Walkthrough
  1. 1
    Head through the door and to the far end of the walkway. Stealthily take out the guard from behind.
  2. 2
    Crawl underneath the opening around the corner and stealthily kill the second guard by taking cover behind the wall and performing a melee attack as he approaches.
  3. 3
    Go into the room near the forcefield, crawl to the adjacent room, and stealthily take out the Neo-Umbrella J’avo guard.
  4. 4
    In the hall, take cover against the door and wait for the guard's shadow. Move in for a stealth kill as he moves away.
  5. 5
    Wait for the guard behind the next laser field to walk away, enter the next room, and kill the guard. He will transform, so use a normal arrow to spike him against the wall, then use a melee attack.
  6. 6
    Crawl through the vent and shoot the guard above you through the grate. Exit the vent shaft and look for a [WOODEN BOX].
  7. 7
    Drop down the ladder at the end of the walkway. Loot the [WOODEN BOX] here.
  8. 8
    Use the grapple hook to reach the next walkway. Peek around the corner and stealthily take out the guard with a melee attack from behind.
  9. 9
    Take cover against the wall near the corner, wait for the second guard to turn around, and take him out.
  10. 10
    Move up the small steps. Push the crate with canisters to reveal a vent shaft. Move through it to get past three guards.
  11. 11
    Take cover behind the boxes and proceed when the closest guard turns around.
  12. 12
    Duck at the 'window' opening and shoot the guard inside the room with a regular arrow when he's looking away. Break the [WOODEN BOX] and hop inside.
  13. 13
    Find another [WOODEN BOX] in the corner, being careful not to be spotted by the guard in the walkway.
  14. 14
    To stealthily kill the next guard, stand near the wall and position the camera to see him. When he approaches, head into the walkway and perform a melee attack, then hop through the window. If the second guard notices, quickly take him out or take him out from behind when he walks away.
  15. 15
    Continue on and note the upcoming Serpent Emblem.
  16. 16
    Move down the walkway and loot the [WOODEN BOX] at the very end before dropping down.
  17. 17
    At the end of the vent shaft, you'll reach a room with a puzzle. Inspect the locked door.
  18. 18
    In the adjacent room, press the button on the pedestal to move the animal's horns. View through the hole to reveal a sketch (snake, fish, bird, or human) behind the painting. Memorize it.
  19. 19
    Use the four devices in the room to match their sides with the sketch.
  20. 20
    Head through the door and a cutscene will introduce turret cameras.
  21. 21
    Go around the corner, take cover, and shoot the guard ahead with your bow. Stepping on the circular plate activates the camera, but it can be bypassed.
  22. 22
    Enter the room and find a [RED HERB] and [INCENDIARY GRENADES x2] next to the beamer, and a [GREEN HERB] on the desk.
  23. 23
    After the film, waste the three guards, head through the hall, turn right, and waste three more. Find [WOODEN CRATES x2].
  24. 24
    Climb the boxes and move through the vent shaft. Drop down and activate the two cameras by walking over the floor buttons. Look for [WOODEN CRATES x3] and [9MM AMMO].
  25. 25
    Find [WOODEN CRATES x2] around the corner. Quickly take cover from the guard behind a turret. Rush to the boxes ahead and activate the camera behind him.
  26. 26
    Go through two doors to reach a generator room. Find a [WOODEN BOX].
  27. 27
    Find another [WOODEN BOX] before dropping down.
  28. 28
    In the next room, collect the [ASSAULT SHOTGUN] from the workbench and continue down the walkway. Find a [WOODEN CRATE] guarded by a crab guard. Deal with the two guards ahead.
  29. 29
    Climb the ladder to reach a bigger area. Shoot the red canister to your left as you go around the corner (let the guard mutate first) to waste the J'avo. Find [WOODEN CRATES x3] and kill the J'avo.
