Ahahah I thought GF has been hacked already on this forum I hoped it :P
EDIT: I think these are the possible client modification, pls correct me if I'm wrong:
-Intro Bypass
-Attack Speed
-Mov. Speed
-Attack Range
-Buff duration
-Multiclient
-Teleport
-Wall hack
-Gravity
-Dupe items
-Zoom Hack
They are not the same for all games right?
