Part 55 walkthrough for Once Human: Find William Taggart and David Sarif, and prepare for the final boss battle against The Hyron Project.

Walkthrough
  1. 1
    From the far right, quickly hop through the broken window to make it to safety.
  2. 2
    The next hall leads to the last LIMB Clinic (a place to buy items and upgrades). If you can spare the credits, buy the two last Praxis Kits (items that grant augmentation points), along with Hypostims (healing items) and Typhoon Ammo (special ammunition).
  3. 3
    Continue through the hall. William Taggart will ask for help.
  4. 4
    Go through the doorway and hop onto the black beams, then look to your right and jump onto the blue scaffolding.
  5. 5
    Move towards the building's wall and hop onto the edge, then crawl to the far side of the area and drop down.
  6. 6
    Go through the doorway by moving over the beams. Head through the hall, but beware when going down the stairs; there are cameras (surveillance devices) up ahead.
  7. 7
    As the camera looks away, turn left and drop down next to the pipes, hugging the wall to stay out of sight.
  8. 8
    Moving to the end of the pipes leads you to a vent cover (press the cover button to crouch behind walls or objects); head inside and go straight ahead, ignoring the shaft to your right for now.
  9. 9
    This leads to William Taggart's room. Speak to him twice to get all the main dialogue, then exit the room.
  10. 10
    Loot the corpses, go around the corner, and move the metal crates away from the wall to reveal a ventilation cover. Head inside and you'll find yourself back at the pipeline area.
  11. 11
    Backtrack the way you came, avoiding the cameras stealthily.
  12. 12
    Crouch and move to the railing south of you. You'll need the Icarus Landing System (a traversal tool) along with cloak (an invisibility ability) for the next maneuver.
  13. 13
    While crouching, head west and approach the scaffolding. Turn on cloak and hop down the railing to your right; you should fall down the long, big ventilation shaft.
  14. 14
    There are crazies (hostile enemies) down below, so immediately go through the double doors and shut them behind you, then go around the corner and turn off cloak.
  15. 15
    At this point, Sarif contacts you; he's in need of help. Go through the door, crouch, and hop over the pipes.
  16. 16
    Move through the area while hugging the left wall. The same principle applies to the next room downstairs.
  17. 17
    Hop onto the box in the upper right corner and enter the vent, which leads straight to Sarif.
  18. 18
    Speak to him twice and be on your way (500XP). You can find [10x PLASMA CAPSULES] in the locker, just like a [LASER RIFLE BATTERY].
  19. 19
    Head back through the vent and turn right; switch on cloak and go straight for the other doorway.
  20. 20
    Don't continue down the hall; it's rigged with mines (explosive traps). Instead, head through the LVL 4 door on your left.
  21. 21
    Beware, there are two more fragmentation mines in this hall, so slowly approach them to deactivate these.
  22. 22
    Entering the door grants you [PATHFINDER 300XP], but you will go upstairs instead.
  23. 23
    Crouch through the hall and approach the doorway at the end. Immediately turn right to crawl underneath some devices.
  24. 24
    Use cloak to move towards the next hiding spot, while you keep hugging the right wall.
  25. 25
    From here, use cloak once more to move onward; proceed around the big device, through the door, into the hall to the northeast. Close the door to ensure safety.
  26. 26
    Head down the empty hall and call the elevator (a lift for vertical travel), which is a fairly long wait, then ride it up.
  27. 27
    Move down the hall to your right and continue until you reach some closed doors. This is a fairly tough part to get past stealthily, unless you have several energy cells and bars (items that restore energy) so you can use cloak for a decent amount of time.
  28. 28
    Otherwise, drop to the sides of the railing to replenish your energy and take short spurts until you reach the other side. Make sure you don't touch any of the crazies or they'll go crazy!
  29. 29
    The elevator leads to the final area of the game, where the final boss battle starts. Loot the bodies in the final hallway and grab the Plasma Rifle if you don't already have one, then go through the doors.

FINAL BOSS BATTLE: THE HYRON PROJECT

The Hyron Project is partially controlled by Zhao Yun Ru, but also appears to have a will of its own. It is armed with powerful machine gun turrets that circle around it, shooting at you whenever possible. To destroy it you'll need to destroy Zhao, but she's protected by a shield that you need to destroy first.

There are three pods with Hyron Drones inside the central structure that you must destroy in order to lower Zhao's shield. You can either press the buttons next to the pods in order to open them, revealing the drones. Go over each and kill them one at a time. After destroying two drones, crazies will be released inside the room that you'll probably want defeat by using takedowns (stealthy melee attacks), so having a few energy bars left will come in handy. When you've destroyed all three drones, medium security bots are released. These can be destroyed with Typhoon rounds or EMP Grenades (items that disable electronics).

An alternative way for killing the drones is to hack the LV4 PC's (computers) in the perimeter. You are only briefly shielded from the turret gunfire by the breakable glass, so you should consider using cloak. You'll still need to kill the Hyron Drones after opening their pods, but you can now do this from a distance.

Yet another way to deal with the Hyron Drones is to simply head for

Tips
  • Buy the last two Praxis Kits, Hypostims, and Typhoon Ammo at the last LIMB Clinic if you have the credits.
  • Use cloak and the Icarus Landing System to navigate the ventilation shaft stealthily.
  • Conserve energy for cloak and takedowns during the final boss fight.
  • Consider hacking LV4 PCs to deal with the Hyron Drones from a distance.
