If you needed any more proof that the ominous-looking bunker in Gray Zone Warfare is an unpleasant place to be, then this is tangible evidence you'll need to find as part of the Deep Depravity task.

Deep Depravity is a late-game task offered by the vendor Banshee. Banshee tasks you with following up on "some really nasty rumors" about the Soviet bunker that the locals called "The Hole." You'll have to delve deep into The Hole to find the evidence you seek.

To get to the information alive, you need to know the best way in and where to find information about Gray Zone Warfare atrocities.

The intel of atrocities is located in the basement of the second floor of the YBL-1 bunker south of Fort Narith, in the side office of a conference room. The entrance to the bunker, which you probably know after completing the New Neighbors, The Negotiator and the Prisoner 23 tasks, is located at map coordinates (142, 121).
