Thermodynamic expansion and sheer kinetic energy alone would obliterate the shields. And it fires every 2-3 seconds lol (Super MAC odp) But that's not what I'll base the destruction of your shitty little Death Star off of. It's the sentinels... 1000 sentinels far exceed the destructive capability of the Death Star. Keep in mind that there are trillions of them and when they Conjoin their Firepower and forunner shields amplify [b]exponentially[/b]. Death Star would be a molten slag heap. None of the point defense systems or the actual primary weapon would breach their extremely overpowered shields.
