Most game files are so called server sided but are not you may not know this but they are held in a different location altogether they are hosted on the server not in the game files so its theoretical possible to hack into the server and change the values and i know this works because i have done it before on 1 game, they use complicated algorithms and you have to move backwards with the values to find your value of health etc but i don't know how to do this any more because i stumbled onto it a couple years ago and couldn't figure how i did it when i did do it.
