Fix the mine's air purifier
The broken air purifier
Our air purifier's broken. It's on the bottom level. We've got no parts, and we've got no protective equipment. Without the parts, we can't fix it. Without the protection, the radon gas'll nail us. Are you any good with your hands?”— Zaius
|Side Quest: Fix the mine's air purifier|
|Speak to Zaius.|
|Travel to New Reno and speak to Renesco about the part.|
|Go back to Broken Hills and speak to Zaius.|
|Repair the air purifier.|
|Report back to Zaius.|
|Reward: 1000 XP, a combat shotgun or 500 dollars|
Talk to Zaius inside the house outside the Broken Hills mine's entrance. He will tell the Chosen One the mine needs parts for the air purifier and asks him to go to New Reno to pick them up. He can either take the reward for money, or decline and receive a combat shotgun when finishing the quest.
Return to Zaius and he will ask the Chosen One to enter the mine to fix the purifier. The mine is filled with radon gas, which will damage the Chosen One and his party for about 5 points of damage every few steps. If the player character or any of his followers have power armor equipped, it will negate the damage. Use the parts on the clanking machine in the back (But watch out for the deathclaw!) for 1000 XP.
The Chosen One can actually avoid the damage from the fumes without having to wear a set of power armor. For that, one has to keep saving every few seconds, and every time the player character gets damage, load the savegame. By doing so, the interval between one charge of damage and the other will be reset, and the Chosen One will have more time to push on.
Return to Zaius and he will give the Chosen One a City-Killer combat shotgun or $500 if he asked for a reward earlier.
