Are you preparing to tackle the intricate Lethe Ministry and Lethe Library puzzles in Hell Is Us? These challenging environmental riddles demand careful observation and clue interpretation to uncover essential passwords. Unlike the expansive outdoor regions you’ve previously explored, these locations feature confined indoor spaces that require methodical investigation.
While these two puzzle areas exist separately within the game world, we’ve consolidated both solutions in this comprehensive guide for efficiency:
- The Lethe Ministry of Cultural Primacy unlocks during Act 2’s early stages after your conversation with Tania inside the APC mobile base.
- The Lethe National Library becomes available later once you’ve completed your discussion with Abbot Jaffer at Pathem Abbey.
Pro Tip: These indoor puzzle zones differ significantly from open-world challenges. The confined spaces mean you’ll encounter more concentrated enemy encounters and limited escape routes, requiring tactical positioning during combat sequences.
When approaching the Lethe Ministry Puzzle, your journey begins at the underground parking facility. Ascend the main stairwell to reach the uppermost level where the administrative offices are located. Upon entering Marston Ral’s office, you’ll discover the grim scene of his execution by hanging from the ceiling beams.
Conduct a meticulous examination of the room’s distinctive features and the entire floor’s layout. Pay particular attention to the portraits depicting King Aster, the vintage radio positioned adjacent to the royal painting, and Ral’s personal computer workstation.
Thoroughly explore the top floor while interacting with surviving resistance fighters. In one of the side chambers, you’ll encounter Maeve Tristana, a terrified woman trapped by fear. She refuses to evacuate until you eliminate the spectral Hollow entity patrolling the hallway. Here’s your action plan:
- Navigate to the corridor where the Hollow manifests, then descend through the collapsed flooring section to access the sub-level areas.
- Engage and defeat the hostile forces occupying the expansive office space below, then retrieve Marston Ral’s leather wallet from his desk.




Common Mistake: Many players rush to combat without fully documenting the environmental clues. The password solution requires correlating information from multiple sources: the painting dates, radio frequency numbers, and computer login attempts. Document everything before proceeding to the lower level.
Advanced Strategy: Use stealth takedowns on the lower floor rather than direct confrontation. The office space contains multiple cover points that allow you to isolate and eliminate enemies systematically without alerting the entire area.
The Lethe National Library presents a completely different puzzle dynamic focused on academic research and historical restoration. Unlike the Ministry’s political themes, this location emphasizes literary preservation and archival knowledge.
Begin your investigation in the Computer Room where you’ll encounter Iblis, who provides crucial background context. Then proceed to Embry Hall, where the book-based puzzles require careful examination of specific volumes and their placement.
The final stage involves the Book Restoration chamber, where you must decipher the passcode by analyzing damaged manuscripts and reconstructing missing information from surrounding clues.




Time Management Tip: Allocate approximately 25-30 minutes for the Library puzzle sequence. The book restoration phase alone can consume 10-15 minutes if you don’t systematically approach the clue hierarchy.
Optimization Strategy: Before engaging with Iblis, scout the entire Computer Room for additional documents that provide context clues for later stages. Many players miss the secondary documents that make the Embry Hall book placements more intuitive.
Success in these puzzle sections requires more than just following steps—it demands understanding the game’s environmental storytelling mechanics. The developers have woven clues into every aspect of these locations, from visual elements to audio recordings.
Combat Optimization: The confined spaces of both locations favor close-quarters weapons and quick evasion tactics. Equip gear that enhances mobility rather than heavy armor, as you’ll need to navigate tight corridors and collapsed structures.
Clue Interpretation Mastery: Learn to recognize pattern relationships between seemingly disconnected elements. The painting dates in the Ministry often correlate with historical events mentioned in documents found elsewhere in the building.
Resource Management: These puzzle areas typically don’t require extensive ammunition, but you should conserve healing items for unexpected enemy encounters.
Common Pitfalls to Avoid:
- Rushing through environmental examination phases
- Ignoring secondary NPC dialogues that contain hint information
- Failing to document clue sequences before attempting password inputs
- Underestimating the tactical advantage of stealth approaches in library sections
