Searching for Beard

Vagabond says that Beard, his brother, has the Phobos artifact, but he's being held hostage by Monolithians at Jupiter, at some pit at an abandoned pipeline construction site.
It's highly desirable to bring the PTRD with about 35-40 rounds for this mission.
== Walkthrough ==
Travel to Jupiter and head over to the [ pipeline construction site].
28 Monolithians will wait you there; since the place is fairly open, it's probably easier to snipe them using the hills or buildings at the [ Yanov station] as a cover.
One of the shacks at the pipeline construction site has a hole in the ground inside, blocked by the concrete slab.
Upon approaching it, Marked One will message Vagabond, asking where Beard is. The slab is a physical object. You can't pick it up, but you can move it to the side by using your shotgun/machinegun, or the Gravigun.
Move the slab and enter the underground hideout by taking the ladder. Beard will spawn inside. Talk to him. He will tell you the location of his backpack with the Phobos, starting Beard's backpack. This mission is timed, don't leave.
== Notes ==
* If you want to leave the location to organize your stuff, do it before approaching the shack and triggering Marked One's message.
== Bugs ==
* Beard will only spawn if you use the ladder. The trigger is too small and you can miss it if you simply drop down.
