Tsavo Highway

Tsavo Highway is the third campaign mission of Halo 3.

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

It is the first Halo 3 campaign mission to feature useable vehicles

Background
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. It is unknown if the Arbiter will be in this level in single player.

Trivia

 * Tsavo is a region of Kenya close to where the Tsavo and Athi rivers meet and was the place where the Uganda Railway passed over the Tsavo river. There is a chance that a bridge will be encountered at one point.


 * In an article on IGN, it is said that Cortana's voice-over tells you about the stranded transport team. Cortana's voice may have been used just for demo purposes.
