Hello, with this cleo file you can control your hitman level of different weapon types !
All you have to do, is to copy the cleo script to "[... ]Rockstar Games/San Andreas/CLEO" folder and try following combinations in-game :
H + numpad7 => Hitman level on all walk weapons (Silenced pistol, Desert Eagle, Shotgun, Spas-12, M4/Ak-47)
H + numpad8 => Hitman level on all run weapons (colt45, tec9/uzi, sawn-off shotgun)
H + numpad9 => Hitman level on All weapons.
Have fun ;D
In some SA-MP servers you start from 0 level of weapon skills, and they make you improve that weapon skill only if you kill others.
With this cleo mod, you will get full skill at any weapons and you will be able to shoot while moving in that server.
