- "All hail the conquering hero."
- —Jameson Locke
The Halo 5: Guardians Spartan Locke Ad, also called All Hail, is a video advertisement which is part of the Hunt the Truth marketing campaign for Halo 5: Guardians. Released on March 29th 2015, it depicts Spartan Locke confronting the Master Chief on a ruined planet. It was aired along with the Master Chief Ad, which features similar circumstances with the characters' roles swapped. Both trailers were directed by Rupert Sanders, who previously worked on the Believe campaign and the We Are ODST live-action trailer.
This trailer marks the first appearance of the official release date of Halo 5: Guardians; October 27, 2015.
This trailer, along with The Cost, was taken down by Xbox on its YouTube channel on April 22, 2016.
Jameson Locke stalks through the bombed out ruins of a building. He emerges into the open air in the midst of a large debris field on an unknown Human colony world. Severely damaged skyscrapers still stand in the distance.
- Locke: "All hail the conquering hero."
He turns toward a pitted and scarred stone statue of Spartan 117 and begins walking toward it. A damaged UNSC Infinity can be seen floating in the sky.
- Locke: "Let us remember him as a protector and not the one who gave us..."
Locke outstretches his arms to gesture to the devastation surrounding him.
- Locke: "...This. As our savior, and not our betrayer!"
As he speaks, the point of view briefly switches to Locke's as he looks through his helmet's faceplate.
- Locke: "Let us see him forever, as you. And not as you."
As Locke says "you" for the first time, he gazes upward at the statue, representing the idealized image of John-117 as the hero and savior of humanity, with the quote "Duty and Honor Above All" below. He then looks down to the figure below the statue; the real Master Chief, lying in the dirt appearing badly injured, armor still sporting a smoldering hole in the chestplate. Locke drops his rifle, and releases the magnetic locks holding his pistol to his armor, which flies into his hand. He points it at the Chief's head.
- Locke: "All hail the conquering hero; the one who was supposed to save us all! But now I must save us from you."
Locke is holding an M395 DMR in the trailer, but his HUD shows he has a BR85HB battle rifle.
