Hey there! Made an account specifically to help out with this. Got some friends going to try it soon as well. As far as the letters, maybe this has something to do with it? From the COD wiki:

A pair of car batteries found underneath a stairwell in the centrifuge/spawn room have "" written across the front.

It won't let me C&P because the letters are in Russian, but it says SPARKY.

Ok, not sure of their function but there are the Red Phones on this map as well that can be answered, its possible this has been covered in another thread, but just throwing it out there

There is now a list of the letters from node 4 on the main post. Come on people, we're so close to cracking it.

you spell "luna" with the black letters in the air...once that was done dempsey said something about "how do we open up the portal"

Also I dont think we should rule out that the letters might not be the 4th node

But Asylum can be spelled

i think we need to focus on doing the landers in a certain order can spell something, not necessarily using all the letters

also the whistle like sound can then be heard next to the pod with 4 lights on one end in the lander room next to the stamin-up

used an anagram solver with the letters, these are some ideas

NEUTRALISM ANTISERUM HAIRSTYLE HAULMIEST HYMNARIES INHAULERS INTERLAYS LATHYRISM MENSTRUAL MISHANTER MISLEARNT MULTIYEAR RETINULAS RUMINATES SEMILUNAR TERMINALS TRAMLINES TYRAMINES UNEARTHLY UNREALITY

ill keep looking around, those are what came up

you dont need to use all the letters. you spell out the word "luna" to activate the 4th node. Couldn't figure it out after that.
