Can't reach the island of orange pipes?

Can't reach the island of orange pipes?

The gap is intentional. You need Reach to cross to the island.

Can you use Reach Points?

Why this quest appeared

A vision of Jesse interrupts your Underpass route.

You can see the island of orange pipes, but the gap between you and it is a Reach gate. Cross it, follow the Fault, and finish what Jesse started.

Verification pending

Some guides say the light-projection puzzle uses Shift. Whether Shift is a quest requirement, an inherited prerequisite, or only a puzzle dependency is still being verified, so it is not listed as required.

Quick answer

Cross to the island of orange pipes with Reach, clear the Mold enemies, and enter the pipe structure. Follow the interior route to the TV to enter the Fault. Find Jesse, guide the light-projected children, reunite young Dylan and Jesse, and finish the ritual. Then return to your Underpass route.

Step 1 of 7

Reach the Island of Orange Pipes

The Underpass Fault steps

Seven steps. Mark each one as you finish it and the page keeps your place.

Not startedYour progress

  1. Reach the Island of Orange Pipes

    Cross the gap with Reach and land on the pipe-covered island.

    Current

    Reach required before this step

    Route
    1. Start from your current Underpass route
    2. Use the Reach Points across the separated platforms
    3. Land on the island of orange pipes
    The island of orange pipes seen from the Underpass
    How are you getting there?

    Follow the storyline route from your current Underpass objective. The marker leads to the island.

    Landmark

    Orange pipes and separated floating platforms

    Watch out

    If the Reach Points give no prompt, you have not unlocked Reach yet. Stop and complete The Subway Fault.

  2. Find the Fault Entrance

    The Fault is inside the pipe structure, not on the exposed top of the island.

    Route
    1. Reach the main island and clear the Mold enemies
    2. Move around the side of the pipe structure
    3. Find the opening that leads inside
    The side opening into the pipe structure

    Marker here, but no Fault?

    The Fault entrance is not on the exposed top of the island. Find the opening into the pipe structure, then follow the interior route to the TV.

    Side opening into the island
    Landmark

    A side opening into the pipe structure

    Watch out

    If the objective marker points at the top of the island and nothing is there, look for the side entrance instead.

  3. Enter the Fault

    Follow the interior route to the end and interact with the TV.

    Route
    1. Follow the inside route through the pipe structure
    2. Find the TV at the end
    3. Interact to enter the Fault

    Interact → Fault transition

    Landmark

    The TV at the end of the interior route

    Watch out

    There is no Fault door icon. The TV is the interaction point.

  4. Find Jesse

    Follow the projected memories deeper into the Fault.

    Route
    1. Follow the projected memories
    2. Keep moving toward the objective marker
    3. Talk to Jesse when she appears
    The first projected memory inside the Fault

    Continue until the memory sequence opens the next route. This part is linear.

    Landmark

    Jesse along the Fault route, not at the entrance

    Watch out

    If you cannot find Jesse, you have probably not gone far enough into the Fault yet.

  5. Guide the Light-Projected Children

    Bring the projected children along the connected route to the target.

    Route
    1. Understand that the projection follows your movement
    2. Guide it along the connected platforms
    3. Bring it to the target marker

    Landmark

    The projected child and the target it must reach

    Watch out

    Do not try to skip straight to the target. The projection only moves along the route it can follow.

  6. Reunite Young Dylan and Jesse

    Bring the two projected children together.

    Route
    1. Follow the objective to the reunion point
    2. Guide the projection into position
    3. Let the reunion play out
    The reunion target
    Story details
    Landmark

    The reunion target for both projections

    Watch out

    If the reunion does not trigger, one projection is probably not in the right position yet.

  7. Complete Jesse's Ritual

    Help Jesse finish the ritual.

    Route
    1. Reach Jesse at the ritual site
    2. Interact to start the ritual sequence
    3. Finish the required dialogue and interaction
    Jesse at the ritual site
    Story details
    Landmark

    The ritual site deep inside the Fault

    Watch out

    The quest is only complete after the final ritual interaction. Do not leave early.

Guide the Light-Projected Children

The projected-children puzzle is about following, not about pressing buttons.

How the mechanic works

You do not directly control the projection. Your movement determines where the projected child can follow, so guide it along the connected route instead of moving straight to the target.

Verification pending

Use the marked Shift surface to continue.

Shift is not confirmed as a requirement for this puzzle yet.

Projection not moving?
  • Is the projection still following you?
  • Are you on the correct connected route?
  • Did you miss the previous interaction?
  • Are you trying to skip directly to the target?

The exact ordering of the projections and their route steps is still being verified, so this module explains the mechanic and the checks instead of inventing a route.

Stuck on The Underpass Fault?

What's happening?

Why can't I continue?

It is usually a missing requirement, a wrong route, an unfinished objective, a puzzle state, or a known issue. Check which one applies before calling it a bug.

  • I can't reach Orange Pipes Island

    Reach is not unlocked. Complete The Subway Fault first, then come back to the island.

  • I have Reach but can't find the route

    Look for the orange pipes, the separated floating platforms, and the Reach Points between them.

  • The marker is on the island but nothing is there

    The Fault is inside the island. Find the side opening into the pipe structure and follow the interior route.

  • I can't find the TV

    Follow the interior path to the end. The TV is the interaction point, not a door.

  • The projected child won't move

    The projection follows your movement along a connected route. Do not skip straight to the target; check the puzzle diagnostic above.

  • The puzzle route looks impossible

    Check for a missed interaction, the wrong projection state, a missing ability traversal, or the wrong platform sequence.

  • The ritual doesn't complete

    Check for a remaining interaction or an unfinished dialogue or objective. Only then look for a known issue.

Known issue

Only problems listed in the updates registry are labelled as known issues.
