As the drones traveled forward through the complex, and through the supposedly motion sensor door. It hissed with a puff of smoke as it rotated then slid apart, revealing a small chamber inside. This was no doubt a depressurization room, and once the door shut behind the drone, it cycled in a violent manner. Through the drone's feed, Silas and his crew could see the next door open in the same manner as the previous, opening up into a replica of the same hallway they just left. This room didn't contain the same dark, murky substance that permeated the past few rooms. It had many similar aspects to the previous hallway - the same odd setup, with a large open walkway in the center, and off to the side was a smaller, sectioned off hallway that was separated by pipes. As the drone traveled forward, noises in the distance were faint but noticeable. Seemingly in an instant, the drone abruptly lost its video feed, reporting back that the chassis of the drone had been destroyed.
