Download Zero Ammo Cost (Main Story and Separate Ways)

While there are ways to unlock weapons with unlimited ammo, this mod will ensure no bullet, grenade, or chicken egg is wasted. It supplies Leon and Ada with infinite ammo for every weapon and throwable, meaning you can focus on blasting Ganado heads instead of picking up ammo. While it does offer infinite ammo, note that it won’t show the infinity symbol; your ammo count will just remain the same. That’s how you’ll know it’s working.
