Chemical equilibrium

Akill's part of the information on the Gauss pistol prototype is hidden inside Pripyat-1 Underpass, but it can't be accessed because there's a dangerous Venom that has unusually strong regeneration capabilities to be taken down with weapons alone. The Venom has to be poisoned using chemical weapons. You need to find heavy canisters with the gas in the Jupiter ventilation complex, and tag each one with a GPS tracker, so Akill's people could drag them into the Underpass later.
== Walkthrough ==
Head over to the [ Jupiter's ventilation complex]. It will have German mercenaries above and around it and a host of deathclaws on the inside. A turret will also be camping at the entrance to the complex underground.
The second turret is overlooking the surface part of the complex. There is technically no need to interact with the mercenaries and one turret above if they don't aggro to you, but the place should be cleared regardless.
All canisters are hidden in the underground section of the complex. Here's a video with the location of all of them. Pay attention to the jump at 2:04, which is easier to perform towards the rusty beam to the left; this is a tough crouchjump if you don't carry jumping artifacts.
After tagging certain canisters, more deathclaws will spawn into the underground to harass you. Tag all 8 canisters and return to Akill for the next step.
== Notes ==
* Akill supplies you with all 8 beacons you need, unlike most other tagging quests.
* A crowbar, even one in only semi-decent condition, will take care of any deathclaw in one hit. Keep it on hand while tagging so that you can bash your way out of the situation.
* You will carve a lot of Deathclaw Horns as a result of this quest, which is a good way to stockpile for The monsters' parts if you haven't completed it yet.
* While visiting Pripyat-1 Underpass, the venom is nowhere to be seen as it will only spawn in the next quest; this is an oversight.
