What to know
-
Sealed chests in Endfield usually open after you interact with three nearby shining “orbs” linked to that chest.
-
Hub West specifically has a puzzle chest whose required orbs are meant to be close and straightforward to locate.
-
Some Hub-area chests are progression-gated, so if the area seems blocked, advancing the quest can matter.
-
Vertical exploration matters: check ledges, rooftops, and the tops/insides of crates near the chest area.
A sealed chest in Hub West is essentially a small local puzzle: the game wants you to spot and activate a few nearby “seal” objects (the glowing orbs), then return and open the chest. If you treat it like a tight-radius sweep (instead of a long detour), you’ll usually finish it quickly.
Where this sealed chest is

You’ll run into this sealed chest in Hub West, near the UWST Research Center area, around the time you’re on the Rally and Unite quest. Hub West is part of Valley IV (The Hub), the early large zone that’s packed with collectible chests.
How the sealed-chest “orb” mechanic works
When a chest is sealed, it’s locked until you interact with the shining objects associated with it.
In practical terms, that means:
-
Approach the sealed chest and interact with it so you know it’s the correct puzzle chest.
-
Look around the immediate area for glowing, interactable “orbs” (they can look like small shining objects).
-
Once you’ve activated all of them, return to the chest and open it.
How to search efficiently around UWST Research Center

Don’t just search in a flat circle—search in layers.
Check these in order:
-
The ground-level path and corners near the chest (behind small props, railings, and machinery).
-
The tops of nearby crates and containers (you may need to climb).
-
Inside or behind crates or fenced-off nooks if there are openings you can slip into.
-
Any nearby ledges above you (scan upward and look for a faint glow).
What to do if you can’t find the last orb
If you’re stuck at 2/3 (or you can’t see any orbs at all), it’s usually one of these issues:
-
You missed a vertical spot: one orb is slightly above you on a crate stack/ledge.
-
It’s tucked behind an object: walk around the back side of machinery and crate piles.
-
The route is “obvious but indirect”: a short climb path or small detour leads to a viewpoint over the chest.
-
You’re early: some areas in The Hub have access that opens up as you progress quests.
Chest context: Hub West vs nearby puzzle chests
Hub West is known to have a small number of chests total, and its puzzle chest is described as having easy-to-find orbs, which usually means you won’t need a multi-area chain of steps.
By contrast, other sealed chest puzzles in The Hub can require environmental tricks (like using explosives or finding a hidden access path), so Hub West is typically simpler—more “spot the three nearby interactables” than “solve a long traversal challenge.”
Hub West sealed chest checklist you can follow
Use this quick checklist if you want to be systematic:
-
Interact with the sealed chest once (confirm it’s the puzzle chest).
-
Rotate the camera 360 degrees and look for any glow at eye level.
-
Look up: scan rooftops/ledges and the tops of crates.
-
Climb the nearest crate stack and scan again from above.
-
Walk the perimeter of the immediate area (including behind machinery).
-
Return to the chest after each orb interaction to see if it’s ready.
If you’re following the Rally and Unite flow and you’re in Hub West near UWST Research Center, the solution should be localized: find the nearby shining orbs, interact with them, and the chest will open. If it still doesn’t, the fastest “fix” is to progress the quest slightly and come back with any newly opened access routes.
