Switch off psi-radiation

After getting into X-16, you have to switch off the psi-radiation generator located here.
== Walkthrough ==
The entrance to the elevator shaft is covered by a wooden palette. It's a physical object, you can drag it away with Shift+F like any other object. (see also the #Bugs section).
After entering the brain chamber, a timer will start. You have 4 minutes to switch off the brain before your psi-helmet stops functioning and you die. Shutting it down involves triggering 3 switches on different catwalk levels, and the primary switch in the control room at the top. The enemies are also two pyro-controllers which are hard to see in the dark, and one grandmother controller which looks like a zombie; they are all located on the second level.
Switch the brain off, and watch the next Marked One's vision as he loses consciousness. Three new tasks will be started, based on things you've seen:
* Deja Vu - repeat the photo of Chernobyl NPP from the vision;
* Strelok's artefacts - find the artifacts you've seen in the vision
* Take the documents - a small transitional task to remind you to take the documents in the next chamber.
And also the next quest in the chain, Get out of laboratory.
== Notes ==
* Near the console with the primary switch you can find Ghost's PDA, to give it to Sakharov later. Make sure you fully listened to the audio note in it.
== Bugs ==
* The palette covering the elevator shaft ladder can't be moved sometimes. Try taking off your armor to fix that. (X-ray physics is quirky...)
* If you're still unable to move it, go to the options and find Options -> Game -> Delete problem objects, enter x16_physic_object_0004 here and press Apply.
* A wall in the [ utility room] is bugged, all controllers in the brain room can see and attack you through it.
* You will probably softlock your game by entering the lab if you haven't finished Find the Hiding of Strelok's group yet. This is a legacy bug from Shadow of Chernobyl.
* If you don't listen for Ghost's audio message in full and switch locations in the middle, Guide might not spawn. This is a legacy bug from Shadow of Chernobyl.
