Funny thing: "PSZ" ("ПСЗ") in Russian language is an acronym, which is stands for "Приборостроительный завод" ("Instrument producing plant" or "Instrumentation plant") which is located in region near Chelyabinsk. This plant produces equipment for nuclear powerplants, laser cutting machines, electroplating with titanium nitride for all purpouses, drilling equipment, robotics... So, PSZ plant really sound like a name of a place where nanomachine suits can be made. How did you guessed?
Well, maybe developers of the S.T.A.L.K.E.R. used this acronym because the PSZ plant works for the "Rosatom". So we can assume that the "Rosatom" ordered special hazmat suits from the PSZ to work within the Chernobyl Anomalous Zone.
Anyway. PSZ sounds like a good name for a hazmat suit. I can tell that for sure, because I'm collecting gasmasks and ordering them from the websites that provides all sorts of means of individual protection. That's why I asked, actually. PSZ-90MS sounded like the name of one of the goods from such websites (pozhim.ru/catalog/87 - for example). So, you picked a really good name, hehe.
The other thing that made me really interested is her machine gun. I see it's based on the PKM... is there a story behind this design or is this just a random Russian-looking fictional machine gun?
That's the stuff I like! Hot babes with hot firearms! But I wish Blacks, Hispanics and Asians would be shown more using guns for truly good purposes like fighting for their country's freedom or against oppressors.
