plz help

when i use fly hack and land [i try do land as slowly and not too high of the floor] i die but when using zombie i can fall from pretty high and not die


off topic- how do i upload my sigs???

because i think zombies dont have fall damage and for humens when u use fly hack the higher you go it will tell the game your this high so when u slowly go down u will still die because to set a new level of hight you have to stop at a lower level
