The quest That Lucky Old Sun is one of the most memorable side missions in Fallout: New Vegas, tasking players with restoring power at the HELIOS One solar facility. Navigating the complex choices at this location determines the power distribution for the Mojave Wasteland and unlocks powerful orbital weapons. Understanding the consequences of each option helps players align their choice with their chosen faction trajectory.
Arriving at HELIOS One and Meeting Fantastic
Upon approaching HELIOS One, players encounter NCR guards who direct them to the lead scientist, Fantastic. Fantastic presents a comical lack of expertise, forcing the Courier to assist in getting the solar plant back online. Speaking with Ignacio Rivas inside provides a contrasting, more responsible perspective on the facility's potential.
To proceed, you must activate two external terminals located within the solar reflector fields. These terminals are guarded by automated defense turrets and booby traps that require cautious navigation. Securing the passwords or using high Science skills allows smooth access to both systems.
Navigating the Solar Tower and Defense Systems
Once the field terminals are enabled, head inside the main solar tower to reach the mainframe. The interior is filled with hostile security robots and automated turrets that test your combat or repair capabilities. Utilizing energy weapons or pulse grenades makes clearing these corridors significantly easier.
Reaching the control deck presents a choice regarding how to handle the active mainframe defense system. You can choose to bypass the system using high Science or reprogram the defense grid to eliminate remaining hostile bots. Completing this step opens up the central power routing terminal.
Evaluating Power Grid Routing Options
At the central console, you must select where to divert the generated electricity from the solar arrays. Options include directing power to McCarran and the Strip, spreading power evenly to the entire Mojave, or powering Freeside and Westside. Each choice impacts your reputation with key factions like the NCR and the Followers of the Apocalypse.
Alternatively, players can trigger the ARCHIMEDES I defense system, which wiping out the NCR forces stationed outside. Routing power to the ARCHIMEDES II system enables the Euclid's C-Finder weapon for personal use. Choosing full regional distribution provides the most balanced social benefit across the wasteland.
Quest Completion and Long-Term Impact
After selecting your preferred power output, head outside to the top platform to manually trigger the solar panel realignment. Watching the solar reflectors align signals the successful completion of the restoration process. You can then report back to Ignacio or Fantastic depending on your final decision.
Your decision permanently shapes faction relations and regional development throughout your campaign. Aligning with Ignacio yields positive standing with the Followers, while favoring the NCR strengthens their hold on energy infrastructure. Completing this walkthrough ensures you maximize both immediate rewards and long-term strategic positioning.
