I was just playing the OWB dlc and lo and behold upon discovering the Strange Still I decided to linger for a minute and look around. Not too long I realized I was being attacked by something. The something was an invisible nightstalker and it was not only invisible but also unable to be hit in VATS and seemingly immortal as well. I died within minutes of encountering it as I was unable to fight back. I'm going to assume this is a glitch but why in the hell would it spawn there of all places. Please get this glitch fixed.

Anyone else run into this critter in the drains underneath the X-13 research center?

Is the creature actually killable and I just died before killing it (6 times). Is it supposed to be there? Or is this like I think a glitch?

any illumination on this would be most helpful.

edit: so they are killable and I'm an idiot for not realizing I was getting attacked by more than one creature.

Yep, got killed inside that pipe on level 2
Invisible something came out of nowhere and boom.
And Vats not working here.
Did u try using the Cattle-Shocker??
I never returned to that Area.

BTW Inside X-8 at Nightstalker Cage Area, there is an Nightstalker Holotape on top of the Cages.
Then u can do a DNS splice with Nightstalker and Robot into some Agressive Robo-Brain.

I don't think it's a bug. I ran into it as well and I managed to kill it with a Proton Axe by hitting the blurry area. I assume it is there because they were testing on Nightstalkers in X-13.

I got the animal perk and they won't do anything to me.

it's killable? maybe I just had bad luck each time I tried to kill it (as it appeared out of nowhere). I'll try it again with my other higher level character and see if it is killable. Or maybe I will attempt to use melee weapons this time around. gonna go try to kill it again. will let you know if I was wrong in a bit.

Well I found out why I died so horribly. Apparently there are a total of 6-7 invisible nightstalkers wandering around in the basemant. One of them also spawns on the stairs near Dr. Callis. They also pack a bigger bite than regular nightstalkers (or so it seemed) and they seem to not spawn until you actually enter the the room with the Still; then they can appear in the tunnel, in the same room, outside of the tunnel, etc...

I was not expecting those nor that many. I was trying to kill one when six of them had ganged up on me...stupid invisible nightstalkers.

so yeah probably not a glitch...just an annoyance.

Or enter the room on level 2, back out then close door and deactivate the Blue Force Field on level 1,
then u can take em out from upstairs.

They are killable. There is a few of them. While they are invisible VATS is not suppose to work on them. Also once you trip the trigger event in the pipe system they spawn all over the facility. If you can't figure out what they are you don't deserve to know. :hehe:
