Chamber 9: Silent Running

Step 1: You start above a robot. Wait until it moves to the left wall, then drop down. Immediately jump up to the platform with the vertical sliders. Carefully run across the sliders, but make sure to step on the far-right one. This will send it back up, resetting it with the others.

Step 2: Head to the middle of the room, onto the single sound tile. From here, you need to jump *over* the far-right sound tile and land in the corner near the switch. Step into the sensor beam for a second, then back out. This lowers the slider onto the switch. If you're aiming for that hidden [Helix], this is your chance to grab it.

Step 3: Now, wait for the walking robot to step into the slider's sensor. As soon as it does, make a break for the terminal. The slider will take care of the robot, making hacking much easier. After hacking, step in and out of the sensor beam again to reset the slider, then climb the sound tiles to the top of the room.

Step 4: Hack the panel at the top. Carefully drop down the step on the left. This is a tricky part: you need to quickly jump to a small, hard-to-see square block opposite the Red Drone, and then immediately jump back to the step. If you're fast enough, you won't accidentally bring the slider back up.

Step 5: Drop to the lower floor and run right. Approach the terminal only after the robot has been crushed by the vertical slider. Activate the panel, then run to the next terminal. Finally, climb the sound tiles to reach the exit.
