InThe Talos Principle 2, intricate puzzles meet deep philosophical themes. You find yourself transported into a world where the post-apocalyptic ruins of human culture are inhabited by a society of overly-cautious robots terrified of repeating the folly of humanity. To truly dive into this thought-provoking narrative, however, you’ll first need to complete the game’s tutorial by unlocking three sigil doors.

For this, you’ll not only need to solve a series of puzzles to obtain the sigils but also place them in the right sequence within the doors. If you find yourself endlessly rotating blocks to try and fit them into the sigil locks, don’t fret! This guide will guide you through every single sigil door.
