Tsavo Highway

Tsavo Highway is the third campaign mission of Halo 3.

It starts with SPARTAN-117 in a ruined UNSC base outside of Voi, who mounts a Troop Transport Warthog and skirts by the destroyed New Mombasa Space Elevator, and then reaches Tsavo Highway, encountering blockades of occupying Covenant Loyalist Brutes, Jackals, and Grunts, until reaching the terminus: the Ark, where Covenant Cruisers vaporize the surface of the Earth, unveiling the Ark.

Upon completing it on the Normal, Heroic, or Legendary difficulties, the player will earn the "The Road" achievement and 20 Gamerpoints.
