I explained the solution to the Laser laboratory puzzle in the game with a simple method in this guide.
Laser Lab
The Steps:
- Make it into the laser lab
- Get the laser deflector idea from the whiteboard in the laser lab
- Make 2 laser deflectors
- Get a medium and large filing cabinet
- Position the laser reflectors and cabinets like in the picture below
After hearing a glass shattering noise and seeing the small portal disappear, go to the dark lense to find that a new portal is open for you to enter (don’t go in unless you’re prepared for a big fight).
