Complete Call of Duty 3 Hunter Killer walkthrough. Find intel, plant the bomb on the sub, and navigate the naval mines.

Walkthrough
  1. 1
    Move through the tunnel, avoiding rubble.
  2. 2
    Once clear of the tunnel, avoid the naval mines by staying with your allies and following their directions.
  3. 3
    Reach the submarine, move to its side, and press X to plant the bomb.
  4. 4
    After the explosion, board the submarine and quickly eliminate the soldiers on top.
  5. 5
    Sandman will throw a frag grenade, allowing you to enter the submarine.
  6. 6
    Drop down the ladder and wait by the door.
  7. 7
    When the door opens, shoot the two enemies across the room.
  8. 8
    Head down to the end of the room on the right to find Intel 1/2 on a bunk in the last aisle.
  9. 9
    Proceed down the stairs. Move to the left and watch for guards in the closed-off section of the room.
  10. 10
    Watch your corners for enemy soldiers, as a melee attack (a close-range attack from an enemy) is a one-shot kill.
  11. 11
    Ditch your pistol for an enemy's PP90M1, as it is effective at close range and ammo is plentiful.
  12. 12
    Head up either stairway on the other side of the room.
  13. 13
    On veteran difficulty, clear the two-floor grid of corridors. Enemy soldiers often use lasers on their guns, which helps locate them.
  14. 14
    Kill the soldiers at the door, then enter and branch right.
  15. 15
    Go up the stairs and go prone (lie flat on the ground) at the top.
  16. 16
    Move left and shoot the soldiers coming through the door.
  17. 17
    From the elevated position, pick off the remaining soldiers below.
  18. 18
    Be aware that soldiers from the next room will shoot through the door.
  19. 19
    Intel 2/2 is found from the top of the stairs: turn left, touch the wall, follow it left, and the intel is at the end of the catwalk next to a wall.
  20. 20
    In the next room, stay prone at the entrance and eliminate the soldiers guarding the choke point.
  21. 21
    The objective door is on the second floor, so do not go downstairs.
  22. 22
    Stack up on the last door on the right to breach it.
  23. 23
    When you breach a door, the game enters slow-motion for a few seconds.
  24. 24
    Shoot the enemy charging at you with a knife, then sweep the room from right to left.
  25. 25
    With the room clear, head to the console and activate it.
  26. 26
    Go up the stairs and drop over the side into the boat.
  27. 27
    Control the movement of the boat, staying with the other zodiac (a type of inflatable boat).
  28. 28
    When an enemy boat attempts to board, shoot the red spheres at the back of their ship.
  29. 29
    Continue on and drive the boat onto the back of the helicopter to end the mission.
Tips
  • The PP90M1 is recommended for its effectiveness at close range and plentiful ammo.
  • Shotguns, specifically the Striker, are effective in this mission due to the tightly packed areas, despite their reduced effectiveness in other Call of Duty 3 scenarios.
  • When clearing rooms, watch your corners for enemies, as melee attacks are instant kills.
  • On veteran difficulty, using the elevated positions after going prone at the top of stairs can help clear rooms more easily.
  • When breaching a door, be prepared for the slow-motion effect and quickly eliminate threats.
