Control Resonant: The Underpass Fault Walkthrough (Island of Orange Pipes)

Following a faint vision of Jesse leads Dylan Faden to the point in the Underpass where the patterned orange pipes converge. The objective sits in Underpass 3 and begins as “Investigate the Vision of Jesse on the island of Orange Pipes,” part of the Search for Jesse chain and the mission “The Underpass Fault.” Reaching the Fault means platforming to the island, dropping through a mold-choked chamber, and jumping onto a glowing platform suspended over a void.

Quick answer: Finish the Subway Fault to unlock Reach, travel to The Spire, cross to the orange-pipe island, clear the mold chamber, then jump onto the glowing platform to enter the Fault.

What you need before The Underpass Fault

This objective appears during Recursions and Iterations, once the campaign sends you below the Sinkhole and you spot both a beacon and the island of orange pipes. Attempting the investigation right away triggers a soft-block, so the game expects you to step away and finish another Fault first.

The Reach ability, which pulls Dylan toward traversal points.
Reach is earned by completing the Subway Fault in the Evacuation Zone.
The Subway Fault itself requires Shift, unlocked earlier at the Incursion Fault.

When the “Investigate the vision of Jesse on the island of orange pipes” objective stalls, leave the Underpass, complete the Subway Fault, then return here to continue. The quest is designed to block progress until Reach is in your kit.

Reach the island of orange pipes from The Spire

Open a Fast Travel Door, choose the Underpass, and select The Spire. Arriving here saves a long trek and puts you on the correct side of the map for the pipe island.

On The Spire platform, open the Underpass map. The yellow quest area sits to the northwest, marking the cluster wrapped in orange pipes.

Glide and jump across the floating concrete pillars toward the structure wrapped in thick orange pipes. Use Reach on the traversal points to close the gaps over the drop.

Land on the pillar platform beside the pipes and activate the Fast Travel Door on the red circular emblem. This unlocks a permanent travel point at the Fault so you can return quickly later.

Clear the mold chamber inside the pipes

Scale the concrete blocks attached to the neighboring structure, then follow the orange pipes upward to an open, illuminated doorway near the top.

Descend through the interior shaft and land in the flooded chamber below, where green mold has spread.

Defeat the fungal Resonant enemies that attack in the water. Clearing them drops Source along with Thriving Spore and Fungal Growth.

Follow the corridor straight ahead. Jesse’s whispers play as you move through it, and The Board tells Dylan to enter alone. The objective then updates to Enter the Fault.

Enter the Fault

Leave the corridor and step onto the huge, bending orange pipes suspended above the dark void.

Follow the pipes downward, then leap onto the glowing square platform covered in flowers at the center. Touching down starts the Fault entry.

How to confirm the vision is complete

The investigation ends once Dylan appears in a dark, foggy forest clearing and Jesse speaks. Your tracker records that you pursued the vision to the island’s center and discovered a Fault; the objective then switches to Find Jesse and Talk to Her.

After that, the Underpass Fault continues, but awards no new traversal ability. Lead the children formed from projected light, bring young Dylan and Jesse back together, and finish the ritual. Then return to the Underpass using The Spire fast-travel point.

Completing this Fault closes out the Notes: Jesse Sightings tracker and clears the soft-block on Recursions and Iterations, letting the main story pick back up at the beacon location. Because a Resonant Cycle can strengthen returning enemies as you push deeper, it is worth spending Health and Power Upgrade Points before you move on.
