"Clear the base, whatever it takes."
Crow's Nest is the third Campaign level of Halo 3.
Plot
The level begins with John-117, the Arbiter Thel 'Vadam, and Sergeant Johnson landing in an underground UNSC base.
When they disembark, several Marines are amazed to see a Spartan II. As they walk through hallways littered with wounded or crippled UNSC soldiers, Lieutenant Commander Keyes informs the Chief and Johnson that Truth has almost destroyed the UNSC Home Fleet, and only a few ships are left.
They soon reach the command center and speak with Lord Hood, discussing a plan for an all out attack on Truth's army.
