Reality Stability Office: Complete Strategy Guide & Walkthrough

Overview

Reality Stability Office is a dystopian anomaly-detection sim from Nyrel Design, released June 20, 2026 on Steam. You play as a checkpoint inspector at the last stable city's border. Your job: examine arrivals, verify documents, cross-reference data, and decide who is real enough to enter. Unlike other inspection games, the systems you rely on are actively unreliable. Documents glitch mid-read. The database contradicts itself. Your own perception degrades over time.

The game costs $7.29, runs 4–6 hours per playthrough, and has 28 Steam achievements across multiple endings. It's mouse-only, single-player, and plays like a psychological horror take on Papers, Please with a sanity system that makes every decision feel consequential.

Who this guide is for: Players who've done their first shift and want to understand the deeper mechanics — how the sanity system works under the hood, how to spot every anomaly type, how to reach specific endings, and how to optimize each shift for maximum accuracy with minimum sanity loss.

Getting Started: Your First Shift

Before You Start

1. Set the difficulty to Normal. Easy mode makes anomalies too obvious — you won't learn proper detection skills. Hard mode is punishing until you know the system.
2. Read the briefing. Every shift starts with a briefing. It tells you the day's threat level, known anomaly types in the area, and any special instructions. Skipping it costs you.
3. Save manually. The game has no autosave between arrivals. Save every 3–4 arrivals. The first time you lose 30 minutes of progress to a sanity crash, you'll learn why.

The Inspection Loop (Abbreviated)

Complete arrival → Collect docs → Cross-reference terminal → Visual scan → Interrogate → Decide → Next arrival

Core Mechanics (Deep Dive)

The Sanity System

Sanity is a resource that starts at 100% each day and depletes based on your actions:

Sanity thresholds and their effects:

The sanity recovery trick: Making 3 correct decisions in a row triggers a hidden +5% sanity bonus. Stack your easy cases (obviously real, obviously anomalous) early in the shift to build this buffer before tackling the ambiguous ones.

Document Verification

Each arrival presents 3–5 documents. Cross-reference each against the database:

Identity Card:

• Check photo match (face shape, eye color, scars, hair)
• Verify ID number in terminal (does it exist? expired? reported stolen?)
• Check issuing authority seal (genuine seal has micro-text at the border)
• Expiration date (must be current or future)

Travel Permit:

• Origin city (does it exist in the database? is it under quarantine?)
• Permit validity dates (entry and exit)
• Route stamps (do the stamps form a logical path?)
• Special endorsement codes (cross-reference with daily briefing)

Health Declaration:

• Vaccination status (check against recent outbreak zones)
• Anomaly exposure history (truthful answer shows hesitation patterns)
• Signature (compare with ID card signature)

Employment Letter:

• Employer name (exists in database?)
• Position (realistic for the person's age/background?)
• Salary (proportional to position? Or suspiciously high/low?)

Family Registry:

• Names + relationships (consistent with other docs?)
• Address consistency (same district as travel permit origin?)
• Recent changes (new additions or removals flagged?)

Tool Usage Guide

Tool reliability scales with your sanity. At 100–70%, tools are 90% accurate. At 69–40%, 70% accurate. Below 40%, tools can give false readings. Don't trust the X-Ray when you're hallucinating.

Anomaly Detection Guide

Photo Distortion

The most common anomaly. The photo changes when you look away and back.

Detection method: Look at the photo, look at any other document, then look back. If the photo changed, it's an anomaly.

Variations:

• Eye color shift (brown ↔ blue) — subtle, easy to miss
• Hair length/style change — medium difficulty
• Full face replacement — obvious, but rare
• Photo becomes static/no animation — the arrival isn't breathing in the photo

False positive: Low sanity can make a normal photo appear to shift. If sanity < 40%, ask a colleague (hover over "Request Second Opinion" for 2 seconds — this option appears at low sanity only).

Document Corruption

Text on documents flickers, changes, or appears in multiple fonts.

Detection method: Open a document, read it, close it, reopen it. If the text changed, it's corrupted. Corrupted documents don't always mean the arrival is anomalous — sometimes the document itself is just damaged. But a corrupted document always warrants extra scrutiny.

Key tells:

• Dates that change between readings
• Names that appear in different fonts
• ID numbers with digits that swap positions
• Seals that flicker between authentic and fake

Behavioral Irregularity

The arrival's movements are off. They might be looping an animation, repeating phrases, or showing no expression change.

Detection method: Watch the arrival for 5 seconds before starting document check. A real person will perform small idle animations: blinking, shifting weight, looking around. An anomaly will either do nothing (static) or repeat the exact same movement cycle.

Audio tells:

• Repeating the same phrase verbatim when asked different questions
• Voice that sounds slightly delayed (synced wrong with mouth)
• Laughing or crying at inappropriate moments
• Answering before you finish the question

Database Mismatch

The terminal shows contradictory information.

Detection method: Check each document field against the terminal one at a time. If the terminal shows the person existing in two places at once, or if the ID number belongs to a different name, you have a database mismatch.

Database mismatches are always anomalies. Unlike document corruption, a database mismatch is definitive proof. If the terminal says "This ID belongs to [different person]", the arrival is not who they claim to be.

Memory Inconsistency

The arrival's story changes under repeated questioning.

Detection method: Ask all available questions. Then ask one question again. If the answer differs — different destination, different reason for travel, different employment — the arrival is anomalous.

Best practice: Always ask "What is your destination?" last. This is the question people/anomalies most often contradict themselves on.

