All right, since I’m always playing PUB it falls down on me to tinker around for Martyr Skulls and I kinda need help…
I intend to make it a guide if we manage to get all locations.
Corridor to the left after the stairs going up. I have no exact location, there was always someone else beating me to it (you know with me trying to be very scientific with buttons).
Shortly after med station section (the one with the minigame) where path diverges into two (going up or down) - not sure where (I know it’s large area, bear with me).
I discovered it by accident, don’t know exact location because grenade dealt with it.
Shortly before airlock, there is doorway to the right (or left if you’re in the airlock and you’re trying to return) - it’s up on the right wall when you enter the doorway, but before final chest on this path.
I found one on the mission with the big servo skull tower. It was near the start of the mission. One player stands on top of an elevator and another player stands inside a different elevator next to it and then the first person is lifted up to get a power cell to open a door with the skull behind it.
Found a few move but idk any map names so ill leave it
That infiltration mission where you upload bad recon data: after exiting the major ‘staircase’ (where the comms person will comment on how people will live anywhere), there’s a small bridge to continue, just past the medical station.
Going on it and going to the right instead of the left will lead you to a dead end. Turn right, you’ll see some climbable obstacles on the edge - climbing up these back the way you came will lead to a jumping puzzle that leads you to a Martyr Skull.
A person have to stay at the buttons. Get to the corridor from the broken wall. The doors have a symbol above them. The other player has to press the button with the same symbol to let you through. Do this for all gates, (I think one requires you to push the button next to the door as well)
Smelter Complex:
After the lift and the demon eye killing, open the door. Next to the med-station you can get on top on some boxes and the upper walkway, go back on that → and after some jumping you will be on top of the little chamber with the skull → shoot/smash the growths holding the door → open the door → profit
Relay station (Partial)
In the first open air section, just before the ramp down to the airlock (and the big arena power-cell collecting event) there is a door in an alcove with skulls hanging from 2 chains. one of the chains has a hook on the end, and requires a “skull weight” (?)
… didn’t find it yet but I assume its somewhere before that.
Chiasm Station:
After the firs med-station go down, there are a few RED valves you have to turn, look for escaping steam.
on the wall close to, and after the 2nd stair you can come down from the med-station’s tunnels.
in the deep command post looking place just next to the down ramp
continue in the farthest corridor from the command post its plainly visible as you start that way
in the middle level under the door leading to the next airlock
top level just before the airlock
turning all these should open the new door between the last valve and the door to the airlock
