Walkthrough
  1. 1
    Exit the vent and save your game. Enter the control room. Wait for the guards to finish their conversation, then take out the one leaning against devices.
  2. 2
    Observe the window to spot a patrolling guard on the bridge. Avoid being seen by him. Hide the bodies of the taken-down guards in the vent or near the wall to prevent the other guard from spotting them.
  3. 3
    Locate an Ebook (The Sleepwalking World) next to a LVL2 PC. Use it to shut down nearby cameras. The login is POOLRM/pelagic.
  4. 4
    Find a [CYBERBOOST PROENERGY PACK] on the computer panels, [50 CREDITS] and [2x 10MM PISTOL AMMO] in a drawer, and two [COMBAT RIFLES] in the weapon cabinet.
  5. 5
    Proceed through the double doors and head upstairs. Take down the guard around the left corner when he is not facing you.
  6. 6
    Use the LVL3 security panel (7934) to access a maintenance generator room. Inside, find [7x MACHINE PISTOL AMMO], [325 CREDITS], and [3x TRANQUILIZER DARTS] in two lockers.
  7. 7
    The other generator room is empty. The small area secured with a LVL2 system contains [5x 10MM PISTOL AMMO] and [10x MACHINE PISTOL AMMO].
  8. 8
    Head through the door and ride the elevator up to the TYM ASSEMBLY area.
  9. 9
    In the hall, move the two small metal crates to reveal a [STOP! WORM SOFTWARE].
  10. 10
    Find a [POCKET SECRETARY] on a box. The locked LVL4 area contains a [CYBERBOOST PROENERGY BAR], [STUN GUN DART], [P.E.P.S. ENERGY PACK], [P.E.P.S.], and a breaker box to shut down electric current.
  11. 11
    Alternatively, to bypass the LVL4 hack: continue into the next room, avoid water, enter the ventilation shaft behind the red box [EXPLORER 100XP]. Collect [15 + 25 CREDITS] inside. Enter the area with the breaker box this way.
  12. 12
    The other storage room contains [10x SHOTGUN CARTRIDGES], [35 CREDITS], and [4x MACHINE PISTOL AMMO].
  13. 13
    In the next room, use the red box to hop over large containers to access a secret area [PATHFINDER 300XP]. This area contains [55 CREDITS], a [CONCUSSION GRENADE], and [4x MACHINE PISTOL AMMO].
  14. 14
    Use metal crates to climb the structure and reach the high catwalk. Find [2x MACHINE PISTOL AMMO] in the center by moving a metal crate to reveal a small wooden box.
  15. 15
    In the next room, locate a vent (use a large metal crate to reach it, or Jump Enhancement). This vent leads to a long shaft. Jump down only if you have the Icarus Landing System.
  16. 16
    This grants the [TRAILBLAZER 400XP] reward and items: an [ACCESS CARD] and a [POCKET SECRETARY] from a body, a [HUGH DARROW EBOOK] (Better Than Nature?), a [TRANQUILIZER RIFLE], and a [RELOAD SPEED UPGRADE].
  17. 17
    If you don't have the Icarus Landing System, consider getting it. The vent leads back to the breaker box room. Return to the previous room.
  18. 18
    The room blocked by a large metal crate contains [2x TRANQUILIZER DARTS] and [1x STUN GUN DART].
  19. 19
    Ride the elevator up to the next area, receiving [1750XP] + [GHOST 500XP] + [SMOOTH OPERATOR 250XP].
  20. 20
    Enter TAI YONG MEDICAL FIRST FLOOR. Keep your weapon concealed and head down the hall.
  21. 21
    Explore the first room to your left. It contains [50 CREDITS] in a drawer, [PAINKILLERS], and an unlocked PC. Move large wooden crates to find [3x TYPHOON AMMO], a [CYBERBOOST PROENERGY PACK], [5x CROSSBOW ARROWS], and [2x WHISKEY].
  22. 22
    Find a hidden [NUKE VIRUS SOFTWARE] on a high cabinet.
  23. 23
    Avoid hacking the LVL3 panel in the security room opposite when a guard is present. Instead, find a ventilation shaft (hidden by two small metal crates) at the top of crates in an open storage room. Stay crouched and hidden.
  24. 24
    Inside the vent, find [10x MACHINE PISTOL AMMO], [8x COMBAT RIFLE AMMO], [4x TRANQUILIZER DARTS], and an [ACCESS CARD]. Exit through the vent.
  25. 25
    Take down the guard when he passes the storage room and drag him inside. He carries a [POCKET SECRETARY] with the lab keycode (4713).
  26. 26
    Nearby rooms have unlocked PCs with background info. Use the vent here to reach the next area if playing differently.
  27. 27
    Alternatively, carry the vending machine (with Strength Enhancement), hop onto it (with Jump Enhancement), and place it under the balcony to reach the second floor instantly.
  28. 28
    Enter the Lee Geng Memorial Laboratory. Find a [HUGH DARROW EBOOK] (Radical Evolution is a Reality) on a box under the central lab unit.
  29. 29
    Find a [POCKET SECRETARY] with a PC login on another desk. Unlocked PCs contain background info.
  30. 30
    Locate a LVL2 PC in one of the rooms.
