[Dez can correct me if I am wrong.]
When the guards see that the medical droid is indeed coming, they leave their wounded comrades and run back toward the battle where they are needed, Dez has to RUN to catch up to Zero, but stops beside him as he examines one of the fallen men [Still alive but at 0 on condition track, and very wounded (2 hp remaining)]
Looking into the room beyond Zero sees that there are 10 guardsmen hunkered down behind the control consoles in the main control room. Two of the guardsmen wait at the top of a set of stairs that lead down from the control room, probably to access the docking area beyond. The control room windows have been blasted to mere shards by the hail of blaster fire coming from the docking area beyond. The control room is raised, perhaps 30 feet above the florr of the docking area beyond.
In the docking area beyond is a raised docking pad, perhaps 10 feet above the docking facility floor, surrounded by a low blast wall (designed to keep exhaust and debris from thrusters from burning everything in the docking area when a ship lands or takes off). The blast wall is currently providing cover for the source of all teh blaster fire, three security droids and afew storm troopers, with one of the droids manning a repeating blaster cannon. beyond the Imperial defenders, also wiyth its docking gun providing covering fire, is an Imperial Lambda class shuttle.
The shuttle is obviously fully powered up and ready to go, but is prevented from departing y the bubble of a force field overhead.
There seems to be a stalemate. The Imperials can't take off unless they can take the control room and disable the force field, and the guards want the ship, or at least to stop all hope of the Imperials escaping to get a signal out to warn of the Mayor's betrayal of Kratos.
With her use of the Force, Shunna knows there are two Imperial stormtroopers with total cover (so Zero and Dez cannot see them because of the angle), that have made it to the door at the base of the stairs, so at an angle that the guards cannot see them either (directly below the windows, 30' down). She also knows there are a few people inside the shuttle, in teh shuttle cockpit.
At this angle only those people in the shuttle cockpit have a high enough vantage point to be able to see Zero and Dez at the back of the control room.
Time for initiatives..
