The Talos Principle: Reawakened remastered the original game and its Road to Gehenna DLC in Unreal Engine 5, but it also added something completely new to the classic puzzle game.
A brand new expansion called In the Beginning, which added 18 new puzzles for players to solve, and was a narrative prequel to the original game. What makes In the Beginning particularly special, is that 16 out of the 18 puzzles included in the expansion were actually made in collaboration with members of the community who had been making their own levels for the last decade.
It's a special inclusion, that also solves the mystery of why the In the Beginning puzzles are some of the most difficult ones to solve across the entire Talos Principle series. They're puzzles for hardcore veterans, made by hardcore veterans.
This guide will show you how to solve the Parabolic Interference puzzle. If you only want a hint before getting the full solution, then what I'll say is you need to make two laser webs, not one big one.
For the full solution, read on.

- When you walk into the puzzle area, grab the hexahedron, which will release the pressure switch and change which gates are down and which are up. Place the hexahedron in front of the fan on the right side of the puzzle area.
- Grab a connector (C1) and connect it to the blue and red laser generators, as well as the blue and red nodes that control the shields that block the path to the tetromino, opposite the entrance to the puzzle area. Place it on top of the hexahedron.
- Grab the other connector (C2) and connect it to the red and blue laser generators, the blue and red nodes on either side of the puzzle area, the ones that will activate the fans, and lastly connect it to the same blue and red nodes C1 is connected to. Place it down on top of the pressure switch.
- Head over to the shields blocking the path to the tetromino. You'll be able to see the hexahedron and C1 on top of it fly back and forth in the air as the nodes on either side of the puzzle area activate between the red and blue lasers.
- The shields should now oscillate, letting you walk between them and step towards the tetromino to complete the puzzle.
