It isn't all that great, but it IS my first attempt. I was actually surprised I made one, and that the thing didn't blow up when a bullet tried to go through the chamber.

Obviously, use the drag-tool and drag the chain into the chaingun. I added the laser just for phun. But if you look a bit down to the right, you will notice a tower that will blow up when you shoot. Press F to fire. Careful, though, it jams alot. Just tug on the chain and that should fix it.

Please don't rate below 3! It actually took me a while to make this!
