I've seen numerous generators for coins and souls, just don't know to trust them or not such as this http://mortalkombatx.ninja
It says its free and you enter your games username, I'm on the fence about it :/
I know this is an old post but would like to clarify somethings : The thing is there are no generators which can hack or give koins , souls with anti ban systems for mortal kombat nor games like injustice and so on.
1,The way to hacking android and IOS is different so one cannot use the same generator for it.
2, No one can give you anything with just the WBID. U need the password for you to access the game files saved in the cloud to edit the values.
3, It is necessary for the android device to be rooted or the IOS device to be jail broke to use a hacking tool.
I do the hacking of android MKX .. If anyone needs help let me know through PM. Just be aware of these so called generators where u mostly end up doing surveys and downloading viruses.
