Bigger, badder version of my first artillery, includes explosive ammo.

ETA - how long it will take for the shells to get there.
Distance - The distance away from the cannon, max is 3000 meters/1.86 miles.
Angle - Whether the angle is low or high.

Controls:
Enter - fire.
1 - Switch between low and high angle.
Arrow keys - control test car.
L - destroy spawned ammo.

Notes:
Position tracker is the red thing on the test car. It can be detached and moved by different methods (airplane, rocket, etc).

After you shoot the projectile zoom out all the way and follow it to see where it lands.

It's accuracy is within 2 meters.
