Arrowhead is the name of a map that was intended for release in a fifth DLC for Halo 4. The map would have likely been released alongside a remake of the map Narrows from Halo 3, and another map known as "ONI Bog". The map evidently would have taken place in or around a UNSC facility embedded in a cliffside, though no other details are known.
