Here is is a set for Legendary.
All the Chapters have been modded to where you should have infinite ammo for weapons and infinite grenades and molotovs (if you already have that weapon).
DO NOT RELOAD THE WEAPON WITH INFINITE AMMO or it will reset the clip so then you'll have to reload again.
IF YOU SWAP YOUR WEAPON WITH INFINITE AMMO WITH ANOTHER, THE NEW WEAPON WILL NOT HAVE THE AMMO.
