Hello and welcome to Comms-Plex 154/2f
Right before the second heal station, the heal station with the elevator in the same room. The room right before that is where the puzzle it.
Thank you Hans for guiding me through.
So theres this graffiti on the ground with the Chaos undivided symbol scrawled onto the ground and the candles around it, what you need to do it go over to the plaque that is facing towards it and scrawled on the side of it is the answer. Sorry its not the best shot of it. Light the candels with the same symbols from the plaque and the door will open, now you have the skull and the plasteel, Gratz. Bye.
