The Cost was a trailer released as part of the Hunt the Truth marketing campaign for Halo 5: Guardians.[1] It was released alongside the Spartan Locke advertisement All Hail.


Spartan John-117 walks through the ruins of a destroyed city carrying an Assault Rifle. He steps over rubble as he makes his way to a large statue of himself. The UNSC Infinity is seen heavily damaged in the sky.

  • John: This... is this what you wanted? Is this what you were looking for? Was everything you've compromised, everything you've done—worth it? Was it?

John-117 sees Spartan Jameson Locke lying motionless at the base of the statue. Locke's visor is flickering and his breastplate has several holes. John holsters his Assault Rifle behind his back and unholsters his Magnum from his thigh.

  • John: You've completed your mission, Spartan Locke.

John points his magnum at Locke.

  • John: Mine is just beginning.

  • The large statue of John-117 in comparison to the All Hail trailer is more damaged as there is a noticeable crater on the helmet and the statue's frame is exposed on the left arm.
