All weapons hurt hack?

Never seen a hack that all weapons hurt people. All of the weapons dont work except the shotty.

I wonder if theres a working FAMAS hack...

No, the only weapons that work using the Weapon Hack is the Winchester, Nades, and Flash Nades. All other weapons are server-sided, unless they are acquired using the Buy Hack which you must waste dinars and meet level requirements.

I see... But is it possible to make a hack with all weapons doing damage?

There is no way to make that possible. Damage is server-sided so you basicly have no hope in damage with weapons other then shotty, nades, and flash nades.
