Request "Man-in-the-Middle" attack on server based games (Focus: Injustice 2)

[Aburak99 2 iPhone 6 10.2]

Name of app you want hacked: Injustice 2 Mobile

Version of the app: Latest (Current: 1.2)

iTunes URL for the app: https://itunes.apple.com/ph/app/injustice-2/id1109008423?mt=8

Requested features: Possibility of the method so-called "Man-in-the-Middle" Attack (MITM)

Jailbroken or Non-Jailbroken: Jailbroken (Hesitation surrounding Non-Jailbroken devices)
 
I have been doing researches about a method so-called "MITM". Basically, it provides you information about the so-called "packets", passing through the client (in this case: Injustice 2 servers) to the user (you) and vice-versa, continuously. These packets include information that can be adjusted to your desire such as diamonds, coins etc.
Through several sources, I have been informed that this method is mostly used by Russians that have the capability to hack games, such as Clash of Clans, Clash Royale etc.

I have tried it many times but with no avail. If anyone knows this method, I would appreciate your help.

Thank you!

Note: The person who provides this information about the "MITM" has the right to "professional secrecy" provided by me IF that individual sends the required info through private messages.

Please remember that servers often use additional API calls to ensure that any such packet editing DOES NOT result in exploits. Therefore, this will not work for most games.

Moreover, server data is often encrypted with an hashing algorithm with a private key.

Thank you, I appreciate your help. By the looks of it, Injustice 2 is a game that is non-hackable?
