To unlock Time to Crate in Mission 10, Stranded, open every Yellow Supply Crate until the mission counter shows 26/26. The current cache count is 26: 24 fixed caches, one cache on a moving train and one cache in a patrol convoy truck. The achievement unlocks immediately when the last crate opens.

What the Stranded puzzle requires
The puzzle is a collectible sweep rather than a single riddle. Your objective is to open all 26 Yellow Supply Crates in Stranded. Eight locked locations require keypad or bunker codes, while the remaining caches are reached by exploring containers, buildings, sewers, cliffs, river areas and enemy outposts.
Mission 10 keeps a running on-screen total labeled Yellow Supply Caches Opened. The counter persists during the mission, so you can collect in any order. When the last cache opens, the display should read SUPPLY CACHE 26/26, followed immediately by the Time to Crate unlock.
#1 Best Overall
- 【Strong Adsorption】The inspiration of the silicone phone suction case comes from the adhesive force of the octopus. Each suction cup phone mount is 3.15 inches long and 2.17 inches wide, with 24 independent suction cups providing a stronger and more stable suction force, so you don't have to worry about your phone falling during use.
- 【Back of Phone Suction Grip】Remove the adhesive film on the phone suction cup and stick it on the phone case. You can then fix the phone on any smooth surface, which is very convenient. (The phone suction cup cannot be removed and reused after being attached to the phone case. It is recommended to attach it to a regular phone case, not a valuable one.)
- 【Widely Used】Our non-slip silicone phone sticky grip mount attaches to almost any flat phone case and make it compatible with common mobile phones such as iPhone and Android.You can shoot, watch videos or video calls in the kitchen, gym, dance studio, bathroom and other places.
- 【Capture the Wonderful Picture】Whether you are a TikTok creator or just like to share videos and photos, this phone suction cup can help you hands-free capture wonderful videos and photos for sharing with friends.
- 【Note】You can fix the phone suction cup on a smooth surface such as a mirror or glass. If necessary, wipe the suction cup with a damp cloth to obtain stronger suction. Before releasing your hand, make sure the phone is firmly fixed. (Not applicable to rough walls, wooden surfaces, and other uneven surfaces)
Set up your route before opening crates
Start at Base Camp
At Base Camp, open the shipping container beside the radio tower by entering 0024. Its wall map marks locked containers and bunkers across the mission area. Use that map as your route planner instead of relying on memory.
Use the counter as your checklist
Check the total after every cleared area. A location that appears complete can still hide a crate behind a blocked entrance, inside a sewer route or on a moving vehicle. The counter is more reliable than a hand-written list because it records only crates that have actually been opened.
Clear outposts before making long trips
Several caches become accessible only after their guarding outpost is cleared. Clearing outposts also makes Tac Map travel and fast travel more practical. After an outpost is secure, open the map, select the next marked area and travel there rather than crossing the whole map on foot.

- SUPERIOR COMFORT — Unlike traditional circular ear buds, the design of EarPods is defined by the geometry of the ear. Which makes them more comfortable for more people than any other ear bud–style headphones.
- HIGH-QUALITY AUDIO — The speakers inside EarPods have been engineered to maximize sound output and minimize sound loss, which means you get high-quality audio.
- BUILT-IN REMOTE — EarPods with USB-C plug also include a built-in remote that lets you adjust the volume, control the playback of music and video, and answer or end calls with a pinch of the cord.
- COMPATIBILITY — Works with all devices that have a USB-C port.
- INTEGRATED MICROPHONE — A built-in microphone precisely captures your voice while you’re on the phone, taking a FaceTime call, or summoning Siri — so you’re always heard loud and clear.
Choose between two sensible route styles
- Fixed-first route: clear outposts, visit every marked container and bunker, then handle the train and convoy. This minimizes backtracking and lets you use fast travel.
- Moving-cache route: take the train and convoy as soon as you are near them. This removes the two timing-sensitive caches from your mental checklist, but you may need to wait for another train cycle or patrol if you miss one.
If you are also working toward Noteworthy, combine the crate sweep with note collection. Stranded contains 58 notes, and 50 are required for that achievement according to the 2026 iTechGuides count.

All eight Stranded keypad and bunker codes
Enter all four digits exactly as shown, including leading zeroes. The clue patterns are useful if you want to solve the locks yourself, but entering the known code is faster on a cleanup run.
| Location | Code | How the clue resolves |
|---|---|---|
| Base Camp shipping container beside the radio tower | 0024 | Earlier codes are 0006, 0012 and 0018; each increases by 6. |
| Cliff north of Base Camp | 0600 | The first pair drops by 3, the second digit rises by 1, and the final two digits stay 00. |
| Container south of Jamming Station | 8609 | The first digit rises by 1, the second falls by 1 and the final pair increases by 2. |
| Big Sign container | 1234 | The sequence adds one digit at each step. |
| Small river-island container | 6789 | It continues the 3456, 4567 and 5678 sequence. |
| Southeast village, Infantry Checkpoint 4 | 0078 | The earlier codes increase by 22. |
| Riverbed bunker below the bridge | 0008 | The code is the sum of the river infantry-checkpoint numbers. |
| Farm-field hidden bunker | 0330 | Add the Logistics station values: 100 + 200 + 10 + 20. |
When a keypad rejects an entry, re-enter every digit, including the zeroes at the beginning. A four-digit code such as 0024 is not interchangeable with 24.

