So I wanted to make a thing that could be operated completely by the drag tool. This is that thing. It's quite simple to use.

1. Drag a shell into the breech. The shells on the left are solid-shot AP. All they do is hit stuff. The ones on the right with a red stripe are HE. They are timed to explode 5 seconds after being fired. When you drag a shell into the breech, the shell will be held in place automatically by that bronze wrench-shaped device.

2. Close the breech by pulling up and forward on the red handle. It will also lock into place.

3. Turn the black handle on the gear near the bottom to adjust the elevation.

4. Once you have the gun aimed, pull the lanyard backwards to fire.

5. Pull the grey handle on top down a little to unlock and open the breech.

6. Eject the shell casing by pushing the handle on the bronze wrench-shaped thing forward and dragging the shell out. Repeat from step one.

There is an enemy pillbox with some soldiers downrange. The shells can be copied and pasted so you can shoot to your heart's content. Enjoy!
