Worms: Open Warfare Unlockable: Unlimited Ammo

Head to "Edit Schemes" to unlock all weapons, ammo, and more. Choose the option "Create New Scheme" and enter a name for your scheme. There, you can change the number of rounds, turn time, round time and retreat time, and you can edit the weapons sets by choosing 'Edit Weapon Set.' Choose the weapon you want to edit and change the ammo value to the infinity symbol. This will give unlimited ammo for that weapon.
