Adrenaline is waiting for the couriers with weapon attachments, but all four of them have gone missing across the Zone. Helping him figure out what happened to them will lead you to the rest of the radios for Voronin.

## Walkthrough

After taking the quest, Adrenaline will mark four spots on the map where his couriers have been heard from last.

### Swamps

In the Swamps, the courier in the southwest corner of the map will turn into a Swamp bloodsucker as you approach and call out, so keep a melee weapon on hand. The weapon attachments for Adrenaline are in the backpack near him.

### Jupiter, swamp

The courier at the swamp is missing, apparently he was forced to throw his backpack into the water. Search for the backpack; besides the addons for Adrenaline, it will also contain a radio required by Voronin. Picking it up will force you to be rooted to the spot as you step into some sort of unknown anomaly, and Ratan will approach from all sides. Strelok makes a call for help over the public channel, and eventually two Hunters answer and approach to help you fend them off. 5000 RU is given to each of them after the ordeal is over for their help.

### Jupiter, train tunnel

The courier in the northwest section of the map will be inside the train tunnel. Thoroughly clear the area from the usual spawn of zombies and controllers before moving into the tunnel.

As you approach, the courier will turn out to be a Hunter-controller, and a host of controllers leading their zombies will spawn outside in the tunnel. This includes a Psionic, Pyro-controller, Chasing-controller, Plague zombie, Mosquito zombie, Fat zombie, Exploding zombie, another Grandmother-controller, two Zombie hunters, and several regular zombies as well.

### Zaton

The testing facility in southwestern Zaton has a courier squatting over a backpack on the lower level of the Gauss testing facility. On approaching, it will turn into a Grandburer. More burers and poltergeists will spawn outside of the laboratory and make their way in to give you a hard time as you try to escape.

### Back to Adrenaline

Return to Adrenaline with all of the weapon components from the backpacks. He will give you the remaining three radios you need for Walkie-talkies for Duty, and Strelok will take a drink to calm his nerves.

## Notes

* The backpack in the Jupiter swamp contains a radio, but none of the others do, which could be a source of confusion for people expecting each courier to have one of the radios they need.
* "Typhoon" Turret is useful at every stage of this quest, since the vast majority of enemies you face are mutants, but especially so in the Jupiter steps.

## Bugs

* Sometimes only one of the hunters will come to the riverside to assist in Jupiter.
* Sometimes the hunters will walk off instead of helping.
