Reach unlocks by completing Jesse Sightings: The Subway Fault. It activates grapple-style traversal points and is a required progression tool for Underpass routes and later exploration.
Which quest unlocks Reach?
Open the Search for Jesse track and complete Jesse Sightings: The Subway Fault. Recursions and Iterations can direct you into this quest if the campaign reaches the dependency first.
Finish the Fault before returning to deep Underpass exploration. Seeing an anchor early does not mean the save already owns the ability needed to use it.
What Reach does
Reach lets Dylan connect to grapple points across gaps and altered spaces. It covers movement that a normal jump cannot clear and that Shift cannot solve by changing surface orientation.
Frame the anchor in the camera, wait for the usable state, then activate Reach. Continue steering after the pull because some routes expect a chain rather than a single automatic landing.
Why Reach matters in Underpass
The campaign checks The Subway Fault during Recursions and Iterations, and Reach supports the routes that move Dylan deeper into Underpass. It also reduces wasted searches around gaps that intentionally have no bridge.
A visible anchor is stronger evidence than a nearby staircase. When the environment presents repeated grapple points, complete the Fault instead of trying to bypass the route.
Reach and Shift solve different problems
Shift changes how Dylan travels across gravity surfaces. Reach pulls him toward designated anchors. Many late routes combine the two, but neither is a direct replacement for the other.
If the prompt is absent, identify the environmental cue first. A folded wall suggests Shift; a distant anchor suggests Reach; a sealed panel requires an impact or fire solution.
If a Reach point will not activate
Verify The Subway Fault is complete and move until the anchor is unobstructed. Check whether the current objective must advance before that specific route becomes active.
Leave and reload only after confirming the progression state. A checkpoint refresh can repair a stale prompt, but it cannot grant Reach before the Fault is finished.
How this guide was checked
CONTROL Resonant: Unlock Reach was independently summarized from current launch-week quest, boss, and progression references. The page separates confirmed dependencies from route advice and avoids treating one build choice as universally correct.
