Hard Luck Blues - Fallout: New Vegas
QUEST REWARD: 100 EXP (150 possible), NCR Fame
1. Investigate the East Pump Station.
2. Find the source of the Radiation.
3. Shut down Vault 34's Reactor to help the Sharecropper Farms.
(Optional) Save Vault 34's trapped dwellers by leaving its Reactor intact, dooming the Sharecropper Farms.
Head to the main gate at the Sharecropper Farms to meet Private Ortega. After conversing with her talk to Morgan Blake near the picnic tables and ask her what's going on to start the quest. Head east to the Pump Station and check out the terminal to discover a radiation leak in Vault 34 is causing food to be radiated. Follow the quest marker to Vault 34 and beware the Golden Geckos that lurk nearby. Once you enter you will soon realize that all the vault inhabitants have become Ghouls and the area is highly irradiated.
The best way to navigate through the vault is to follow the signs on the walls to get where you need to go. Begin to descend following the signs to the Over-seers Office until you reach a fork where there are only two signs, each pointing to the right labeled Overseer's Office and Clinic. This should put you at the far west side of the local map. At this juncture go west and into the water until you find a dead Vault Technician. Loot the [VAULT 34 UTILITY TERMINAL PASSWORD] from him then make your way to the far east side of the local map south of a door to the armory. Dive into the water here and perform the same act of retrieving another [VAULT 34 UTILITY TERMINAL PASSWORD].
Emerge from the water and enter the nearby Utility Room. Active the terminal and drain the steps you just swam down. Head down the steps and go through the Security Station to the Armory. Descend until you reach a terminal near the [OVERSEER's JOURNAL FRAGMENT] and disengage the Overseer Office lock. Return to the first floor and follow the signs to the Overseer's Office where you must kill his ghoulish form and loot the [OVERSEER'S PASSWORD] for his terminal.
Unlock the gate and descend to the Reactor. Check the terminals nearby for a warning then make your choice to either seal the ventilation system or reroute control of the Vault. The former ends the quest granting [100 EXPERIENCE POINTS] and NCR Fame whilst the other destroys the NCR Sharecropper Farms, gives [150 EXPERIENCE POINTS], and save the Vault Dwellers.
