Deceased Section

The stairs looked like stairs that led to a dead end– an open dead-end– open for you to jump down the cliff and into the Liquid of Doom– a pool of Hydrofluoric acid– to burn, wait, no; to melt your body to nothing. 

The stairs are nothing more than escalators. When Kyoryu stepped on the first stair and lifted his foot to charge forward, the stairs started escalating him to the top. He stumbled on the next stair and danced around till he grabbed the railing. 

Hitori grabbed a face mask from the basket stuck by the escalator, then jumped on the escalator. The others grabbed masks from the basket and followed Hitori. 

When they reached the first-floor hallway, Hitori saw a few robots rolling toward them, so he increased his pace and jumped on the second set of stairs which started rolling. He turned and glanced down at the robot, it stopped near a door, then entered the room.
