The quest That Lucky Old Sun in Fallout New Vegas presents players with one of the most intriguing moral and tactical dilemmas in the Mojave Wasteland. Situated at the HELIOS One solar power plant, this mission forces Couriers to decide how energy from the massive facility should be distributed. Understanding the consequences of each choice helps players align their decisions with their overall character build and faction preferences.

Routing Power to Factions and Local Communities

When interacting with the mainframe terminal, players can direct power to specific regions or across the entire grid. Routing power exclusively to McCarran and the Strip earns substantial reputation with the New California Republic. Alternatively, sending power to Freeside and Westside grants reputation with the Followers of the Apocalypse, as well as access to a valuable Big Book of Science skill book.

Weaponizing HELIOS One with ARCHIMEDES II

Players who choose to divert power to the ARCHIMEDES II satellite unlock a unique orbital laser strike. By purchasing Euclid's C-Finder from a young boy in Freeside, you can call down targetable orbital bombardments once per day. While visually impressive, this weapon option offers limited tactical utility due to its single-use restriction per day and modest blast radius.

Activating Defense Systems and Regional Consequences

The terminal also features an option to activate the ARCHIMEDES I defense system prior to retargeting the grid. Enabling this protocol unleashes a lethal strike against the local NCR personnel guarding the facility. Players seeking a balanced outcome often choose full grid distribution, which provides a skill book reward without provoking hostile reactions from major factions.

Choosing the Best Path for Your Playthrough

Evaluating the optimal choice depends heavily on your endgame objectives and companion interactions. Siding with the Followers or electing full regional power distribution provides long-term skill benefits for science-oriented builds. Regardless of the outcome chosen, navigating this facility remains one of the standout quests across the Mojave region.
