Stuck on a locked door or a terminal aboard the Aeterna Solis? This walkthrough follows the full-release route through all 15 puzzles, from the Stateroom switch panel to the LUX override. The fixed codes and values are listed below, while the memory, wire, frequency, laser, pipe, and final-symbol puzzles include the method you need to read the current state instead of a made-up universal pattern.
Spoiler and version note: this is a start-to-ending solution for Steam AppID 4298100, checked against the full-game route and the official information available on August 11, 2026, after Patch 1.2. The game lets you choose a timer or no timer. Use no-timer mode if you want to compare clues without repeating rooms, and make a save before the long Command Deck sequence.
The fixed answers at a glance
Use this table when you already understand the panel and only need the value. A puzzle marked read the room does not have a trustworthy one-line sequence because its visible state is the clue.
| Puzzle | Answer or rule | Success check |
|---|---|---|
| 1. Stateroom switches | Green, orange, yellow | The circular door opens |
| 2. Cryo chambers | 8807235 |
The awakening sequence starts |
| 3. Stateroom grid | 0 1 3 2 / 1 0 2 3 / 2 3 1 0 / 3 2 0 1 |
Every row and column contains 0-3 once |
| 4. Lab Deck keypad | 2356 |
Lab access is accepted |
| 6. Temperatures | Hub 20, Engineering 24, Command 21, Lab 18, Staterooms 21 | The panel reports stable temperatures |
| 8. Valves | Green 175, cyan 225, orange 275, red 125 bar | All four pressure lines stabilize |
| 13. Triangulation | X = 4, Y = 6, Z = 0 | The total is 10 and the array stabilizes |
| 14. Navigation | Arden 4, Virelon, Kaldara Prime, Novus Viridia | The plotted route turns green |
Open the ship: Stateroom, cryo code, grid, and Lab door
1. Press the Stateroom colors in the ration-can order
Inspect the short note and the ration cans marked A1 through A3 before touching the six-button panel. The working sequence is green, orange, yellow. Orange is the middle-left button on the panel; yellow is at the lower right. If the door stays shut, clear the panel and make sure you used orange rather than the adjacent red button. The circular Stateroom door opening is the only confirmation you need before moving into the central hub.
2. Wake the cryo chambers with 8807235
On the Command Deck, inspect the cryo-parameter reference and the colored chamber displays. The clue’s reading order is green, red, cyan, then orange. If you want to bypass the comparison, enter 8807235 on the terminal. Do not stop after the access message: wait for the panel to confirm that the awakening sequence has started. A rejection usually means a digit was skipped or the seven digits were entered in the wrong order.
3. Fill the 4-by-4 Stateroom grid
Return to the Stateroom grid. Columns are A through D and rows are E through H. Each row and each column must use 0, 1, 2, and 3 exactly once. Enter the rows from top to bottom as follows:
| Row | A | B | C | D |
|---|---|---|---|---|
| E | 0 | 1 | 3 | 2 |
| F | 1 | 0 | 2 | 3 |
| G | 2 | 3 | 1 | 0 |
| H | 3 | 2 | 0 | 1 |
Before submitting, scan every vertical column as well as every horizontal row. A duplicate number is the fastest way to locate a mistyped cell; changing unrelated cells after a failed check only makes the grid harder to recover.
4. Use Malcolm Meros’s birth year at the Lab Deck
The personal-data record gives Malcolm Meros’s date of birth as 06.10.2356. The door wants the four-digit year, not the day and month, so enter 2356. Once the Lab Deck opens, keep checking crates and the spaces behind large equipment. The mineral puzzle later requires items from more than one deck, and collecting them as rooms open prevents a separate ship-wide sweep.
Restore Engineering and stabilize every deck
5. Route the Engineering laser one segment at a time
The laser room is easier if you ignore the distant receiver at first. Start at the live emitter, rotate the first mirror until the beam lands on the next available reflector, and then follow the illuminated segment forward. Repeat that process at each mirror. A dark mirror is not your next target; backtrack to the last lit mirror and rotate it until a new segment appears. The route is complete only when the final beam reaches the receiver and the system changes state, so do not rely on a particular number of turns copied from another attempt.
6. Enter all five temperature targets before checking
The Docking Station terminal links several temperatures rather than giving five isolated answers. The Lab is ten degrees above the eight-degree cryo baseline, Engineering is three degrees hotter than the Staterooms, and the central hub must not exceed 20. Set the panel to:
- Central Hub: 20 C
- Engineering: 24 C
- Command Deck: 21 C
- Lab: 18 C
- Staterooms: 21 C
Press the panel’s check control only after all five rows are set. The confirmation is a stabilized-temperature message and access to the next Stateroom area. If the check fails, verify the room labels as well as the numbers; the two 21-degree entries are intentional.
