There were eleven messily dead humans in the hub, sprawled on the floor, in chairs, the monitoring stations and projection surfaces behind them showing impact damage from projectile and energy weapon fire. I tapped the feed and asked Mensah to fall back to the hopper. She acknowledged me and I got confirmation from my outside drones that the humans were retreating.
I went out the opposite door to a corridor that led toward the mess hall, Medical, and cabins. The drones were telling me the layout was very similar to our habitat, except for the occasional dead person sprawled in the corridors. The weapon that had taken out the dead SecUnit wasn’t in the hub, and it had died with its back to the door. The DeltFall humans had had some warning, enough to start getting up and heading for the other exits, but something else had come in from this direction and trapped them. I thought that SecUnit had been killed trying to protect the hub.
Which meant I was looking for the other two SecUnits.
Maybe these clients had been terrible and abusive, maybe they had deserved it. I didn’t care. Nobody was touching my humans. To make sure of that I had to kill these two rogue Units. I could have pulled out at this point, sabotaged the hoppers, and got my humans out of there, leaving the rogue Units stuck on the other side of an ocean; that would have been the smart thing to do.
But I wanted to kill them.
One of my drones found two humans dead in the mess, no warning. They had been taking food pacs out of the heating cubby, getting the tables ready for a meal.
While I moved through the corridors and rooms, I was doing an image search against the hopper’s equipment database. The dead unit had probably been killed by a mineral survey tool, like a pressure or sonic drill. We had one on the hopper, part of the standard equipment. You would have to get close to use it with enough force to pierce armor, maybe a little more than a meter.
Because you can’t walk up to another murderbot with an armor-piercing projectile or energy weapon inside the habitat and not be looked at with suspicion. You can walk up to a fellow murderbot with a tool that a human might have asked you to get.
By the time I reached the other side of the structure, the drones had cleared the first habitat. I stood in the hatchway at the top of the narrow corridor that led into the second. A human lay at the opposite end, half in and half out of the open hatch. To get into the next habitat, I’d have to step over her to push the door all the way open. I could tell already that something was wrong about the body position. I used the magnification on the field camera to get a closer view of the skin on the outstretched arm. The lividity was wrong; she had been shot in the chest or face and lay on her back for some time, then had been moved here recently. Probably as soon as they picked up our hopper on the way here.
On the feed I told Mensah what I needed her to do. She didn’t ask questions. She’d been watching my field camera, and she knew by now what we were dealing with. She tapped back to acknowledge me, then said aloud on the comm, “SecUnit, I want you to hold your position until I get there.”
I said, “Yes, Dr. Mensah,” and eased back out of the hatch. I moved fast, back to the security ready room.
It was nice having a human smart enough to work with like this.
Our model of habitat didn’t have it but on these bigger ones there’s a roof access and my outside drones had a good view of it.
I climbed the ladder up to the roof hatch and popped it. The armor’s boots have magnetized climbing clamps, and I used them to cross over the curving roofs to the third habitat and then around to the second, coming up on them from behind. Even these two rogues wouldn’t be dumb enough to ignore the creaks if I took the quick route and walked over to their position.
(They were not the sharpest murderbots, having cleaned the floor of the between-habitat corridor to cover the prints they had left when staging that body. It would have fooled somebody who hadn’t noticed all the other floors were covered with tracked-in dust.)
I opened the roof access for the second habitat and sent my drones ahead down into the Security ready room. Once they checked the unit cubicles and made sure nobody was home, I dropped down the ladder. A lot of their equipment was still there, including their drones. There was a nice box of new ones, but they were useless without the DeltFall HubSystem. Either it was really dead or doing a good imitation of it. I still kept part of my attention on it; if it came up suddenly and reactivated the security cameras, the rules of the game would change abruptly.
Keeping my drones with me, I took the inner corridor and moved silently past Medical’s blasted hatch. Three bodies were piled inside where the humans had tried to secure it and been trapped when their own SecUnits blew it open to slaughter them.
When I was close to the corridor with the hatch where both units were waiting for me and Dr. Mensah to come wandering in, I sent the drones around for a careful look. Oh yeah, there they were.
With no weapons on my drones, the only way to do this was to move fast. So I threw myself around the last corner, hit the opposite wall, crossed back and kept going, firing at their positions.
I hit the first one with three explosive bolts in the back and one in the faceplate as it turned toward me. It dropped. The other one I nicked in the arm, taking out the joint, and it made the mistake of switching its main weapon to its other hand, which gave me a couple of seconds. I switched to rapid fire to keep it off balance, then back to the explosive bolt. That dropped it.
I hit the floor, needing a minute to recover.
I had taken at least a dozen hits from both of their energy weapons while I was taking out the first one, but the explosive bolts had missed me, going past to tear up the corridor. Even with the armor, bits of me were going numb, but I had only taken three projectiles to the right shoulder, four to the left hip. This is how we fight: throw ourselves at each other and see whose parts give out first.
Neither unit was dead. But they were incapable of reaching their cubicles in the ready room, and I sure as hell wasn’t going to give them a hand.
Three of my drones were down, too; they had gone into combat mode and slammed in ahead of me to draw fire. One had gotten hit by a stray energy burst and was wandering around in the corridor behind me. I checked my two perimeter drones by habit, and opened my comm to Dr. Mensah to tell her I still needed to clear the rest of the habitat and do the formal check for survivors.
The drone behind me went out with a fizzle that I heard and saw on the feed. I think I realized immediately what that meant but there may have been a half second or so of delay. But I was on my feet when something hit me so hard I was suddenly on my back on the floor, systems failing.
