The Impermanence puzzle at Testing Facility Broadway blocks the facility shutdown until every marked floor zone holds the correct object. The room is filled with appliances that change shape when you throw them, and the console lever refuses to work until all of them settle on a single form. The fix is consistent and repeatable once you know what the shutdown instructions are asking for.
Quick answer: Throw each shifting appliance until it becomes a Soda Dispenser (“Thirst Station”), place one in every yellow floor square, then pull the console lever to trigger the shutdown.
Reaching Testing Facility Broadway in West Incursion Zone 4
Testing Facility Broadway sits in West Incursion Zone 4, near Evacuation Zone 7. The entrance is through the sewer system, so you drop into an excavation pipe and work through the tunnels to reach the control area. Expect Hiss enemies along the way, so clear them before you settle in at the console.
Once inside the main Broadway control room, read the “Shutdown Instructions” document on the desk. It states that all designated Impermanence areas must be in their default state, and that the default state is set as a Soda Dispenser. Only when every zone matches that state will the lever complete the shutdown.

Every collision makes an Impermanence object switch to another shape. Slam it into a wall or the floor, or simply drop it, to roll a new item—possibly a sink, stove, copier, or soda dispenser. Continue tossing that same object until it becomes the Thirst Station soda dispenser.
- Pick up a shifting appliance and throw it repeatedly until it reads THIRST STATION.
- Only the soda dispenser form counts; copiers, sinks, and stoves on a square do not.
- You cannot drop an object while carrying it into place, so line up the form first.
- Every yellow floor outline must hold one Thirst Station.
If you pull the lever early, it triggers an error buzz and highlights that a zone is still unresolved. Use that as a check to find any square you missed.
Fill all five yellow squares with a Thirst Station
The yellow squares are spread across the catwalks, the lower floor, the upper control platform, and a raised booth. Work through them one at a time so you do not lose track of which zones are done.





Complete the shutdown and confirm the reward
Once all five squares hold a Thirst Station, return to the console in the main control room and pull the lever again. This time it initiates the facility shutdown instead of buzzing an error. You will see the puzzle resolve and rewards register, including a West Incursion Zone 4 +120 gain and a “+1 Undefined Reading” pickup.
You know it worked when the shutdown completes and the “Quest Log Updated” notification appears. If the lever still errors, one square is holding the wrong form or is empty, so check each zone and confirm only soda dispensers remain on the markers.
