Deadly thunderbolts

Sparkle's friend Twinkle was hunted down by Last Day soldiers serving under a new tyrannical leader. To track down and properly punish this fiend, we need to prepare with a needlegun modified to shoot paralyzing darts and then broadcast a message to the leader's PDA to lure them out of hiding.
==Walkthrough==
The first clue on Twinkle's body indicates that there is a PDA with instructions in the administrative building in Dead City.
=== Dead City ===
The PDA is in the envelope slots of an overturned desk on the first floor.
Picking it up completes the first thunderbolt. There are instructions on the PDA, but we shouldn't heed them just yet - reread the quest description, which indicates to first see Vasily in the Swamps and then Petrenko at the Bar.
=== Swamps ===
Talk to Vasily - after a short conversation about his health, Strelok asks for the late Kholod's modified needlegun. Vasily tells us that it's stored in a subterranean shelter just behind the bar, and ruminates on the life of his old friend. The second thunderbolt is complete.
Pick up the stash in the shelter, completing the third thunderbolt.
=== Bar ===
After a bit of attempted flattery, Strelok asks Petrenko if he can procure special paralyzing darts that can non-lethally disable their target. Petrenko is reluctant to proffer the information at first, but lets us know about a failed operation that was meant to capture multiple live mutants for a wealthy patron outside of the Zone. The would-be poachers disappeared near the swamp in Dark Valley. The fourth thunderbolt is complete.
=== Dark Valley ===
As you approach the southeastern side of the swamp, a music cue will play. The skeletal remains of the poachers can be found on the island in the water, and one corpse will be searchable. As you pick up the four Paralysing darts and the snork foot on the corpse, mutants will spawn in the general vicinity. The fifth thunderbolt is complete.
=== Agroprom ===
Now it's time to send the message. Twinkle's PDA denotes three areas with towers that are potentially the correct place for the signal - Agroprom, Dark Valley, or Army Warehouses.
You have to cross this corner of the watchtower in Agroprom precisely for the signal to go through. Strelok sets up a meeting in the Monolith Control Bunker and receives a confirmation that the message has been received. The sixth thunderbolt is complete.
=== Monolith Control Bunker ===
An ambush is waiting in Monolith Control Bunker. Last Day soldiers and white coats are set up all along the path to the C-Consciousness room, so advance carefully. Beware the Gauss-wielding armored trooper in the final room and pick up the note on the control panel in the room before.
After picking it up, the seventh thunderbolt is complete. Thunder promises to meet us in the Volkhov AA complex in Jupiter, warning us to come alone.
=== Jupiter ===
Thunder is alone in the room with the broken-down BTRs. Do not advance towards him, as you can softlock the quest. Use the Modified needlegun from long range to shoot him with a dart before he is aware of your presence. The eighth thunderbolt will complete, and you can speak to him while he is wounded.
Thunder will beg for his life to no avail. Dozens of friendly rats will spawn and eat his body - once he is dead, the final deadly thunderbolt will complete and the quest will be completed.
Beware three Brotherhood white coats who will spawn around the complex to cut off your escape.
==Notes==
* If Lightning was not killed in Bunker D-6 assault, she will appear instead of Thunder.
* If you softlock the quest by killing Thunder, Volazar will scold you before you are spontaneously killed.
