You let the magnitruck move forward while the group exits and carefully goes the opposite direction. Doing so leads you to the left side of the Command Center.
You see that thee are large bay doors allowing the magnitruks to follow the lift in and out, but they are closed, and guarding the doors is a well armed security robot.
(You are now in the area marked "sleeping quarters" looking toward the right. The doors you see are the doors just above the marking "VI/C" by the number 18.)
The robot with its extrasensory perception--infrared, night vision, etc.--is alerted to your presence as you approach. There are small areas you can jump behind for cover during the fight, but a fight is now inevitable. It begins lowering the guns in its hands. They are large and look deadly.
NOTE: There are many technologies that have developed since these adventures were published. I am modifying them somewhat to avoid an antiquated feel. One thing, for example, is that they clearly would have wireless technology and your characters would know that the robots could communicate to others in the carousel without actually making any sounds or talking.
