The crews approach the entry of the [thick metallic two-sided sliding door]. Surprisingly, the security system grants access for them to enter right before they even ask. The door opens with loud hissing piston noise and shows them a lift to the lower floor. They enter the lift and go down.

As they go down to the lower floors, they see pistons pump, spinning large gears, [robot limb moving noise] robotic arms, and a few drones working inside. The ear-rupturing rumble of the industrial noises could be heard through their protective bio-suit. They glance at the magnificent view of the near-floorless interior of the building which serves an unexplained purpose of this building. They'll soon find out.
