The Underpass Fault in Control Resonant: Walkthrough From the Sinkhole Door

Finish The Subway Fault first, then descend the Sinkhole, guide the light-projected children, and complete Jesse's ritual.

Finish The Subway Fault first, then descend the Sinkhole, guide the light-projected children, and complete Jesse’s ritual.

Jesse’s Fault questline in Control Resonant ends with The Underpass Fault, which catches Dylan Faden amid the chaotic “Recursions and Iterations” section. Although its objective appears near the start, completion remains unavailable until you clear a different Fault. After that, the quest takes you on an extended platforming drop from the Sinkhole to the island of orange pipes, followed by a memory puzzle inside the Fault.

Quick answer: Complete The Subway Fault in the Evacuation Zone first. Then descend the Sinkhole, cross to the orange-pipe island, drop into its interior, enter the Fault, and seal it with Jesse at the easel.


Complete The Subway Fault first (the block you can’t skip)

While Dylan follows the research team through the Underpass, a vision of Jesse appears in the distance and the log updates to “Investigate the Vision of Jesse on the island of Orange Pipes.” There is no point chasing it yet. Zoe warns that Dylan can’t make the jump, because Faults must be finished in a set order and the Underpass one sits at the end.

The missing piece is The Subway Fault, which awards Reach, the ability that handles gravity anomalies. Without it you cannot complete the Underpass puzzle, and the main story mission “The House in Distress” stays locked. If you approach the pipe island without having done it, The Subway Fault starts automatically when you next return to the Evacuation Zone.

Open the map at a Fast Travel Door and select Main Street in the Evacuation Zone. Dylan arrives in Evacuation Zone 5, and the quest becomes available at once.
Glide down to street level, weave through the buildings, and make your way to the subway steps. Break the turnstile to enter the tunnels; take cover in side alcoves and stairwells whenever spectral trains roll past.
Drop into the mold-coated cavern beneath the tracks, then defeat the Bloomed Spore Mother and the Mold Blights. Beyond them, dash through the massive shaft with subway cars hanging along its walls, and take out the flying enemies at the bottom.
Run up the ramp into the golden portal, speak to Jesse, and take the Reach ability. Flip both television anomalies to reorient gravity, cross the floating islands, and finish the ritual at the cosmic aperture to complete The Subway Fault.

Route from the Sinkhole Door to the Fault

With Reach in hand, you can travel on foot from the Sinkhole down to the pipe island. The path runs through lit maintenance corridors, across a shifting chasm, up a field of pillars, and finally into the mold-infested tunnels where the Fault waits. You need both Shift (for walking on walls) and Reach (for gravity anomalies) along the way.

If you would rather skip the long walk, fast travel to The Spire near the research team’s base camp and glide across the hovering pillars toward the orange conduits instead.

Begin at the Sinkhole Fast Travel Door at the bottom of the Sinkhole. Head toward the green-lit doorway to start the route into the facility below.

Land on the pipe island, clear the Mold on top, then walk the edge until you find a ledge and drop onto it. Activate the “Fault” fast travel spot near Tubes Island here so you never repeat the trip if you die.
Head into the interior tunnels, grab the resource chest on the way down, and fight through the explosive Mold Hosts, heavies, and a fungal brute in the green-lit lower chambers. Grab the respawn point beside the small entrance before the fight.
Follow the square corridor toward the bright light at its depths as Jesse speaks over the radio. Reach the small dais ringed by curved pipes, then interact with the waiting TV to enter the Fault.

Inside the Fault: memory interactions in order

The Fault begins in a shadowy clearing beneath golden autumn leaves, and the objective reads “Find Jesse and Talk to Her.” Combat is absent here, unlike in the earlier Faults; progression depends on interacting with points in the environment. Look for white eye symbols on the stone faces and touch each memory in order to advance the quest. At first, simply walk straight across the floating slabs covered in leaves.

Memory promptWhat the projection shows
I remember MomDylan’s mother teaching him to paint
I remember DadHis father taking him camping and hiking
We were happyThe whole family together
Everything was simple back thenThe children playing Severed Circle 2
They didn’t recognize us anymoreThe parents’ shadows towering over Dylan
(Family breakdown)The father’s drinking and anger, the mother withdrawing
RememberBoth children reunited at the Christmas tree

Once you pass the third stone face, a golden human shape appears and goes through an opening in the monolith. Chase it across the floating slabs until you reach the wall showing the two children together; the puzzle begins there.


How to guide the light-projected children

Once the objective reads “Guide the Light-Projected Children,” remember that the silhouettes travel only across level ground. Your route over the nearby ledges pulls them along. A yellow glow surrounds Dylan’s head while they follow; if it disappears, backtrack until they catch up. Leaping around an unseen corner severs the connection.

Head left and step onto the platform with a slight tilt.
Continue along the route, leaping between platforms until you arrive at the pair of large parent shadows.
Interact with the wall when prompted. The projection then plays out the family’s collapse.

Reunite young Dylan and Jesse

This is the Fault’s hardest room. Young Dylan starts following you automatically, and you need both figures standing at the same wall at the same time. Reach and Shift are both required here.

Pass through the large rectangular shadow as it forms on the wall, then circle around until a passage becomes available on your right.
Use the route on the right rather than attempting to leap across the gap. Follow it to the ledge above the lowest area, then jump to the raised platform immediately ahead and proceed toward the wall shadows.
Search high on the wall to your left for light-projected Jesse. Take the left route, jump onto the ledge, and cross the gap with Reach.
Continue down, jumping across to the platforms on your right, until you reach the smaller young Jesse. Lead her to the highest point on the platform where you first found her.
Leap back to the platforms across from you; the projection remains behind. Climb to the next elevated platform on your right, then float across and use Shift on the platform opposite, targeting the area blanketed in golden leaves.
Circle along the platform until you are above the spot where you left the projection. It should hop up to you without help. Go back the way you came, activate Shift once more, and move on.
If a rocky outcrop comes into view on your right, climb onto it to keep the projection from getting stuck. Jump from platform to platform on your way back to the wall, then interact with it. The children meet before a Christmas tree projection, triggering the “Remember” memory.

When the cutscene ends, fall through the floor opening and walk ahead until Jesse is within speaking distance.


Help Jesse complete the ritual

The final stretch is linear. Walk the wooded path to find adult Jesse standing under a street lamp and speak with her. Replies such as “You were just a kid too” are dialogue flavor and do not gate anything.

The objective becomes “Help Jesse Complete the Ritual.” A projection shows the night their mother aimed a rifle at them. Follow the glowing, leaf-strewn highway toward the eclipse-like rift, and beyond it you’ll find an easel with floating artwork beside a lit CRT television. Jesse explains that they are astrally projecting, that she must seal the Fault from her side, and that she is preparing for one final Fault.

Finish every dialogue prompt before leaving. If The Underpass Fault still appears as tracked in your Quest Log, the ritual conversation is incomplete. Go back to the easel and finish any dialogue left before proceeding.


Rewards and how to confirm the quest is finished

Success is signaled when Jesse fades away and Dylan wakes in the real world in a space filled with relics from his childhood bedroom. The banner displays “QUEST COMPLETED: THE UNDERPASS FAULT,” while both reward notifications appear at once.

Once the quest closes, use The Spire fast travel point to head back into the Underpass, then return to the beacon location to resume “Recursions and Iterations.” The Halfway Trail door in the middle of the Underpass map is the closest jump if you want to pick that mission back up quickly.
