To reach the chamber entrance in Control Resonant, enter the laundromat in the Evacuation Zone, take the stairs behind it, and follow the interior corridors until they open into a large vertical chamber. The route continues from the chamber floor through stone corridors and down a concrete stairwell, ending at the walkway that marks the Underpass.
Start at the Evacuation Zone laundromat
This route is described during the main-story quest “Recursions and Iterations,” when the active objective is “Find the Team Below the Sinkhole.” Pass the laundromat sign and go inside. The entrance is not the laundromat itself: take the stairs behind it to continue below ground.
