How to: From "Edit Schemes", unlock all weapons, ammo, and more. Choose the option "Create New Scheme" and enter a name for your scheme. Now 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'. Pick the weapon you want to edit and change the ammo value to the infinity symbol. This will give unlimited ammo for that weapon.
