Vernitsky's report

Katana reveals that the reason mercenaries have been attacking the camp so relentlessly is a legendary scientific report rumored to be hidden in X-14 Laboratory below Kurchatov-37. Your job is to find the report and deliver it to Professor Lutsenko in Scientific Station to take the pressure off of the Furies.
== Walkthrough ==
Descend into the X-14 through the newly obtained transition. After walking through the tunnels for a while, you'll enter the lab itself.
Inside, you'll see the storage room with a safe and several zombies.
One of the zombies in the white scientific suit is Assistant Gumiljov. Make sure to loot his PDA with the info on the transition to Scientific Station, otherwise you won't be able to exit the lab!
Approaching the safe will spawn four Underground Bloodsuckers. One of them will spawn behind you and throw you into a scripted grab attack. Avoid this by running up to the safe and jumping on top it or any of the boxes in the room. The bloodsucker and its three friends will be unable to reach you, and you can whack them with a melee weapon when they approach.
Grab Vernitsky's report from the safe. Continue through the subway tunnels to reach Scientific Station. Find Professor Lutsenko at the [ scientists' bunker], and bring him the report.
== Notes ==
* The Underground bloodsuckers are rare mutants and will drop Red Bloodsucker Tentacles if you're lucky.
* The exit side of X-14 has an invisible one-sided wall that blocks the passage in the reverse direction, so the entire location can only be entered from Kurchatov-37 and traversed through to Scientific Station, not vice versa. Moreover, the exit transition can only be obtained from Assistant Gumiljov in the lab. If you don't loot him and proceed to the exit, you will lock yourself behind that invisible wall.
* After turning in the quest, Lutsenko will have the best prices for Black Energy (750 RU), Scientific first aid kits (1240 RU), 7.92x57mm ammo (3000 RU), GPS beacons (973 RU), and M209 charges (960 RU)
*The underground bloodsuckers look similar to the canceled S.T.A.L.K.E.R. 2 build's bloodsuckers.
== Bugs ==
* The safe can only be interacted with precisely on the dial, or from an exceedingly specific spot after jumping on top of it. This could be a bug, or it could be an intentional misdirection to force the player into getting grabbed by the bloodsuckers.
* After being grabbed by the bloodsuckers, the UI may disappear and fail to reappear. Press the Num + button to toggle it back on.
* Service ladder at the exit of the tunnel might be blocked by a green box if a poltergeist tries to play with it. It's a physical object - try pushing it with your head, or shoot it with a shotgun to give it a kick.
* Even when 100m underground inside a Scientific Station bunker, the Avengers in Scientific Station can and will fire underbarrel grenades into the complex from the outside and hit you.
