Stranded Collectibles: What You Need to Find
There are 58 notes available across the map, but players only need to collect 50 to unlock the corresponding achievement or trophy. The mission also contains 26 yellow crates, many of which are hidden inside outposts, shipping containers, bunkers, and other structures.
Collectible or Objective | Requirement |
Notes | Collect at least 50 of 58 |
Yellow crates | Find all 26 |
Scavenger | Repair everything at the base camp |
Incoming | Destroy the incoming reinforcement vehicles at the SAM site |
Supplies should be collected throughout the mission because they serve as currency for purchasing equipment and completing base camp repairs.
Start at the Base Camp and Radio Tower
At the beginning of Stranded, search around the base camp for notes related to the tactical boots, snow ghillie suit, silenced sniper, and grenade launcher. Since the mission revisits this location, missed collectibles can be recovered later.
Outside the camp, head toward the radio tower and collect the note on the storage container. Enter code 0024 to open the nearby crate and collect its supplies and map.
Climb the tower using the ladder and pipes to reach the upper platforms. Additional notes and a yellow crate can be found along the way, including near the top. Continue exploring the surrounding storage containers and use the map to follow an efficient route across the region.
Explore the Jamming Station and Northern Outposts
The northern section of the map contains several valuable collectibles. Fast-travel to the main objective near the jamming station, clear the enemies, and search the surrounding buildings.
Important locations include:
· The large two-story building, which contains a note on a desk.
· The helipad, where another note can be found.
· The communications building, which contains multiple notes near the entrance, stairs, and computers.
· The upper section of the communications structure, where a yellow crate is located.
After destroying the jamming tower, parachute toward the nearby silo with two shipping containers. Search both containers for notes and enter code 8609 to open the locked container containing a yellow crate.
Continue through the northern outposts and nearby settlements. Search command buildings for yellow crates and intel, inspect fallen enemies for notes, and check houses carefully. In the town with a plane lodged in a yellow building, enter through the rooftop opening to find a note and a yellow crate.
At the artillery battery outpost, destroy the boxes blocking access to the container using an explosive, drone, or vehicle to reach another yellow crate.
Keypad Codes and Hidden Containers
Several collectibles are concealed behind locked shipping containers and bunkers. The following codes are important during the mission.
Location | Keypad Code |
Radio tower container | 0024 |
Northern storage container | 0600 |
Silo shipping container | 8609 |
Shoreline container | 1234 |
Southern town container | 0078 |
Northern bunker | 0330 |
Southern cliffside bunker | 0008 |
Another container on the island in the middle of the river uses code 6789. Search the island and surrounding shoreline carefully, as enemies may occupy nearby watchtowers.
Inside the bunkers, collect the notes near the keypads before entering. Some bunkers also contain yellow crates, while others primarily provide additional information and supplies.
Complete the SAM Site and Incoming Achievement
Before destroying the SAM site, search the approach road for a collectible inside a nearby building. At the objective itself, collect the item on the concrete slab, the yellow crate near the statue, and the note on the box above the crate.
To earn the Incoming achievement or trophy, prepare before triggering the reinforcement sequence. Equip drones, mines, and other suitable equipment, then use them to destroy the incoming vehicles. Clearing the area beforehand makes the encounter easier to manage.
Continue south along the coastline, searching abandoned buildings, outposts, statues, and cliffside structures. Activate the generator near the large elevator shaft to reposition the elevator, then use the surrounding ledges and stairs to reach the upper area containing additional supplies and a yellow crate.
Solve the Sewer Puzzle and Collect Remaining Crates
South of the base camp, locate the blue sewage station. Collect the note inside before descending into the sewer with night vision or a flashlight.
The two movement sequences are:
· First puzzle: Up, Right, Up, Up, Left, Left.
· Second puzzle: Up, Right, Up, Left, Up, Left, Left, Down.
Avoid taking shortcuts or making incorrect moves, as the traps can be fatal. Checkpoints provide another opportunity to retry the sequences. Once the room opens, collect the supplies, note, and yellow crate before leaving.
Continue searching southern outposts, town buildings, statues, water tanks, and abandoned train cars. One yellow crate is aboard a moving train, while another travels on a cargo truck. Use the tracking device from your backpack to follow the signal and intercept the truck if the crate does not appear immediately.
Finish the Bunker and Unlock Scavenger
The final bunker area contains the last yellow crate, located to the left of the entrance. During the mission, search benches, side rooms, and elevated ledges for additional notes and supplies. Players looking for alternative gameplay experiences can also explore cheap CoD Modern Warfare 4 Bot Lobbies while progressing through the game's challenges.
Before completing Stranded, return to the base camp and purchase or repair everything available, including grenades, Molotovs, and Semtex. Completing all required repairs is essential for the Scavenger achievement or trophy.
By systematically exploring each region, entering the correct codes, solving the sewer puzzles, and collecting supplies along the way, players can complete the Stranded collectible challenges without repeatedly searching the entire map.
