It's easy enough to get lost when floating specter-like monstrosities try to drive you crazy. Check out the step-by-step tutorials with screenshots below to make these two puzzles much more sensible. The lab puzzle is also completely optional - after restoring power to the facility, you are free to leave without completing the extraction procedure.

How to solve the theater puzzle:
Collect a second Power Node in the dark room of the theater - crouch down in the left hallway at the back.
Use the center room power node and the theater power node to connect the power to the room on the left in the main hall.
Collect the third power node and use all three to connect power to the main theater itself.
Solve the theater hall puzzle: With the power on, pull the lever near the ladder on the right side of the stage. This will cause a cage to arrive with a body inside on a rail.
- Pull the floor switch near the screen in the center of the room to remove the body.
- Pull the delivery switch again - this time, climb up to the high ledge and enter the cage before it closes. Drive it and let the machine scan you.
- Press the button on the scanner once it starts flashing red.
After a visit from an NPC, use the floor lever again and enter the cage before it closes.
How to extract the Vitae | Laboratory puzzle:
Once you reach the room with the Healing Chair, continue deeper into the facility. In a large dark storage room, find the desk and bring the Power Node back with you.
- On the way back, a monster will appear - quickly return to the operating room with the node.
Along the way, in the great room with a view of the expedition devices, plug in the power supply to the console near the windows. Flip the switch, then take the Power Node and connect the power supply to the operating room.
Now that the power is back on, a man in a cage will appear. There are three steps to follow to generate vitae.
- Starting the Vitae extraction machine:
- Attach the pointed knives to the ends of the four main arms of the torture device.
- Find the small multi-pin connector tab and insert it into the console. Look for the one with a horned "Y" symbol on the front.
- When you are ready, press the button on the torture device, then lift the lever on the main console. Hold it until the shutter closes.
Continue to hold the lever until all of the blue lights are filled on the console. You can now collect the filled Leyden Jar and insert it to use the device.
