Every Piece and Its Location
| Piece | Location and Approach |
|---|---|
| A | Common Room: check the long dining table beside the orange chairs. |
| E | Common Room: look beneath the coffee table, on the round rug. It shares this location with Q and R. |
| Q | Common Room: search the round rug under the coffee table, together with E and R. |
| R | Common Room: check the same round rug beneath the coffee table as E and Q. |
| F | Common Room: go to the upstairs office and inspect its green console. |
| J | Common Room: look up at the hanging ceiling lamp near the Norček sign. |
| M | Dahne's Laboratory: follow the upper stair walkway and check its railing. |
| N | Dahne's Laboratory: inspect inside the first elevated fan ring in the pale-green tunnel. |
| O | Dahne's Laboratory: find the orange prototype and check the nearby workbench shelf. |
| P | Prototype test area: check the upper-floor white machine near the CONTROL ROOM door. |
| S | Prototype test area: inspect the white counter beside NO ENTRY and the marked cube. |
| T | Prototype test area: find the storeroom by the stairs and check the stacked cardboard boxes. |
Follow the Collection Route Through Headquarters
- Search the Common Room, accessible from 2-2 Wellness Check. Cover the dining table and coffee-table rug, then check the upstairs office console and the ceiling lamp near the Norček sign. This covers A, E, Q, R, F, and J.
- Search the prototype test area, accessible from 2-4 Experimental Prototypes. Find P on the upper-floor white machine near CONTROL ROOM, S on the counter beside NO ENTRY and the marked cube, and T on the storeroom's stacked cardboard boxes by the stairs.
Coordinate the Search With Your Partner
Both Explorers can collect pieces and place them on the board. Split the listed landmarks between you and call out each letter as you collect it. Keep a shared checklist so you can return to a specific landmark when a letter is still missing.
Your tools serve different purposes along the cooperative route. The Hook Gun connects to compatible targets to pull mechanisms, interact with objects at a distance, and reach certain elevated positions. The Goop Gun creates solid cubes that support movement and activate pressure-based devices.
Pay particular attention to the elevated landmarks: J is on a ceiling lamp, N is inside an elevated fan ring, and T is on stacked boxes. Locate the piece before planning your approach with your partner. Use the sign, tunnel color, or nearby stairs to make your callouts clear.
Assemble the Board and Check the Result
- Return the collected pieces to the jigsaw board in the headquarters Common Room. Either Explorer can place them, so decide who will handle the board while your partner checks the remaining letters.
- Place each piece in its matching lettered position until all 12 slots are filled. Work from the letters when checking your progress, and compare any empty position with the locations table.
- Once the picture is complete, listen for the completion sound and inspect what the finished puzzle reveals. The assembled image depicts a stained-glass chapel interior, with something additional revealed for you to examine.
The jigsaw is optional and does not award its own achievement. Complete it if you want to see the finished picture and its additional reveal. You can treat that reveal as the reason to finish the collection.
Track Down a Missing Letter
- If E, Q, or R is missing, revisit the round rug beneath the Common Room coffee table. These are separate pieces sharing the same landmark, so finding one does not finish that spot.
- If the Common Room search feels complete, check the other collection areas against your missing letters. M, N, and O belong to Dahne's Laboratory; P, S, and T belong to the prototype test area.
- If the board still has an empty position, use its letter to choose your next search. Check that exact row in the table with your partner before repeating a sweep of an entire room.
