Fuse puzzles: both panels, answered
Cargo Elevator: the missing fuse hangs from the robot arm — one lowers it, the other grabs it. Temporal Research Centre: top row orange, empty, green, purple; bottom row green, purple, orange, empty.
The answer
There are two fuse puzzles in the game and they are searched as one. They do not share an answer.
Chapter 2, Cargo Elevator — the missing fuse. The sixth socket is empty and the fuse hangs from the robot arm above it. One player pulls the lever to lower the arm; the other grabs the fuse with the pull gun. Seat it, then find the purple card through the anti-gravity room and the green card you can see from the upper walkway, put both cards in their slots, and pull together.
Chapter 5, Temporal Research Centre — the eight-slot panel. The nearby diagram is a warning: it says, in effect, avoid this placement. Reproducing it anyway is what makes the machine respond. Read the slots left to right:
| Row | Slots, left to right |
|---|---|
| Top | Orange → empty → green → purple |
| Bottom | Green → purple → orange → empty |
Leave both empty positions unfilled. Then go to the two crystal mechanisms the panel unlocks, one for each of you.
The first answer is confirmed by two independent sources. The second comes from one written source with no timestamped video behind it — read the note at the bottom before you trust it over your own screen.
Why the warning diagram is the answer
This is the part that costs pairs twenty minutes. Every other panel in the facility shows you the state you are supposed to reach. This one shows you a state the facility says is dangerous, and the instinct is to treat it as a decoy and look for the real pattern somewhere else.
There is no other pattern. The puzzle is a test of whether you read the board literally. The warning is about what the arrangement powers, not about whether it is the input.
What it unlocks is the pair of crystal mechanisms; both of you have to reach your own before the next stretch opens, which is why a pair that solves it alone still stalls.
The four ways this panel goes wrong
- A pale fuse read as an empty slot. Empty and pale-coloured are not the same thing on this panel, and the partner reading the diagram is the one who has to make that call. Describe the shape, not the brightness.
- Filling every slot. Eight slots does not mean eight fuses. Filling the two empty positions breaks the arrangement.
- Reading the rows bottom-up. The board is two rows of four and is read top row first. If your partner lists colours in a different order, stop and agree on a direction before anyone touches a fuse.
- Using the flashing panels' logic here. Some earlier fuse panels in the facility flash the slot that wants filling — those are a different interaction with a different rule. Follow their active indicator, then come back to this one and read the two rows.
If the panel accepts nothing at all
Check three things in this order, because they account for almost every failure we have seen described:
- Power. The TRC power restoration has to be finished before this panel responds. A fully powered machine gives audio feedback on a rejected arrangement; a dead one gives nothing.
- The empty slots. Two of them, and they must stay empty through the whole input, not just at the end.
- Your partner's row. If one of you is reading the diagram upside down — which happens when you approach from the far side of the room — every colour is in the mirror position.
The two puzzles people confuse with these
- The Cargo Elevator fuse is a pickup, not a pattern: it is a physical object on a robot arm.
- The 15-button G-46C panel is in the same wing as the eight-slot fuse and gets searched alongside it, but it is a button grid with a fixed four-button answer, written out on the symbol panels page.
Where this was checked
Cargo Elevator fuse: two independent sources, both describing the lever, the pull gun and the two key cards the same way. TRC eight-slot arrangement: one written source only, dated 21 October 2026, with an official store screenshot of the diagram but no timestamped playthrough that shows the input being accepted. It is printed here because the alternative is a page that says nothing about the most-searched Chapter 5 panel, but treat it as unconfirmed: if your diagram shows different colours, trust the diagram and read it left to right, top row first. Build checked: 1.1.2, 23 October 2026.
