How to Close Hell Is Us Timeloops and Open Every Vault
Hell Is Us timeloops are the side content that keeps Hadea dangerous, and closing them is the fastest way to make a region quiet again. Each loop keeps enemies coming back until you hunt down its Loop Guardians and seal it with your drone. Tania's research runs alongside that work and turns the junk in your pockets into codes for hidden vaults.
In our Hell Is Us review, these detours ended up among the best hours in Hadea. With no map and no quest markers, both systems reward players who take notes and revisit old areas.
This page explains how to close a loop, how the Guardian Detector changed after Patch 1.7, and what Tania research gives you.
Hell Is Us Timeloops Summary
Hell Is Us timeloops keep enemies respawning in their area until you close them.
Kill every Loop Guardian first. They look like regular Hollow Walkers, and a loud thrumming sound plays once the last one dies.
Seal the loop by giving your drone the matching Amine Prism (Theta, Sigma or Rho). Stay away from the center of the scene inside, since it drains your health.
Get the Guardian Detector from Gildas Brom at the Watcher's Nest. Since Patch 1.7 (July 23, 2026), it also tracks every remaining Lymbic Entity in an area once its loop is closed.
Hand research items to Tania in the APC. A full research bar gives you the location and symbol code of a Forbidden Knowledge Chamber.
6 vaults and 45 research items await, and none are missable.
How Do You Close Hell Is Us Timeloops?
You close a timeloop by killing all of its Loop Guardians, walking into the loop and loading the right Amine Prism into your drone. The loops are large black spheres, and each one keeps the Hollow Walkers in its area respawning. That's why ground you already cleared fills up again.
Step | What you do | Watch out for |
|---|---|---|
1. Find the Guardians | Track the Loop Guardians tied to that loop | They look exactly like regular enemies |
2. Confirm the clear | Kill them until a deep thrumming sound plays | A pop-up confirms each Guardian kill |
3. Enter the loop | Walk inside and reach the replayed scene | Standing near the center damages you, then kills you |
4. Seal it | Use your drone with the matching Amine Prism | Theta, Sigma and Rho prisms aren't interchangeable |
Gildas Brom hands over your first Amine Prism. Later ones come from Good Deeds and Mysteries, Lymbic Chests and Lymbic Doors, and the technicians at the Auriga Museum. Short on the right type? Finish a few side requests first.
Closing a loop stops the respawns for good, but the Hollows already standing there remain. Gildas Brom pays out Glyphs and Relics for each sealed loop.
Loop Guardians and the Guardian Detector After Patch 1.7
The Guardian Detector is the tool that makes timeloops bearable. You get it from Gildas Brom at the Watcher's Nest, slot it into your quick slots, and it points toward the nearest Loop Guardian.
Since Patch 1.7, released on July 23, 2026, the Guardian Detector also picks up every remaining Lymbic Entity in an area once you close its timeloop. Rogue Factor tied the change directly to the Legend of the Phol achievement, which asks you to close every loop and clear every leftover Hollow in each area.
Hollows hide in tunnels and side paths, and in the shallow pools of the Acasa Marshes some stay invisible until they stand up to attack. Before the patch, finding the last one by hand could eat an entire evening.
Nothing here is missable. Every loop remains available after the story ends, so you can leave a stubborn region for later and come back with better gear.
Tania's Research Turns Junk Into Vault Codes
Tania, a journalist, joins you in the APC during Act 1 and studies the strange objects you pick up. According to Nacon's official Hell Is Us tips, a full research bar reveals the exact location of a Forbidden Knowledge Chamber and the symbol code that opens its door.
The game has 45 research items spread across themed sets such as Ancient Hadea, Order of the Eye and The Civil War. Finishing a set earns its own achievement, and collecting all 45 gives you the gold Well-Read trophy.
Vault | Region |
|---|---|
Vault of the Copse | Senedra Forest |
Vault of the Mire | Acasa Marshes |
Vault of the Knoll | Vyssa Hills |
Vault of the Mere | Lake Cynon |
Vault of the Prairie | Jeljin |
Vault of the Beck | Marastan |
Inside the six vaults you'll find Glyphs, weapons, Relics, Tuning Stones and extra Amine Prisms, which loops your research back into closing timeloops. Jot each symbol code next to its region as soon as Tania shares it, so you can walk straight to the right door. With no map to lean on, it's the best case the game makes for keeping a notebook next to the controller.
FAQs About Hell Is Us Timeloops
Final Words
Timeloops and Tania's research feed each other. Vaults hand out Amine Prisms, prisms close loops, and closed loops make it safer to search a region for the next research item.
Patch 1.7 removed the worst chore in the whole system. Hunting the last invisible Hollow in a swamp used to decide whether you finished Legend of the Phol, and now the Guardian Detector simply shows you where it is. That fix pulled us back into Hadea this summer, and the loops we had abandoned fell much faster. If you shelved the game before July, it justifies a return on its own.
Keep notes as you go. The datapad logs your Good Deeds and clues, but NPCs give directions as compass bearings and landmarks, and a page per region turns those into a route.
