The article explains how to complete the lens puzzles at the end of Chapter 3, “Those Before Us”, in *Resonance: A Plague Tale Legacy*. Players must redirect beams of light through movable lenses to open a sealed door, reveal three minotaur paintings and activate an elevator, making it an early example of the game’s trial-based puzzle design.

The first puzzle is a tutorial: rotate the two lenses beside the door so each beam reaches its nearby golden disc. In the next room, activate the central gilded pillar, direct the right-hand lens to the far golden disc, then link the opposite lens to it and redirect the first beam through a third lens to another disc; finally, have Leni hold up the broken lens and aim the lens opposite the doorway at it to reveal the last painting and use the lift.