7. Join the Lab pipes from inlet to outlet
For the pipe board, work from the left inlet rather than rotating every tile at random. Turn the first connected tile toward a neighboring pipe, follow that continuous path, and leave any branch that points into a blank edge disconnected. Then do the same backward from the right outlet. When the two partial paths meet, inspect every joint for an open end before activating the flow. If no liquid reaches the outlet, the bad rotation is at the first dry joint after the inlet, not necessarily near the far end.
8. Match the colored valves to their pressure labels
Back in Engineering, set the four valves to these exact values:
- Green: 175 bar
- Cyan: 225 bar
- Orange: 275 bar
- Red: 125 bar
Read the color on the line, not the valve’s physical left-to-right position. If one channel still shows unstable, compare that channel’s color and value before changing the three already accepted settings.
Find all four minerals and create the Command Deck power cell
The mineral task is the one place where an early pickup can save several minutes. Four rocks are spread across three decks:
| Mineral color | Location | Where to look |
|---|---|---|
| Blue | Starting Stateroom | In the room available at the beginning |
| Green | Stateroom | Behind a cryo pod |
| Orange | Lab Deck | Inside a crate |
| Purple | Docking Station | Inside a crate |
Bring the rocks to the extractor in the Lab. Process them, then place each resulting crystal into the tube with the matching color. A rock in your inventory is not yet a usable crystal; if the machine appears incomplete, check that every rock was extracted and every crystal moved into its tube. Completing all four tubes produces the energy cell needed to continue into the Command Deck sequence.
Read the Command Deck state: memory, wires, and frequency
10. Copy the six-light memory sequence shown behind you
Pull the lever to begin, then turn around immediately and watch the six lights on the opposite wall. Record the order by position, such as top-left or bottom-right, and reproduce it on the terminal. The order can change, so a sequence from a video is less useful than the room itself. If your input fails, pull the lever again and read the new display from the start; do not assume the failed sequence will remain active.
11. Translate the wall lights into red and blue wire states
Inspect the three pairs of lights on the wall before using the 2-by-3 terminal. A red wire represents a pair where exactly one light is on. A blue wire represents a pair whose two lights match, whether both are on or both are off. Apply that rule to each visible pair and reproduce the result on the terminal. If the panel rejects the layout, revisit the pair where you treated two dark lights as different; matching darkness still belongs to blue.
12. Align the frequencies from left to right
Begin with the left signal and wait for its white reference pulse. Count the spacing until the next signal reaches the same white point, then use the left and right controls to shift that signal into alignment. Lock it only when its phase matches the signal immediately to its left. Continue across the display. If a later channel drifts, correct that channel against its left neighbor rather than restarting with the first. The puzzle is solved when every channel reports alignment and the indicators turn green.
Finish triangulation, plot the route, and shut down LUX
13. Set X to 4, Y to 6, and Z to 0
The triangulation rules say Z is switched off, Y must be the highest value, X is two-thirds of Y, and all three values total 10. The only working set is X = 4 on the square, Y = 6 on the hexagon, and Z = 0 on the circle. Stabilize the array and wait for the success state before leaving the panel.
14. Select the four navigation targets in route order
Use the navigation table and choose the destinations in this order:
- Arden 4 at the upper right
- Virelon at the lower left
- Kaldara Prime at the upper left
- Novus Viridia at the lower right
Watch the route draw after each choice. If the table does not turn green after the fourth target, clear the plot and rebuild it from Arden 4; selecting the right four locations in a different order does not reproduce the required path.
15. Copy the navigation path into the LUX override
Do not leave the navigation result behind mentally: its center path is the clue for the final override. At the LUX terminal, cycle through the available symbols until the displayed glyph exactly matches the route shape produced by the navigation table, then confirm. This symbol should be read from your completed table rather than replaced with a static button count. A mismatch leaves the override incomplete; matching the route triggers the shutdown message and the final exterior sequence.
There is no extra combination to enter after the override confirms. If the closing sequence does not begin, the problem is the selected glyph, not the earlier triangulation values. Return to the navigation table, note the direction of every segment, and compare the full shape again.
Verified full-game video reference
The developer’s full-release announcement links the walkthrough below for stuck players. It is Akifini’s Gaming’s full-game Drifting In Silence run. The video is useful for matching a terminal or room visually; the written route above separates its fixed answers from state-dependent puzzle methods.
Sources and update boundary
Game identity, release date, features, and official screenshots were checked against the Protocol Solari: Escape Room Steam page. The release announcement and current Steam news identify the same full-game walkthrough and show Patch 1.2 as the latest listed update at the time of this check. If a later patch changes a panel, trust the labels and success states in the current client; the state-reading methods above remain safer than forcing an old visual pattern.