Environmental Glitch

The booth itself glitches. The terminal flickers. The arrival's shadow moves wrong.

Detection method: These are visible without any action. If you see the booth flickering, the terminal showing garbled text, or the arrival's shadow moving independently of them, note it. Environmental glitches are the game telling you that reality is breaking down. They always accompany the arrival being anomalous, but can also happen from low sanity alone.

Step-by-Step Shift Walkthrough

Optimal Inspection Protocol (Every Arrival)

1. 10s — Observe arrival (watch for behavioral tells before they know you're watching)
2. 15s — Briefing check (does this arrival match any known anomaly type described today?)
3. 20s — Collect and scan documents (open each one, look for corruption)
4. 30s — Terminal cross-reference (check every document field against database)
5. 20s — Photo verification (look once, look away, look back)
6. 15s — Interrogation (ask all questions, then repeat the destination question)
7. 10s — Tool use if needed (X-Ray for physical suspicion, Phone for behavioral)
8. 5s — Decision (stamp and move on)

Total: ~2 minutes per arrival. Don't rush. Each incorrect decision costs more time in reloaded saves than taking 2 minutes per case.

Decision Matrix

Golden rule: If 2+ indicators are anomalous, deny. If 1 indicator is anomalous but ambiguous, interrogate more. If 0 indicators are anomalous, approve.

Ending Guide

Your decisions determine which ending you reach. There are 7 confirmed endings:

End-Specific Strategies

The Good Ending: Prioritize accuracy over speed. Save after every 3 correct decisions. Never use tools unnecessarily. Read the briefing every day. If your sanity drops below 50%, save and take a break (the game offers rest prompts). The Good Ending requires you to spot the story-critical clues too — pay attention to recurring names and document patterns.

The Truth Seeker: This requires 2 playthroughs minimum. On the first run, don't worry about accuracy — just explore every dialogue option, use every tool, and note which document names appear repeatedly. On the second run, follow the clues. The key is a character named "Valerie K." who appears in multiple documents across different arrivals.

The Anomaly Ending: This is the easiest ending to get deliberately. Just reverse your decisions: admit anyone who shows anomaly signs, deny anyone who seems normal. Your sanity will crash, which is part of the ending narrative.

Advanced Tips

1. The Terminal Lie Pattern. The database has a predictable corruption cycle. Data entered before 9:00 AM in-game time is more reliable than data entered after 3:00 PM. If facing an ambiguous case, prioritize documents collected in the morning.

2. Colleague Requests. At sanity < 40%, a "Request Second Opinion" button appears in the bottom right. Your colleague has a 70% accuracy rate. Use it as a tiebreaker, not a primary tool.

3. Skip the phone verification on obvious cases. Phone verification costs 2% sanity. If the documents, photo, and behavior all align, you don't need it. Reserve tools for ambiguous cases.

4. The 3-Correct Streak Bonus. As mentioned, 3 correct decisions in a row grants +5% sanity recovery. Stack easy cases early. If you make a mistake, follow it with your next easiest case to rebuild the streak.

5. Document order matters. Always check documents in the same order: ID → Travel Permit → Health → Employment → Family Registry. This builds muscle memory and reduces the chance of missing a check.

6. The Mirror Test. If you're unsure about photo distortion, look at your own reflection in the scanner glass (a small visual detail in the game). The reflection stays stable. If the photo shifts but your reflection doesn't, trust your reflection.

7. Interrogation tells by voice. The game uses different voice actors for anomalies vs real humans. Anomalies have a slightly metallic or hollow resonance in their voice. Play with headphones — this is subtle but consistent.

8. The hidden "skip dialogue" penalty. Spamming spacebar to skip arrival dialogue skips important behavioral tells. The arrival's first line of dialogue contains the most behavioral data. Never skip the first exchange.

9. Saving before difficult arrivals. If the briefing mentions a "high-value target" or "known anomaly on the move," save before that arrival. These story-critical arrivals have the most complex anomalies.

10. The final shift is always rigged. The last shift of the game contains 1–2 arrivals that are designed to be impossible to correctly judge. The game forces a moral choice. Don't beat yourself up about getting it wrong — it's part of the narrative.

FAQ / Common Mistakes

Q: Why did my game end on day 4 when I still had sanity? A: The game has a fixed length of 7–10 in-game days (varies by playthrough). You didn't die — the story ended. Start a new game for a different outcome.

Q: Is it better to deny everyone to be safe? A: No. Denying real humans costs 10% sanity each. A paranoid playthrough ends with a sanity crash faster than a permissive one.

Q: How do I unlock the X-Ray scanner? A: It's available from day 1. Click the scanner icon (circle with crosshairs) in the bottom toolbar. It costs 2% sanity per use.

Q: What does the green highlight on documents mean? A: Green highlight means the terminal verified that specific field as matching its database. BUT — the database can be corrupted. Green doesn't guarantee truth, it only guarantees the database agrees with the document.

Q: Why did the arrival's face change after I used the X-Ray? A: The X-Ray can trigger a visual anomaly response. If you see a face change after scanning, it's a confirmed anomaly — the arrival is reactive to inspection tools.

Q: Can I replay specific days? A: No. The game saves your full playthrough state. To try different decisions, you need to load a manual save from before that arrival, or start a new game.

Q: How long does a full playthrough take? A: 4–6 hours for one ending. 10–15 hours for all achievements (multiple playthroughs).

Q: Is there a penalty for taking too long on one arrival? A: No time pressure per arrival. Take as long as you need. The only time-related element is the daily briefing expiring (it disappears after your first stamp of the day).
