Crow's Nest

Crow's Nest is the second campaign mission of Halo 3.

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

Background
The level begins with the Chief and Johnson escaping from the African jungle and landing in an underground UNSC base. As they disembark, several Marines are amazed to see a Spartan. Commander Keyes then informs The Chief and Johnson of the current situation (that Truth has destroyed the UNSC Fleet, and only a few ships are left), all the while walking through hallways littered with wounded UNSC soldiers. They soon reach the Command Center and speak with Lord Hood, discussing a plan for an all out attack on Truth's army. However, the Covenant then jam the Humans communications network along with the rest of the base, shutting off the power. Truth then appears on the main viewscreen, threatening the Humans and telling them their world will burn. The Covenant then attack and the base "comes under heavy fire" from the Covenant Loyalists. Unable to sufficiently fight off the invaders, Miranda Keyes has a bomb placed in the operating room. Despite an attempt by the Covenant to disable the bomb, it goes off successfully, and all remaining troops, including the Master Chief escape into the base's garage where they survive the explosion.
