Crumb the deal

One of Sakharov's precious scientific journals has fallen into the hands of a defector, who plans to sell it off to the military. Glimmer Man entrusts you with a long-distance sniping mission to Jupiter, where the handoff is happening. All parties must be eliminated from an extreme distance with the exception of Lieutenant Morozko. Glimmer Man gives sends his picture to your PDA.
== Walkthrough ==
=== Cordon ===
After accepting the mission from Glimmer Man, talk to Kuzka's Mother for some supplies. The quality of the ammo should give you an idea of the distance you'll need to be hitting your targets at.
=== Crumb the deal ===
Grab the longest range rifle you have (Gauss rifle with computerized targeting is recommended), and head over to the [ Jupiter cement plant]. (it's marked on your PDA map)
Clear out all zombified stalker and Monolith spawns from the area before ascending the sniper nest - these can distract your targets if ignored.
Make your way up the stairs, at the top of the tallest building. Once you reach the top, about 15 zombified stalkers and a Mosquito zombie will spawn below you once you reach the sniper nest. Adjust your position accordingly so that none will be able to hit you from below, since they cannot climb the ladder.
After about two minutes of waiting, a helicopter will arrive and drop the military off. One of them is Morozko. Look at the photo Glimmer Man gave you (in the task description in your PDA), and remember how he looks, as you have to keep him alive. Soon, you'll see the scientists arriving on feet to make the deal with the military.
You will have two minutes as they negotiate. Kill everybody except Morozko, and your mission should update with a notification.
Keep track of your targets with this list:
* Military:
** Major Assholov
** 2 soldiers in exoskeletons, guarding the helicopter
** 2 soldiers in SKAT-10s
** 1 soldier in a camouflage exo
* Ecologists:
** Liberman, in a green ecologist suit
** Orange ecologist suit
** Ecologist exoskeleton
** Scientist exoskeleton
=== Recovering Sakharov's notebook ===
You can either slowly clear out the factory or simply jump off the edge. Get to the meeting site and grab the notebook from the body of Shmuel Liberman; be careful of the eight counter-snipers stationed along the way to the deal. Don't worry about Morozko, he won't attack you. Besides the notebook, be also sure to pick the PDA from the body of Major Assholov - it contains the info on the transition from Jupiter to Zaton.
=== Escorting Morozko ===
After collecting the notebook from the defector's body, Glimmer Man will thank you and ask you to escort Morozko out of Jupiter in the mission Collective trip.
=== Return the notebook ===
After escorting Morozko, bring the notebook back to Sakharov at Yantar for your reward.
== Notes ==
* Descending from the rooftop results in a scripted sniper shot every few seconds until you die. It is unknown if what happens if you survive this repeatedly with something like the upgraded SKAT-15's healing ability, but you will likely run out of time to take out your targets.
** The girders in front of the rooftop can be jumped on without quest consequences, but any counter-snipers and zombies below you may start shooting at you.
*Any direct hits or ricochets impacting the helicopter will cause it to immediately aggro to your position with rockets and machineguns. You can take it down with a loaded PTRD since it is vulnerable after unloading, but you should probably reload your save to avoid the time loss.
* The counter-snipers stationed around the map can be shot whenever you wish, even before the deal happens.
* Mines and other explosives are offline at this range, and will not be any help to you.
* An anomaly capsule dropped on the staircase will prevent any zombies from making their way up and harassing you.
* Glimmer Man warns you not to shoot too early, to ensure all parties arrive. However, you can start shooting the military as soon as they disembark, which runs the risk of them running off into the sunset when they are unable to find a target. The ecologists will still run to the meeting point normally.
* Liberman holds a relatively rare SIG SG-550 "Camo" with a scope and silencer attachment.
* The Idol of the Monolith artifact from the Diamond skulls can be helpful to clear the weather and see the targets better, or even temporarily switching to Static Lighting in the video options.
== Bugs ==
* Morozko will sometimes move towards your position after the main targets have been dealt with and help you deal with the zombified stalkers and the Mosquito zombie. He appears to have enough health to fend for himself, so don't worry about him dying.
