The !ammo command doesn't do anything if you use the cow mangler, so if you get to a part of the map that doesn't spam impulse 101 every 2 seconds it's literally unplayable. I know the cow mangler doesn't technically have "ammo", however if you use the !ammo command it should make it so you never have to reload the cow mangler, because otherwise it will just run out of its clip and you will have to reload mid-jump.
