Meet Kruglov

After making your way to Wild Territory, you discover a team of scientists in a shootout with mercenaries; they are calling for help over radio.
== Walkthrough ==
=== The simple way ===
Kill the mercenaries and their leader Wolfhound. Talk to Kruglov, starting Escort Kruglov to Yantar which is the second part of this quest.
=== The hard way ===
The four scientists accompanying Kruglov aren't required for the quest, but can be saved nonetheless. This will yield the Guardian Angel achievement and a Living Heart artifact, that can be used later to resurrect Chemist in Inferno.
Note: it's probably best if you grab an RPG-7 before entering the Wild Territory the first time to make the subsequent quest easier, although it's not necessary.
Saving all four scientists is notoriously random, and considered one of the hardest things in the game by many; players tend to solve this in overly complex ways like exploiting OOB areas or reloading a hundred times. However, there's a clean and easy way to do this every time, if you do everything right.
* As you hear the gunfight, climb this ladder and run along the double pipe towards the scientists. 
* Throw a grenade towards the mercs; they are behind two reservoirs. This will make them panic for a while, buying you some time. 
* At the end of the pipe, kill a merc by the locomotive who is going to flank the scientists. 
* Finish off the rest of the mercs, including Wolfhound.
* Check that all 5 scientists (Kruglov and his team) are alive.
* Wipe the entire Wild Territory from any enemies, to make the next quest much easier. Pay attention to electro-chimeras in the collapsed tunnel as well.
* Talk to Kruglov, starting Escort Kruglov to Yantar which is the second part of this quest.
Here's a video demonstrating this. Warning: grenade panic trick isn't shown, and it's really the key to this achievement. With a grenade thrown at mercs, scientists sometimes even kill them on their own, without your help.
== Notes ==
* Wolfhound's PDA is useless after getting the recipe, and can be given to Sidorovich in a cyclic quest.
* Vortex anomalies in the Burner tunnel can be sprinted through. They will be disabled later, in Escort Kruglov to Yantar.
* The Music flash card №12 you can find on Wolfhoud's body is required for Max Lyuber's chain quest. It can also be used in the MP3 player you can buy from Sidorovich and Barkeep, provided you have music packs installed.