How to clear the 26-cache sweep
1. Open the Base Camp container and read the wall map
Enter 0024 in the container beside the radio tower. The interior map identifies locked containers and bunkers, giving you a visual plan for the fixed locations. Open the cache inside before leaving so the counter advances.
2. Clear each marked outpost before searching its cache area
Work through the outposts shown on the Tac Map. Some doors and approaches remain inaccessible while enemies control the area. Once an outpost is clear, search the surrounding structures, use fast travel to the next cleared point and verify the counter before moving on.
Do these 3 things before closing this tab:
1Repair Windows errors before they cause bigger problems2Scan for outdated or missing drivers - takes under a minute3Clear out junk files and repair common Windows errors3. Search containers and bunkers methodically
At each marked location, look for the yellow cache prompt rather than assuming that opening a nearby door completed the area. The known locked locations are the cliff north of Base Camp, the container south of Jamming Station, the Big Sign container, the small river-island container, the southeast village at Infantry Checkpoint 4, the riverbed bunker below the bridge and the hidden farm-field bunker. Use the codes in the table as you reach them.

4. Break the blockage at Infantry Checkpoint 6
One container is hidden behind wooden crates at Infantry Checkpoint 6. Destroy the crates first, then enter the newly accessible container and open the cache. If the counter does not move, make sure you opened the yellow supply cache itself rather than only clearing the obstruction.
5. Follow sewer routes and climbing paths
Some fixed caches are not reached by a straight walk from their map marker. Check for sewer entrances, climbable edges and alternate approaches around structures. Tripwires can block a direct path; clear them before attempting to pass. If a marker appears close but no cache is visible, search below ground and above the surrounding roofline before abandoning the area.
6. Board the moving train for its cache
Wait beside the tracks for the looping train. Board at the front of the moving train, then search the train for the yellow cache and open it. This is one of the two non-fixed caches, so it will not remain at a permanent map location. If you miss the jump or the train leaves, stay near the tracks and wait for its next loop rather than marking the area complete.

7. Loot the convoy truck near Infantry Checkpoint 3
Watch for the patrol truck near Infantry Checkpoint 3. Clear the patrol, approach the truck and open the cache in its rear. This convoy cache is easy to overlook because the vehicle moves through the area; killing nearby enemies without checking the truck does not count as collecting it.
8. Confirm 26/26 before leaving Stranded
After every major section, compare the total with the number of caches you intended to collect. The final opening must display SUPPLY CACHE 26/26. The achievement should unlock at that point, without a separate menu action.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Why some guides say 25 and others say 26
An earlier PowerPyx page lists 25 Yellow Supply Crates. Later guides dated October 17–18, 2026 identify 26 and account for the train and convoy-truck caches. The practical test is the in-game counter: if it reads 26/26, you have met the completion condition; if it stops at 25/26, one cache is still missing regardless of which older list you followed.
Finding the cache you missed
If the counter is 25/26
- Return to the Base Camp wall map and compare every marked fixed location with your own route.
- Recheck the seven non-Base-Camp locked locations using the codes above.
- Inspect Infantry Checkpoint 6 for the wooden-crate blockage.
- Revisit the train tracks and wait for the next loop, boarding at the front.
- Search the rear of the convoy truck near Infantry Checkpoint 3 after clearing its patrol.
- Review sewer entrances, climbing routes and tripwire-blocked paths around locations that appeared empty.
If the code will not work
- Confirm you are at the correct location; several containers and checkpoints look similar.
- Type all four digits, including leading zeroes.
- Read the keypad prompt again after clearing the local outpost, since some entrances remain unavailable while enemies are present.
- After opening the lock, search inside for the yellow cache prompt; unlocking a door alone does not increase the total.
If the achievement does not appear immediately
Look for the on-screen SUPPLY CACHE 26/26 message. If the counter has not reached 26, the unlock condition is not complete. If it has reached 26 but the notification is delayed, allow the mission state to settle before exiting. Difficulty does not prevent the unlock.
Can you finish the collection in a replay?
Yes. Mission replay or mission selection can be used for cleanup. Stranded keeps enough of its collectible progress separately for a later run, so you do not have to restart the entire campaign to find one missed crate. On a replay, open the Base Camp map first, use the known codes, and prioritize the train and convoy caches if your earlier run covered most fixed locations.
What counts as a successful completion?
- All 26 Yellow Supply Crates are open.
- The counter reads 26/26.
- The achievement Time to Crate unlocks immediately after the final cache.
- The trophy description is:
Open every Yellow Supply Crate in ‘Stranded.’
Use the counter, not an older online list, as the final authority. A route is complete only when the game itself records 26 out of 26.
