"Stage a one-cyborg assault and bring back the captain."

Keyes is the ninth level in Halo SPV3. In order to access the self-destruct codes to the Pillar of Autumn, Cortana suggests finding Captain Keyes in order to gain his neural implants. Cortana teleports the Master Chief inside the Truth and Reconciliation. John-117 must fight his way through the Flood to save the Captain before it's too late.

Overview & Background

Just like the Truth and Reconciliation, the level takes place aboard the ship and below a small canyon full of coolant pools. However, it's not only Covenant that is aboard, the whole level is full of Flood forms, and some Sentinels included. A new rank of Covenant is introduced after gaining the neural implants. This rank which applies to Elites, Jackals, and Grunts are known as the Special Operations. A new weapon, known as the Flamethrower, is also introduced.
