Royal Zartillerist

This zombie is an igniter dessinged with Royal Artillery Regiment and it can be found in Westminster. While you ride the front cart with horses you will see this igniter at one of the cannons, firing the cannon and killing the horses. After firing, he gets off the cannon and starts walking to you to attack. If you will kill him before firing, the cannon will fire anyway (If you kill it while he is on the cannon, you will not be worried anymore about getting burn).
