Hell is Us Codes

Hell is Us hides progress behind keypads, safes, locked terminals, emotion-based vaults, and even a radio dial. Rogue Factor deliberately omits a world map and quest markers, so when you stumble on a sealed door in the Acasa Marshes or a Ministry safe in Lethe, the answer is rarely handed to you on-screen. This hub collects every confirmed code in one place and points you to deeper write-ups when context matters.

Codes fall into five practical groups: doors and gates, safes, computers and laptops, Vaults of Forbidden Knowledge, and the Rolst office radio. Most numeric entries are fixed for every playthrough; vault sequences instead ask you to align emotional keystones you discover through Datapad Investigations and environmental clues. If you only need a fast answer while playing, open the Code Finder and filter by type or region.

Each list below is maintained separately so you can bookmark the page that matches what you are standing in front of right now.

• Door and gate codes — Vitalis basement, Observation Outpost 08, Marga Hamil’s lab, three Lethe library doors, and the Marastan control booth.
• Safe and computer codes — APC Deluxe safe, Talju loot, Rolst’s office, Ministry Room 109, Auriga observation room, Watcher’s Nest terminal, Lethe Computer Room D, Rolst’s PC, Auriga maintenance laptop, and B4 Timeloop control.
• Vault codes — Acasa Marshes and Lake Cynon emotion sequences, plus how keystones tie into Lymbic progression.

When a code comes from dialogue or a Datapad rather than a wall scribble, the child page explains where you should have heard it. That matters because Hell is Us rewards thorough investigation; rushing past NPC conversations can leave you staring at a keypad with no leads.

How codes fit into exploration

Hadea is structured around Timeloops, Good Deeds, and Vaults of Forbidden Knowledge that gate Relics, glyphs, and Lymbic weapon upgrades. A single missed safe in Talju might not block the main story, but it can delay a glyph slot or Healing Pulse upgrade you wanted before a Hollow boss. Treat codes as checkpoints on a longer route: open the door, loot the room, log the Investigation, then decide whether to push forward or backtrack through an earlier Timeloop.

Your KAPI drone can reach switches and scan clues in places Ren cannot, and several computer passwords sit behind platforming or combat rooms you will not see if you beeline toward objectives. The exploration checklist pairs well with this hub — tick off major landmarks while keeping code pages open on a second monitor or phone.

Codes versus puzzles

Not every lock is a numeric code. Marastan eagle statues, Lake Cynon forge pillars, Jeljin crypt sequences, and Watcher’s Nest wiring puzzles require spatial reasoning instead of digits. When investigation stalls, switch to the puzzle solutions guide for step-by-step layouts. Vault pages here only cover the emotion dial sequences; pillar order and statue rotations live with puzzle write-ups so each article stays focused.

Quick reference table

Type	Count	Example
Door / gate	7	Vitalis basement 321713
Safe	6	Auriga observation 77777
Computer	5	Watcher’s Nest 241244
Vault sequence	2	Acasa Marshes emotions
Radio	1	Rolst office 60 FM

Deluxe edition players also get the APC safe code 199301, which is exclusive to that SKU and easy to overlook if you are searching generic Lethe lists.

Using this hub efficiently

Read the short intro on each child page once, then rely on the Code Finder during repeat runs or New Game Plus cleanup. Update your personal notes when a patch changes keypad behavior — Nacon has shipped quality-of-life fixes since the September 2025 launch, but story-critical codes have remained stable in community testing.

If you are new to the game’s no-map design philosophy, pair this section with broader guides on Datapad Investigations and melee-plus-drone combat. Codes unlock spaces; understanding Healing Pulse timing and Hollow weak points helps you survive what waits inside.
