Wall Chain Protocol: reach the Zone 4 rooftop

Wall Chain Protocol is on the roof of the tall Zone 4 building after the first combat encounter and before the first chest. Look for the broken upper building floating above it. Grapple partway up, destroy interior ceilings to keep climbing, then jump outside and double-jump back onto the solid roof.

Follow these steps

  1. Identify the building before climbing

    After the first Zone 4 fight, look toward the first chest for the tall building with a broken upper building suspended above it. The pickup is on the lower building's actual roof, not in the floating fragment.

  2. Grapple up, then open the next ceiling

    Use a nearby grapple point to get partway up. From inside, destroy the ceiling above you and climb through. Repeat through the destructible floors. Nearby buildings and grapple points can vary with the generated area, so follow the building itself.

  3. Go around the final roof

    When you reach a ceiling that does not break, you have reached the roof described in the community route. Jump outside the building, then double-jump back onto the top. Collect the schematic on the roof.

Completion signal

Collect the schematic on the roof. Mark Wall Chain Protocol as found in your checklist after the pickup; checking a box here does not unlock anything in the game.

If it does not work

If the last ceiling does not break, use the outside double-jump approach. Do not try to walk across the floating broken building: the documented route notes that it has no collision. Comments also describe wall-running up the exterior, but that alternative is not required here.
