New Vegas Youll Know It When It Happens Quest Walkthrough

Protecting President Aaron Kimball during his visit to Hoover Dam is one of the most critical security assignments in Fallout: New Vegas. The quest requires careful observation and swift decision-making as multiple assassination plots unfold simultaneously. Navigating this mission successfully ensures that the New California Republic maintains its leadership intact during a vital turning point in the Mojave region.
Preparing for the Security Sweep
Before President Kimball arrives on his Vertibird, players must report directly to Ranger Grant to receive official clearance. Requesting permission to inspect all restricted areas grants full access to the site without triggering hostile reactions from NCR guards. Conducting an early inspection of the visitor center lobby and nearby supply closets allows you to discover crucial physical clues ahead of time.
Neutralizing the Vertibird Bomb
One of the primary threats involves an explosive device attached directly to the president's transport vessel. Players equipped with sufficient Explosives or Repair skills can inspect Bear Force One and safely disarm the charge before the speech concludes. Alternatively, pickpocketing the disguised engineer in the landing area can yield the detonator needed to prevent the blast.
Stopping the Legion Sniper
A second threat emerges from the observation towers behind the main stage. A Legion operative disguises himself as an NCR Ranger after overpowering the original guard posted at the top of the tower. Climbing the ladder quickly allows players to eliminate the hostile sniper before he takes his shot.
Handling the Ground Assassin
If the speech continues without early evacuation, a final assassin will rush toward the stage armed with a melee weapon. Vigilant players must intercept this operative disguised as an NCR engineer before he reaches the podium. Eliminating all three threats safely secures President Kimball's departure and concludes the mission successfully.
