The station is under siege by rebel forces...
A fleet of starfighters has entered the atmosphere and is bombing the Imperial armada. All hope seemed lost but Vader single-handedly  restored it with his presence.

A stormtrooper who was cleaning the roof half an hour ago is now falling off it. He made an impossible shot and killed a rebel pilot shooting a blaster shot through his cockpit window. The same starfighter 's fall made him loose balance and fall to his ironic death.

Another rebel platoon is advancing in the forests near the station. Shooting stormtroopers like it's no big deal. They have arrived via an old cargo transport the rebels have successfully passed the station scanners with.

Another stormtrooper in charge of calling the fleet after the communication dishes have been destroyed has given into his rage after a series of unsuccessful attempts at getting the signal through rebel blockers. After he hits it with a shovel a light goes green and he can hear distressed officer voices. Perhaps it is not over yet.

And finally Vader himself makes his appearance... These poor delusional rebel fanatics won't even know what's hit them before it is too late...
