A rooted android device can run game memory modifiers to change in-game data.
One method is to request the android rooted right and try to kill the game modifiers which are known by name. Can Unity implement this or do you have any other advice on it?
You have to write a plugin for that. I doubt Unity will implement features that are meant for killing other processes, it is not cool (and it might be against the rules of Google Play and similar).
