Chamber 3: Hide And Seeker

Drop down, dash to the panel, hack it, then ledge leap up to the terminal above. Stand on the left side of the terminal to trick the Seeker into missing its shot, allowing you to hack the next terminal without being spotted.

As the Seeker fires, drop down, rush right, hop up to the terminal, and then hop over to the Helix if you still need it. Drop down, run right, hop up to the next terminal, hack it, run into the next room, and scale the ledges to the panel at the top. Once the lights are off, drop down and head right into the next room.

Leap up to the second green platform and stand there until the Seeker reaches the hard light at the entrance to the room. This triggers the clone below to hack the terminal. Jump to the top platform and hide in the shadows until the clone finishes hacking. Drop down, hit the switch, and ride the lift down to the long corridor.

Distract the Patroller by jumping on the sound tiles, then run by the closed door in the shadows. Crouch walk towards the terminal when the door opens. If the Patroller moves upwards, do not make a sound and wait for it to return to its starting position before hacking the terminal.

Run to the next pair of sound tiles and jump on them to distract the Patroller. Stay in the dark until it faces away from you. Be careful if it starts moving right, and crouch-walk away. Run to the closed double doors for the final stretch.

Stand in the sensor beam to open the door for the clone above. Race left and wait until the clone is killed before leaping up to the exit.
