundle on PS5 for free.

My girlfriend bought Mortal Kombat 11 Ultimate physical PS4 version a couple of weeks ago, which also comes with the PS5 upgrade code inside. Firstly, I'm emphasizing POTENTIALLY, as this worked for me but I'm not sure if it will work for you.
