[Mac Sirloin]

The lamp didn't light much. Just enough not for me to trip over protruding metal in the rotten ground.
I caught up with the Trooper. He nodded at me and we continued on.
"Where's Grace?" I stupidly asked.
"She must've ran ahead of us, man. I keep seeing her light every now and then but all I got is footsteps now." He answered.
We jogged on, following the sets of footsteps absentmindedly. Eventually we came to a close collection of junk that the steps wound around sporadically. I drifted behind the Trooper as the passages narrowed. We turned a final corner and crept into a dully lit area the size of a football field. Grace was ahead of us, apparently speaking with the Robot.
It just wandered away to work. This must be the fuel depot. I thought.
I looked around the place as best I could. There were remnants of some sort of wall around the sides, with plates of sheet metal planted to hold it together.
On top, there were a collection of dull, curved rods. I stared at one, trying to discern what it was when it started to glow.
"What is this?" The Trooper said. The Lights flashed, and for a moment we were blind. A shadow was cast over us as someone stepped in front of one. I couldn't tell who it was.
"SAUNTER!?" I heard Grace shout. "SAUNTER, IS THAT YOU!?"
The figure stepped back as an amplified sound played over an unseen speaker. It was a Tone, the kind that the 'bots used. It actually sounded old. Like someone had trapped a yell in a bubble and popped it. There was a grating sound along with it, something separate but still amplified. I heard machinery chugging nearby. Grace looked terrified, the Waste robot sat stock still.
"That's an activation tone." The trooper said. "It switches all machinery in an area from On to Off or otherwise." He sounded like he was quoting something. The sound cut, but the machinery still chugged.
The Trooper moved forward to get Grace. As if on cue, a large set of pistons shot out of the wall, instantly crushing The Waste Robot. Grace screamed and jumped back as a second set rushed forward, catching her right arm and pulverizing it. She screamed louder, immediately silenced by the third pistons. They connected with a low gong. I could still hear Grace screaming, muted.
As the second and third pistons came apart, a grate slid out of the wall in front of us.
The third was hollow, that much I could tell, as Grace fell out of it.
"Oh, god. Oh...." The Trooper vomited.
Her legs had been cleanly cut off, along with her right arm. She was still screaming. The lights above us faded and all that we could see was her Lamp, barely illuminating her prone, mutilated body. She stopped screaming, Unconscious. I heard the Trooper starting to move away. I turned my head backwards just as her body was pulled into the darkness. Something lifted her lamp high and turned it off.
I ran.
