RPG Hack?

Is there an RPG Hack? Editing?
Somthing? some way to Level the skills? (Cheat engine wont work)

In single-player or multi? explain in more details please.

sure multiplayer in server like GMK RPG lets say

No that is impossible. as with all impossible things its actually possible.. But for someone who just wants to leech its infact impossible & editing multi-sided server levels would be considering impossible for you unless you know how to forge requests and or edit them via server clients
