Follow this comprehensive Halo: Reach walkthrough to navigate the treacherous Flood-infested halls, rescue Cortana from the Gravemind, and escape the collapsing Ark.

Walkthrough
  1. 1
    Continue through the infested hallways, following the waypoint. You'll hear child Cortana speak.
  2. 2
    In the next large room, you'll encounter the Flood in their Range form. Head upwards, using platforming elements to ascend. Clear the room of Flood before proceeding.
  3. 3
    Look for the Brute Shot weapon in this room; it's effective against wall-clingers.
  4. 4
    To climb, jump onto the large purple box in the center, then to the metal platform opposite. Continue ascending via platforms and jumps across chasms.
  5. 5
    Navigate ancillary hallways uphill until you reach another chasm before a sphincter at the top.
  6. 6
    Proceed through the next hallway and sphincter into a giant room with a hollow central column, infested with spider-form Flood.
  7. 7
    Use the Brute Shot extensively here. Its melee blade is effective against Tank-form Flood, and shots work well against Range-form.
  8. 8
    Circle the perimeter to a bridge leading to a central island.
  9. 9
    From the center, cross a flesh bridge to reach a door.
  10. 10
    Continue through the next door where Cortana admits she is a monument to your sins.
  11. 11
    In the subsequent room, a distressed Cortana is found within a bubble. Melee the bubble to free her.
  12. 12
    Cortana reveals she still has the activation index. The Gravemind reclaims her and absorbs her into his being.
  13. 13
    Cortana, now back and angry at the Gravemind, begs to be freed.
  14. 14
    Return to the central chamber. Cortana suggests initiating a chain reaction to destroy the ship by overloading the propulsion system.
  15. 15
    Activate the console on the central island, then destroy the four other towers indicated by navigation icons.
  16. 16
    The chambers will explode, initiating an escape sequence. Wait for an explosion to clear the escape path, which Cortana will mark with a nav icon.
  17. 17
    Follow the marked path, which involves backtracking through a previously visited area, until you reach the Pelican.
  18. 18
    Board the Pelican with the Arbiter to escape the Gravemind's tendrils.
Tips
  • The Brute Shot is highly effective against Flood, especially wall-clingers and larger forms.
  • Pay close attention to navigation icons during the escape sequence.
  • The backtracking section requires careful navigation; follow the nav points provided.
