Navigate the Tai Yong Medical Fourth Floor and Penthouse in deus ex human revolution. Find P.E.P.S. ENERGY PACKs, credits, and learn stealth tactics.

Walkthrough
  1. 1
    On the Tai Yong Medicat Fourth Floor, search the first room for an Ebook (A Frontier Too Far?). Navigate the hall with laser beams.
  2. 2
    In the office ahead, find a [P.E.P.S. ENERGY PACK], [50 CREDITS], and [15 CREDITS] in the desk drawers. Collect [4x SHOTGUN SHELLS] from a cart, being mindful of two guards in the hall.
  3. 3
    In a nearby small room (LVL3), access a LVL2 PC to shut down the camera and potentially a robot. Find a [POCKET SECRETARY] and [1x STUN GUN DART] in the drawers.
  4. 4
    To neutralize the guards, wait for them to move away and hide behind the desks on the far right of the office. Take out the regular guard when the grunt is moving away, then hide his body. Wait for the grunt to move out of the camera’s sight to take him out. Loot the EMP Grenade from the grunt.
  5. 5
    Explore the area further. Desk drawers contain: [POCKET SECRETARY], [25 CREDITS], [15 CREDITS], and [65 CREDITS]. Two PCs offer background information. A desk near the camera holds a [POCKET SECRETARY] with login details. Other desks contain [45 CREDITS] and a [STUN GUN DART].
  6. 6
    Proceed through the door and down the hall. A small room to your right has a vent (after moving a large metal crate) connecting to the opposite room.
  7. 7
    Inside this room, you can perform a double or single takedown on the two guards. Desk drawers yield [10x MACHINE PISTOL AMMO], [35 CREDITS]. Lockers contain [11x MACHINE PISTOL AMMO], a [P.E.P.S.], and [3x P.E.P.S. ENERGY PACK]. The weapon cabinet holds two [MACHINE PISTOLS] and a [GAS GRENADE]. Hack the LVL3 PC for an access code.
  8. 8
    Continue down the main hall and open the door at the far end of the left hall by standing next to it. The guard (Narhari Kahn) will investigate. Perform a takedown and collect his [500 CREDITS]. His office desk drawer contains [2x SHOTGUN SHELLS] and [2x REVOLVER AMMO]. The LVL 4 PC contains background information (password: ironfist).
  9. 9
    Another room is locked with a LVL 4 security system (code: 3090). The PC inside has an email conversation.
  10. 10
    Down the hall, find [4x MACHINE PISTOL AMMO]. Approach the next room cautiously, as it's monitored by a camera. Position yourself underneath it, then hop over the desk to read the PC’s email. The drawer contains [80 CREDITS].
  11. 11
    Accessing the LVL 1 door with the keycode (6906) is difficult with the camera active. It's easier to use the other door, enter the small room (containing [5x SHOTGUN SHELLS]), and break the wall (using an augmentation or weapons).
  12. 12
    Enter the Tai Yong Medical Penthouse. Look underneath the second left bench for a [POCKET SECRETARY] with a keycode (0117) for Zhao Yun Ru’s safe.
  13. 13
    The desk contains [3x STUN GUN DARTS], [2x TRANQUILIZER DARTS], and a [HYPOSTIM]. Note the vent on the upper left side of the hall, which connects to the area upstairs.
  14. 14
    Find a [REVOLVER] under the left bench, a [CYBERBOOST PROENERGY BAR] on the right table, and a [MINE TEMPLATE] under some boxes near the benches. The desk contains [3x REVOLVER AMMO], and the PC has interesting information.
  15. 15
    The LVL 5 safe (0117) contains [850 CREDITS], a [POCKET SECRETARY] (with a message from Bob Page), and a [HEAT TARGETTING SYSTEM]. A cutscene (a non-interactive cinematic the game plays automatically) plays awarding [750XP], [GHOST 500XP], [SMOOTH OPERATOR 250XP].
  16. 16
    For a stealthy exit, wait for guards to patrol or quickly move to the vent on the right side. Enter the ventilation shaft (on the right side of the stairs as you go down one level) and sneak past the nine guards downstairs.
  17. 17
    Alternatively, toss two gas grenades to cover (press the cover button to crouch behind walls or objects) the left/middle and right/middle areas to eliminate the guards efficiently. One guard may carry a Gas Grenade. Warning: If aiming for the “GHOST” trophy, activate cloak when throwing gas grenades.
  18. 18
    Ride the elevator at the far end of the penthouse up [2500XP], [GHOST 500XP], [SMOOTH OPERATOR 250XP].
  19. 19
    As you enter the hangar, two Box Guards activate. To disable them without alerting others, move to the far left and shoot the camera with a silenced weapon.
  20. 20
    When a Box Guard moves away, toss an EMP Grenade at it. Use cloak or extreme caution to avoid detection by the other bot. Run towards the end of the hangar where the camera was. Jump on the large iron shelving.
Tips
  • A grenade thrown into the middle of the guards downstairs can quickly eliminate them.
  • If you have the cloak augmentation, it is highly recommended for stealthy actions, especially when dealing with the Box Guards.
  • Destroying the camera in the hangar with a silenced weapon before engaging the Box Guards is crucial for stealth.
