GIANT ARTILLERY V5

A giant artillery piece with a AP and HE shell, and two rocket types. Load any shell, then the propellant charge (unless you are using the rocket with no fins though you can if you want but then you have to hit the square button instead of the triangular one), close the breach with the lever on the bottom of the breech, lock it with the other lever, then press the button in the middle. You can ajust the angle of the cannon using the keypad.
