Noise.
Deafening noise was all you could really hear as your entire world fell apart around you.
And all your child self could do was helplessly hide under a table as everyone you ever knew was was probably dying...Or already dead.
Eventually the screams of pain and terror stopped, and was replaced with eerie silence. So much for your home bunker being machine-proof...
It felt like forever until the door to the room you were in opened slowly, and two red robotic creatures scaling the wall crawled in at a speedy pace. One staying on the wall, while the other travelled up to move around on the ceiling, the blade on the end of It's wire-like tail scraping the wall as it did so. They seemed to be scanning the room for survivors. Eventually the one one the ceiling dropped down to the floor with a thud, and It's glowing red eyes met yours "Found one!" he alerted the other one. The other one darted over "Lemme kill the human this time, Reesy!" he said excitedly. 'Reesy' took a closer look at you "You're pretty small for a human..." he commented, quickly grabbing you and pulling you out from under the desk. "A child!?" they both asked in unison. They were never really told what to do if they ever find a kid. Reesy looked up at the other one "Bloodmoon, we can't kill a kid!" Bloodmoon looked like he wanted to disagree, but he kept his mouth shut.
Yea, they just wiped out everyone you knew, so you were pretty much screwed if they didn't bring you with them. But if they brought you with them, they would probably be blacklisted and hunted down by their creator and other machines.
