There's two?!?

Well in the help wanted Halloween DLC.
You can get the vanni mask and it looks like that.
Idk why my suit is very different then the mask its just the way they made it

yes, but since yours is different, was there another worker?

No it's just a creative design choice, on purpose to giver the designs more individuality amd depth like how monty has extra teath, but if you don't except that yes helpi confirms it is a thing technicians actually get, level 5 faz technician to be exact

i know, it's just a theoreme (theory meme)

prob from that one sb trailer.
