How do I use the mortar launcher?
1 of 4: The mortar launcher is pretty straightforward to use.
2 of 4: Pressing the left-right button rotates the mortar launcher, and the up-down button elevates it. The button in the center fires the mortar launcher.
3 of 4: Aiming is quite difficult, so it is going to take a few tries.
4 of 4: Remember how you positioned the mortar launcher and where the mortar actually hit each time you fire it. Fine-tune your shots this way until they hit their target.
