John McClane versus the Death Star....
John McClane is in Obi Wan's place. He is on the Death Star, barefoot, armed with a Stormtrooper E-11 blaster rifle, and a DL-44 blaster. He has also has a bag full of thermal detonators. McClane also has a Stormtrooper standard issue comlink so that he may listen in on the Stormtroopers. And of course he may talk to Han and Luke on it.
He has arrived with the Falcon, with Han, Luke, and the droids. He must find and disable the tractor beam generator, then fight his way back to the Falcon, so that he and the others can escape. Luke and Han are busy rescuing the Princess, McClane is on his own. He is free to use any and all tactics he used in Die Hard.
The Imperials are no aware of McClane's presence. Vader is on vacation, and the station is only half staffed.
Does he clear? For arguments sake, McClane is just as good with the blasters as he is with the guns he used in Die Hard.
