Citizen Sleeper is a dice-driven role-playing game developed by indie studio Jump Over the Age and published by Fellow Traveller. First released on May 5, 2022 for PC and later on PlayStation 4/5 in March 2023, it also supports Xbox One, Xbox Series X/S, and Nintendo Switch. You assume the role of a “Sleeper,” a digitized consciousness in a robotic body, striving to survive indenture on the lawless orbital bunker called the Eye.

2. Story & Setting
You play as a “Sleeper,” a human consciousness digitized and implanted into a synthetic body owned by the Essen‑Arp corporation. So, after escaping from indentured servitude, you find yourself stranded on Erlin’s Eye, a deteriorating space station governed by rival factions and filled with outcasts. Resources are scarce, your body is decaying, and without stabilizer serum you risk breakdown as you scramble to survive through daily dice-based actions.

On the station, you navigate relationships and quests known as Drives, connecting with characters such as foster‑families, communal workers, and union members. These branching storylines influence your fate and contribute to one of several possible endings. Your decisions, from forging medicine for a friend to building a colony ship, ripple through the station’s society and shape where your journey eventually leads.

3. Core Mechanics & Dice System
Each cycle you receive a number of dice equal to your current Condition (health). Dice range from 1–6:
- 1–2: 50% Neutral/50% Negative,
- 3–4: 25% Positive/50% Neutral/25% Negative,
- 5: 50% Positive/50% Neutral,
- 6: 100% Positive

You assign dice to tasks across five categories, i.e. Engage, Interface, Endure, Engineer, and Intuit, with each tied to NPC drives, side activities, or station maintenance.
Task outcomes influence resources or story: a Positive result grants bonuses (credits, items, drive progress), Neutral has mixed effects, and Negative can cost Condition, Cryo (stabilizer), or skip drive clocks entirely. Managing which die goes where is the strategic heart of the game.

4. Resource & Condition Management
Condition acts as both health and dice budget. It depletes on Negative DANGER outcomes and when you fail to stabilize. Cryo points (stabilizer currency) are required to restore Condition, e.g. Sabine the slum doctor gives one free dose, but thereafter each Stabilizer costs 100 cryo. Energy (food) prevents Condition loss when out of stabilizer, so combine fungus, water, or chicken meat into Nutrition Packages to restore HP and stave off fatigue.

Cryo also buys fuel for the distillery run, upgrades at the Rig base, and occasional dice repairs. Inventory space is limited: scrap unused items and choose between storing extra stabilizers or stocking rations based on upcoming drive requirements.

5. NPC Questlines & Endings
Citizen Sleeper features eleven main “drives,” each tied to an NPC whose storyline can end in positive, neutral, or fatal outcomes. So, completing these drives in specific orders unlocks nine distinct endings and 27 achievements.

| NPC | Role | Primary Skill | Possible Endings |
|---|---|---|---|
| Dragos | Salvager | Engineer | Survival Route / Loss |
| Sabine | Slum Doctor | Endure | Medical Unity / Abandonment |
| Emphis | Food Vendor | Endure | Feast Finale / Collapse |
| Feng | Engineer | Engineer | Workshop Peace / Shutdown |
| Tala | Distiller | Interface | Fuel Freedom / Surrender |
| Lem & Mina | Shipyard Workers | Engage | Gateway Escape / Stuck |
| Ethan | Bounty Hunter | Intuit | Hunter’s Justice / Betrayal |
| Ankhita | Mercenary | Engage | Mercenary’s Vendetta / Truce |
| Riko | Botanist | Intuit | Floral Utopia / Wilting |
| NeoVend | Vending AI | Interface | Machine Revolution / Shutdown |
| Bliss | Mechanic | Engineer | Rig Revival / Rust |
6. Advanced Strategies & Pro Tips
Veteran Sleepers refine their runs with these high-level insights:

- Fix Negatives Early: Spend one upgrade point to remove any –1 penalty in your starting stats (e.g. Interface, Endure, Engineer, Intuit, Engage) to avoid bad rolls in key drives.
- Predictive Reasoning: Unlocks on the Intuit tree; reveals all potential drive outcomes before committing dice, letting you optimize risk vs. reward.
- Photosynthetic Skin: Endure-tree perk that lets you recover energy at the Rig by “sunbathing,” reducing Cryo spent on food.
- Instant Karma: Final Intuit perk grants one free re-roll per cycle, vital for clutch success on high-risk tasks like Bounty Hunter or Mercenary drives.
- Dice Preservation: Use low dice on SAFE tasks (e.g., Noodle stand shifts) to preserve mid/high dice for DANGER actions like factory sabotage or data heists.

7. Conclusion
This guide has clarified Citizen Sleeper’s core systems, from cycle-based dice allocation and resource loops to NPC drives and missable endings. So, by following these strategies, you’ll avoid common pitfalls, manage your Condition and Cryo effectively, and navigate every questline to unlock all nine endings and 27 achievements.

Start your next run by fixing any negative stat, unlocking Predictive Reasoning, then tackle Dragos’s and Sabine’s drives in the first three cycles with optimized dice assignments. So, record outcomes and adjust your approach to secure each ending in a single playthrough.
