What to know
- The Closed Gate Area is not a free-explore unlock; it’s tied to an infrastructure progression gate.
- Players report the trigger is raising Infra-station to Level 3, after which the upgrade quest leads into the closed-off map portion.
- If the gate still won’t open, it usually means the required Infra-station upgrade objective hasn’t been started or completed yet.
- Expect this to be a “quest unlock” rather than a hidden switch or optional lever in the immediate area.
In Arknights: Endfield, after reaching Originium Science Park, some segments remain sealed until the game flags the correct infrastructure milestone. The “Closed Gate Area” is one of those gated segments that typically opens when outpost/base development reaches the required level.
Reference table for the unlock
| Segment | What happens | What to look for on-screen |
|---|---|---|
| Getting to the locked entrance | Travel to the Closed Gate Area barrier inside Originium Science Park | A sealed barrier/gate with no manual “open” prompt |
| Finding the gate control | Move to the nearby control/terminal associated with the closed gate | An interact icon on a console/terminal |
| Restoring power | Use nearby power-related devices to supply electricity to the gate | A “no power / needs power” style state changing to “powered” |
| Opening the gate | Interact with the powered console to unlock/open the barrier | Gate animation and the path becoming passable |
How to confirm the correct gate is being targeted
| Item | What it means in practice |
|---|---|
| Locked location | “Closed Gate Area” within Originium Science Park that won’t open via normal exploration. |
| Primary requirement | Infra-station raised to Level 3 (reported community requirement). |
| What actually opens it | The Infra-station Level 3 upgrade quest path takes into the area (the unlock occurs through that quest flow). |
| Common reason it “doesn’t work” | Infrastructure level not met, or the upgrade quest chain not progressed far enough. |
The Closed Gate Area in Originium Science Park is commonly the same “uncovered map segment” players can see but can’t enter until a base upgrade quest points there. If the map shows an unreachable section behind a sealed entrance and there’s no immediate interaction that opens it, it matches the reported infrastructure gate behavior.
How to meet the Infra-station Level 3 requirement
Step 1
Open the base/outpost infrastructure management interface and locate the Infra-station level.
Step 2
Continue progressing infrastructure until Infra-station reaches Level 3.
Step 3
Check for the Infra-station upgrade quest that becomes available at that milestone, then actively track it so navigation markers and objectives update correctly.
Step 4
Follow the upgrade quest objectives; the quest route itself is what reportedly takes into the Closed Gate Area (the area becomes accessible during/after the quest steps).
Troubleshooting if the gate remains closed
If Infra-station is not Level 3 yet, the area is expected to remain inaccessible. If Infra-station is already Level 3, verify the upgrade quest is accepted and actively tracked, since the reported entry comes from that quest chain rather than a standalone “open gate” prompt.
Final notes on opening the area
The most consistent fix is treating the gate as a progression checkpoint: advance Infra-station to Level 3, then complete the resulting upgrade quest that routes into the closed section. If the goal is full map uncovering, continuing infrastructure and the associated questline is the reported path that resolves the blockage.
