Sound signal

For the Minigun, Full-bird wants you to find a device lost over Wild Territory.
== Walkthrough ==
Talk to Sakharov; he already built a specialized detector that gives a signal while in proximity of the device. Receive the detector, and go to Wild Territory. Turns out you aren't the only one looking for the device; a team of 8 mercenaries is also searching for it. Kill them and continue the search.
The "device" is actually a video tape, and can be found in one of 9 places:
After grabbing it, move out to Sakharov to find out that mercenaries blocked both the road to Yantar and back to the rest of Wild Territory. After crossing a point just outside of the Burner tunnel on the Yantar side, they will spawn a squad at a time and slowly come at you from both sides. 26 mercs total will come from the main Wild Territory and 20 from the road to Yantar.
Kill all mercs and proceed to Yantar. Bring the tape to Sakharov and get your minigun that you can get back to Adrenaline.
== Notes ==
* Like with the other large fights, trying to be a smartass and ignore the mercs by running through, or making your way around the tunnel restrictor via other locations will only complicate further walkthrough, and can lead to things like being instagibbed on entering the location, or quest conflicts. Always finish your fights and wipe out your enemies.
* Trying to bypass the mercenary ambush by going out of bounds to move around them to the Yantar transition point will trigger a scripted unblockable sniper event that will kill you after a few seconds even if you try healing through it. Happens even if you climb on top of the tunnel exit.
* Similar to the Missing expedition ambushes, the encounter is significantly easier if you double back after triggering the spawn and negate the pincer attack by breaking through on the Wild Territory side. It is extremely rare that any mercs from the Yantar side will come all the way through the Burner tunnel, so you are free to take on one side at a time.
== Bugs ==
* For certain spawn variants, detector doesn't emit any sound.
* In certain circumstances, the cassette (the device) can fall through the ground, becoming unobtainable. Leaving and reentering the location should fix that.
