Yes! I saw it!
I was in mission in Wreckage, to recover two containers in the guts of this ship. Don't ask me what was on those, the mission order read "classified information." And don't ask me why we had to go there on night. I was told it had something to do with what we had to carry...
The squad was engaging with carriers in the downed vessel, deeper and deeper. Thanks God, we had a map projected in holo to show the path. And radar was doing most of the job, cause it was dark as hell. But there were those random scrambles. Don't know why, maybe due to the gigantic mass of steel...
Anyway, I was first in line at that moment, and believe me it was a true maze. After a long moment, we were approaching the place. Strangely, the scrambles occurred more and more often, it was intensifying too. Then, when engaging in a small corridor, I saw it.
It had a humanoid form, skinny and bonny, standing in light just in front of my mech. It has just popped out of nowhere. And then... Scrambles begun to become stronger, as I got distortion in my display. I wanted to shout, but I just couldn't. I think the thing was looking at me. And I heard that sound, in my headphone. That... I can't describe it. Something I won't forget. So scary I could wet my pants. Please, don't ask me what or how this sound was. I couldn't see anything, I was alone with that scream. And in a eye blink, all was gone.
No parasite anymore, no scrambling. No humanoid thing. I even removed my helmet, just to be sure it was not on my mech. Nowhere. But that sound... It was echoing in my head. It was freaky scary. The other guys in the team behind me have said they haven't noticed anything. They have just saw me stopping all of a sudden and shouting so loud in the intercom I nearly made them deaf. No one had their vision scrambled, nor seen that thing.
Eventually, we arrived at the place, but one container from the mission order was missing and the other one was open and empty. One teammate went out of her mech and inspected it, it was perfectly empty and there were some strange symbols drawn on the inside, she reported. We then went back on our feet, without any trouble, nor scrambles. From times to times, I was checking around to seek this humanoid thing again, but nothing. And I checked several times in my mech, too, to make sure it wasn't there neither.
Believe it or not, when I looked for the mission order, back in the base, I was unable to find it. So what ? I'm sure there are many things we don't know about this ship.
