Pierre is the head "former" scribe and engineer of the Rim. He's been tasked with creating a better filtration process to make the irrigation water drinkable.
He'll ask the player if he sees anything in the wasteland that could help, he would appreciate the feedback. He'll suggest the player go to Jericho since that is where they get most of their drinking water from. The player can then go to Jericho, do his thing there and hopefully get some filtration schematics out of it (Jeff H.). Coming back to Hoover, the player can do one of two things, depending on his skills: The first is if the player has really good mechanics skills. The player may then install the upgrades to the filtration process and earn the hooplas of Pierre, along with an advanced tool kit (or whatever the best toolset is in the game).
The second option is to just give the schematics to Pierre and let him deal with it. He'll get the upgrades in, but the player will have to be content with the XP, a regular tool, and Pierre just being a bit friendlier. Who knows, maybe he'll divulge the whereabouts of Maxson's bunker?
Character type completion breakdown
- Combat, Dipomacy, Stealth Boy - Simple fetch quest, nothing to kill unless the player is psycho.
- Science Boy - Get a bit of a bonus if the player is able to do the upgrades himself using the schematics.
