Get the Water Chip

Lore & Background

The water filtration system in Vault 13 was failing due to a missing component that had been stolen years prior. The Overseer discovered that the chip was not merely lost but taken by the Brotherhood of Steel, a faction obsessed with hoarding pre-war technology and viewing themselves as the guardians of civilization. This theft created an existential crisis for the vault's inhabitants, who faced imminent death from dehydration if the system could not be restored. The Brotherhood of Steel, led by Elder McCreedy (or his successor depending on the timeline), viewed the chip as a tool to be kept away from "savages" like the Vault Dwellers. Their ideology clashed violently with the desperate need of Vault 13, creating a conflict where technology was weaponized against survival. The quest highlights the tragic irony that the very group claiming to preserve humanity's future was actively condemning an entire population to death by withholding a simple piece of machinery.

In Their Own Story

The air in the vault tasted of recycled dust and fear as the Overseer called for the Vault Dweller. Outside, the sun beat down on a cracked earth where the only water left was poison or blood. The chip sat somewhere within the iron walls of the Brotherhood's fortress, guarded by power-armored knights who saw themselves as gods. With nothing but a makeshift weapon and a heart full of desperation, the Dweller stepped out into the wasteland. Every step toward the stronghold was a gamble; one wrong move meant death, but staying put guaranteed it for everyone back home.

Reader's Guide

The quest begins with an urgent directive from the Overseer to find the missing water chip. The player must travel to the Hub, where rumors point to the Brotherhood of Steel possessing the item. From here, three primary paths emerge based on the player's approach and stats. First, the diplomatic route involves negotiating with Elder McCreedy or his successor in the Stronghold. High Speech skills can convince them to return the chip voluntarily, sparing lives but potentially requiring a trade of other resources or technology. Alternatively, the player may attempt stealth, sneaking past patrols to locate the chip in the computer room or inventory without alerting the guards. If diplomacy and stealth fail, combat becomes necessary. The player must fight through the Brotherhood's defenses, engaging power-armored knights and their lieutenants to seize the item by force. Upon retrieving the chip, returning it to Vault 13 completes the quest, restoring water filtration. However, failing to retrieve it results in the vault's destruction or a tragic ending where the population perishes.
