Chamber 8: Field Work

Hit the Red Button to reveal the room. Press the switch to create a hard light platform, run across as a shadow passes, activate the panel, and jump into the pit when a shadow passes overhead.

Hit the switch again. Follow the shadow by jumping up, hitting the switch, hanging off the next platform, pulling yourself up, and jumping into the pit below the first security camera.

As the next shadow comes, jump up and hop to the terminal on your right. Begin hacking it (this uses one of your four 'allowed' spots for the S-Rank). Drop into the pit below the camera above you and do the same for the next pit when the next shadow passes overhead.

Wait for another shadow before jumping out and immediately jumping up to the ledges above. From here, quickly leap to the platform above and crouch-walk in time with a passing shadow.

Leap up in the shadow to the sensor beam on the left, then leap right when a shadow passes. The next shadow won't be large enough to cover the whole hard light floor, so quickly move out just as it gets close.

Repeat shadow-timed jumps until you reach the top terminal. Run past the terminal when a shadow passes, then run left and hack the terminal as the next shadow reaches you. You will likely be spotted by the Boss.

Drop down the left side in the shadows, then drop to the next switch below as a shadow is cast over the light. Hit it, then jump over the green hard light when a shadow passes. Crouch walk left; stand up in the shadow and quickly ledge jump up to the switch above as the shadow descends.

Use a shadow to mask your drop to the ground and run left to the wall ledges. Wait for the boss to look away before jumping up and hacking the terminal. You'll likely be spotted again. Drop down and duck back into the shadows.

Wait for a shadow to come down and ledge leap up the hard light, then jump to the two wall ledges near the boss. Wait until it looks away. If you still need the [Helix], grab it now. Otherwise, time your drop down to the exit with a shadow to escape.
