The Lucky Old Sun New Vegas Quest Walkthrough And Choices

The quest That Lucky Old Sun in Fallout: New Vegas presents players with one of the most memorable dilemma-driven side missions in the game. Located at the iconic HELIOS One solar power plant, this mission tasks players with restoring the facility's power grid while deciding who benefits from the energy produced. Navigating through the complex solar facility requires a mix of exploration, terminal hacking, and combat against defensive systems.
Starting the HELIOS One Mission
To begin the quest, players must head to HELIOS One and speak with Fantastic, an incompetent NCR contractor stationed inside. He explains that the solar facility needs to be reconnected to the mainframe so power can be distributed across the region. Before interacting with the central systems, players can also talk to Ignacio Rivas, who holds a different vision for the plant's resources.
Navigating the Reflector Field and Mainframe
Players must head outside into the solar reflector field to configure the western and eastern control terminals. Once the terminals are active, entering the main tower requires dealing with automated security turrets and repair bots. Restoring the auxiliary generator inside allows full access to the HELIOS One mainframe terminal.
Choosing the Distribution of Power
At the central computer terminal, players face the critical decision of where to route the generated electricity. Options include directing power to the NCR military bases, local communities like Freeside and Westside, or spreading it evenly across the region. Alternatively, players can divert power to the ARCHIMEDES II orbital weapon system, which unlocks a powerful weapon targeting option.
Completing the Mirror Realignment
After selecting an output destination on the computer console, head to the upper observation deck. Players must flip the control switch between 9:00 AM and 3:00 PM when solar energy peak performance occurs. Once the reflectors realign and complete the power transmission, report back to complete the quest and earn reputation rewards.
