Hazards
Walkthrough
- Walk over to the Beams and place a portal on the wall on the left-side where the Beam ends.
- Place the other portal to the column facing the three Receptacles.
- Pick up the cube that is already redirecting one of the Beams. Place the cube in front of the portal, so the Beam activates the middle Receptacle.
- Pick up the other cube and place it over the beam coming from the ceiling. Aim it at the Receptacle on the right side.
- Go to the Chamberlock.
