Thecw how's this for a planet buster, notice the huge barrel down the center? There is even a battleship docked to the left.
I thought it was a really, really, really big table salt dispenser.
This defense station must be rather worrisome for the people on the planet below. "I am here to defend you, that is why i am pointing my big gun at you. Oh yeah, before i forget it. It is rather expensive to defend all of you, so maybe you can make a generous donation to the neighbourhood defense fund."
But seriously: Not really my thing, but another nice one nevertheless.
