The sealed chest at Shorecove Camp is an early exploration puzzle in Arknights: Endfield that rewards careful observation rather than combat strength. At first, the chest appears impossible to open, sitting on a rooftop with no clear switch or key in sight. However, the solution is hidden in the environment itself, using destructible objects, explosives, and vertical movement.
If you are exploring Valley IV and do not want to miss useful early-to-mid game rewards, this guide explains exactly where the chest is, how the puzzle works, and how to unlock it step by step without wasting time. Also check out our Arknights Endfield Codes for more rewards!
Where to Find the Shorecove Camp Sealed Chest
Shorecove Camp is located in Valley IV, an area commonly referred to as The Hub during early exploration. The sealed chest is placed on top of a flat rooftop overlooking the lower camp platforms.
You can see the chest fairly early if you look toward elevated structures, but reaching it immediately will not work. The area below the rooftop is packed with wooden barricades, crates, and supports. These objects are not decoration, they are part of the puzzle that blocks access to the chest’s unlock condition.
How the Sealed Chest Puzzle Works
This chest does not open through combat or switches. Instead, it requires interaction with the environment. The seal is linked to four glowing collectibles placed around the camp. Explosive barrels and destructible terrain nearby act as subtle hints. The game expects you to break obstacles, explore inside structures, and move vertically to locate all required items. Once all four shiny objects are collected, the seal disappears automatically.
Step-by-Step Guide to Opening the Chest
Step 1: Locate the Sealed Chest
Start by climbing onto the rooftop and interacting with the chest. The sealed status confirms that extra steps are required. Take a moment to observe nearby buildings, platforms, and blocked paths.
Step 2: Learn the Four Shiny Object Requirement
The chest unlocks only after collecting four glowing objects hidden around Shorecove Camp. They are all nearby, but some are blocked by terrain or height differences.
Step 3: Collect the First Shiny Object
The first collectible is placed very close to the chest, usually on the same rooftop or just beside it. This acts as a hint that the solution is nearby, not across the map.
Step 4: Use Explosives to Find the Second Shiny Object
This step requires environmental destruction. Look for explosive barrels or throwable charges near the opposite structure from the chest. Use them to destroy wooden barriers and crates near the base of the building. Once the debris is cleared, an interior area becomes accessible.
Extra Loot Inside the Structure
Before grabbing the collectible, explore the opened room. Inside, you can find supply crates containing:
- Orobeyl
- Protoprism
- T-Credits
These rewards make the puzzle more valuable than it first appears.
Finding the Glowbug
Inside the structure, look across from the blue supply crates. A glowbug can be found here. Interacting with it grants the second shiny object.
Step 5: Reach the Third Shiny Object Above the Structure
Exit the building and look upward. The third shiny object is placed above the structure you just entered. Use nearby beams, ledges, or containers to climb. This section focuses on careful jumping rather than destruction, so adjust your camera and take your time.
Step 6: Collect the Fourth Shiny Object on Stacked Containers
The final collectible is positioned on high containers to the right side of the structure. This is the most platform-heavy part of the puzzle. Jump across stacked crates and containers until you reach the highest platform. Falling means repeating the climb, so move slowly and plan your jumps. Once reached, collect the fourth shiny object.
Step 7: Open the Sealed Chest
Return to the rooftop where the sealed chest is located. With all four shiny objects collected, the seal will be removed automatically. You can now open the chest and claim the rewards.
Rewards From the Shorecove Camp Sealed Chest
- Orobeyl 100
- T-Credits 2,450
- Intermediate Combat Record 2
- Protodisk 1
- Arms INSP Kit 2
- Protoprism 1
These rewards are especially useful during early progression, where Combat Records and Protodisks often slow down upgrades.
This sealed chest acts as a quiet tutorial for how Arknights: Endfield handles exploration puzzles. Instead of obvious markers, the game relies on object placement and environmental clues. By completing this puzzle, you learn to:
- Check for destructible objects in locked areas
- Look upward when exploring, not just forward
- Revisit visible chests after opening new paths
These habits are reused throughout Valley IV and later regions.
Some players try to bypass the puzzle by reaching the chest from above. This does not work, as the seal cannot be ignored. Others waste explosives by detonating them too far from barriers. Explosions have limited range, so placement matters. Another common mistake is skipping the interior area after breaking obstacles, which leads to missed loot and delays unlocking the chest.
Tips to Solve the Puzzle Faster
- Carry explosives before exploring sealed areas
- Fully destroy obstacles before moving on
- Loot interiors before returning to the chest
- Adjust the camera upward during exploration
These habits reduce backtracking and help with similar puzzles later.
