Tears of Yantar

Sakharov needs Tears of Electra, Tears of Fire, and Tears of the Chimera for Elsa's final treatment. He may also have information for us based upon his analysis of the dictaphones.
== Walkthrough ==
=== Yantar ===
Give Sakharov the artifacts and he will thank you again. More importantly, he's concluded his analysis of the dictaphones. Each one was recorded at a certain point on Strelok's original journey north, leading Sakharov to the conclusion that the next recording will take place in CNPP-2.
Sakharov warns you about fighting Murzo head-on as he still wears the immortality artifact Living Water. He gives us a Poltergeist's Heart to even the odds as well as a Monolith teleportation device to quickly get to CNPP-2. The quest is closed.
=== Fighting Murzo in CNPP-2 ===
This encounter is somewhat nonstandard. Murzo cannot be killed, but will be forced to teleport whenever we shoot him. You do not need a high damage rifle to cause this to happen. After he teleports, more enemies will spawn and we will have to hunt him down again.
After clearing the area of controllers, drop down to the overpass. Murzo is near the crashed helicopters below.
After triggering his teleport, Monolith tanks and one invisible trooper spawn below in the starting area.
Keep going through teleports until you reach the roof. Murzo is near the Monolith Control Bunker transition with several clowns, who will fight the local mutants. You may need to drop down to shoot him if he doesn't expose himself.
At the next flash, clowns are spawned on the lower terraced section of the roof. Murzo is near them on the east side.
Continue going through teleports. From the teleport on the roof, run directly towards the building and climb the ladder to the teleport near the wall. You should clear clowns whenever you have a good angle to shoot at the overpass. There will be a large group of clowns both above and below, with Murzo on the ground level. Beware if you are on an overpass currently, the flash will spawn one clown behind you.
Go through the next teleport. Take out the controller that spawns near you, and look west to take out Monolith tanks that are firing at you from below. The clowns will be on the building to the north. You might want to take them out and shoot Murzo before jumping down into the next teleport.
On the other side of the overpass, one clown will be waiting for you. Teleport again.
Hop to your right onto the building and get across the broken pipeline. Run across and teleport twice, and beware another clown waiting for you on the overpass. The rest of the enemies are not hidden and will be directly on the combat path.
Take out four clowns and Murzo will be right behind them on the next section. Teleport again.
The supply crate section will have six clowns flanking Murzo.
After the Sidorovich teleport, beware an invisible Monolithian directly in front of you when you exit the teleport. Six tanks will be not far behind along with Murzo.
After teleporting to the final area, drop down and run behind the building. Murzo will have dialogue for you, threatening both Elsa and Doctor. He will teleport away, leaving Chessplayer's Teleport and Chessplayer's Dictaphone No26.
"You're as naive as a child... Pavlik Dukh, Ivantsov, Kalancha, Frost... and now Sakharov and his sick wife... She's going to die... this will be my next victim, which I'll kill with an others' hands... Your hands! The Colchamine is not colchicine at all, but a drug that we smuggle under the guise of medicine to the Big Land... Hello, stupid... Goodbye, ugly Elsa!"
Playing the dictaphone opens Ugly Elsa. The Colchamine we gave Elsa was not what it appeared to be - it was the fully developed version of the Brotherhood drug disguised as a simple chemical component! We need to rush back to Yantar to warn Sakharov.
== Notes ==
* Murzo himself is not a big threat. He wields a Kalter's VMK that can be bought from him during dialogue for about 100,000RU.
* Brotherhood clowns are unarmored and can generally be taken out with one smallbore rifle bodyshot. Watch out for the ones carrying RPG-7s.
== Bugs ==
* As counterintuitive as it sounds, do not use a high damage weapon to attack Murzo. He will often simply die without teleporting away, softlocking the storyline.
* Murzo's Brotherhood clowns will fight the local mutant spawns and often die to them. This is likely unintentional.
