Report 1:

Rapier team left this morning to raid target Epsilon. We’ve not been told much about this whole thing. Very hush hush. People are worried of course. Whenever something is secret, we know there’s something potentially very dangerous to be handling.
We’ve been at this for a while but I think this Epsilon thing is the real deal. We’ve been taking in potential SkyNET ‘super-weapons’ for the past five years and most of it is just junk grunts think looks complicated. Occasionally we get something good. We raked in a laser weapon a while back. No visible beam, makes it almost impossible to spot the thing firing it. We developed some thermal sensors which gave off a rough direction every time the thing fired. It doesn’t usually get that good though.
This place isn’t bad. There’s power, the security guys are rigging up a light system in case we get attacked.

Report 2:
Rapier didn’t bring back an actual example of this thing, but after reading the information they had, I’m pretty glad. SkyNET calls it ‘HNS’, hegemonic nano-system. It’s like a mechanical infection, it spreads like nothing you’ve ever seen. We’re still taking in data from the drive Rapier grabbed.
The report is going to have to wait. I need to get back to working on this data.

Report 3:
I don’t know if I’m excited about HNS, or scared shitless. This stuff is very worrying. There’s evidence here that even SkyNET is worried about what would happen if a full HNS infection breaks out.
Its intelligence grows as the infection spreads. It’s incredibly flexible and almost impossible to irradiate effectively. It’s got all these templates built into it, we found the files for them this morning. It’s horrific stuff. The HNS can infect corpses, or even living organisms, and construct a control system inside them. It’s a terror weapon. There’s a video file in this data of a human subject being infected. After a few days you can tell it’s taken hold. He keeps moving about, but when you catch a glimpse of his eyes… I’m pretty sure he could feel everything, but he couldn’t do a thing about it. It controls all the motor functions, but leaves the organs functioning, presumably to allow infiltration… I don’t fully understand this thing.

Report 4:
We activated some sort of tracker. Machines are coming. I don’t have long.
This HNS cannot be allowed to gain a foothold. If SkyNET uses it, it will target some sort of bunker complex. It’s incredibly invasive and it’s so small that it can remain undetected until there’s a seriously advanced infection. There could be a HNS strain here now and we wouldn’t know it until it started building units and infecting us. SkyNET left in a failsafe. The HNS can be brought down, but only by a superior artificial intelligence. SkyNET or one of its redundant backup systems probably. It means that if SkyNET uses a HNS, it will only be used for a certain amount of time before SkyNET shuts it down to stop it becoming fully self aware.
They’re coming now.
