Ok this one blew me away, its another little no parkour required area and this time with multiple fairly obvious yet inconspicuous entrances, beyond being pretty this one has some pretty strong cut-gig vibes.
One entrance hidden behind a Trauma team AV, I later found prettier entrances but I'm not booting up the game with all my mods again. Its pretty winding down there but you can find a small un-marked scav event as article of evidence #1.
Star of the show is this pit, equidistant from pretty much all entrances and with a clearly deliberate parkour path all the way down.
Its a looooong way down, there's also a dead guy with a lore shard down here and a weird red fan that I all the garbage slopes into like it was meant to be some kind of entrance.
This elevator has no useable floors but otherwise appears to be completely functional, even the doors work.
Map location of one entrance for convenience.
I second this!
