I Need Help Hacking this Game

So have you ever heard of Endless Online? I know I have! AND IT SUCKS! There is this game that was created from EO's engine and isometric drawing, etc. called Fallen Evoultion. It's a 2D mmmorpg. It started off as a private server but then became huge. They made their own client. As of now, they do not have any hacking protection. It's like Endless Online. If you use cheat engine on it and try to duplicate gold, it will be just client sided. I want it to be server sided. Same with duplicating items. If you can, would someone make a 1 hit kill hack? If you need any more information, please post or PM me. Thanks =D
