Unlocking all 20 endings in Fu Sha 3: Night Clinic requires navigating a complex web of choices primarily revolving around three key factors: your relationship with Dr. Evelyn Reed, your allegiance to the An-Ding Corporation, and your handling of the 'Marrow Key' artifact in the final chapter. This guide breaks down every single outcome, from the bleakest failures to the game's true resolution.
The Core Pillars: What Determines Your Fate?
Your path through the derelict An-Ding facility isn't determined by a single dialogue choice, but by the cumulative weight of your actions. Three hidden metrics are constantly being tracked, and their final state dictates which ending you receive. Understanding these is the first step to mastering the narrative.
- Evelyn's Trust: This score measures your rapport with Dr. Reed. It increases when you support her, share resources, defend her, and trust her with critical information. A high score is essential for her best endings and the True Ending.
- An-Ding Loyalty: This tracks how closely you follow corporate protocol and the directives of the facility's automated system. Completing objectives, submitting data logs, and eliminating threats in a 'by-the-book' manner will raise this score.
- The Marrow Key Decision: In the final act, you will acquire the Marrow Key, a device capable of stabilizing the facility's core or destroying it. Who you choose to give this key to—or if you use it yourself—is the final, pivotal choice that locks you into a specific branch of endings.
The An-Ding Corporation Endings (Endings 1-7)
These endings are the result of prioritizing corporate objectives and maintaining a high An-Ding Loyalty score. Your relationship with Dr. Reed is secondary, and often, you'll be forced to act against her interests to achieve these outcomes.
Corporate Loyalist Path
These are for players who follow orders to the letter. You must consistently submit data logs to the An-Ding network, eliminate non-compliant personnel (including other survivors), and hand the Marrow Key over to the An-Ding retrieval team at the end.
| Ending Name | Ending Number | Key Requirements |
|---|---|---|
| The CEO's Right Hand | 1 | High Loyalty, High Evelyn's Trust. Persuade Evelyn to surrender with you. |
| Project Nightingale | 2 | High Loyalty, Low Evelyn's Trust. Subdue Evelyn and deliver her and the key to An-Ding. |
| Containment | 3 | High Loyalty. Use the Marrow Key on the facility core as ordered, sacrificing everyone inside. |
The Betrayal Path
A high loyalty score doesn't always mean a happy ending with the company. These endings occur when you follow An-Ding's orders for most of the game but make a critical deviation at the last moment, often for personal gain.

- Ending 4: A New Asset: Requires high loyalty throughout, but you must use the Marrow Key on yourself in the final room. An-Ding contains you as a valuable but volatile new specimen.
- Ending 5: Rogue Element: Maintain high loyalty, but refuse to hand over the key to the retrieval team. You are hunted down and eliminated in the epilogue.
- Ending 6: Loose End: Keep your loyalty score moderate by completing some objectives but concealing others (like the existence of the secondary lab). An-Ding decides you know too much and eliminates you before you can extract.
- Ending 7: The Whistleblower: This complex ending requires collecting all four pieces of incriminating evidence against the project lead, Director Chen. You must maintain high loyalty until the very end, then transmit the evidence using the emergency broadcast terminal before handing over the key. You are extracted, but the corporation is thrown into chaos.
Dr. Evelyn Reed's Endings (Endings 8-14)
These outcomes are tied directly to achieving a high Evelyn's Trust score. You must consistently side with her, share your limited medical supplies, defend her from a corporate assassin in Chapter 4, and ultimately entrust her with the Marrow Key. Your An-Ding Loyalty score should be low or moderate.
Alliance Path
Building a strong bond with Dr. Reed opens up paths focused on mutual survival and escape, far from the grasp of the An-Ding Corporation. The key to this path is a series of four unmissable trust-building events: sharing your rations in Chapter 2, defending her from the An-Ding agent, revealing the truth about your past when prompted in the medical bay, and trusting her with the lab key instead of opening it yourself.

- Ending 8: A Future Together: Maximum Evelyn's Trust. Give her the Marrow Key and choose the dialogue option about escaping together. You both make it out of the city limits.
- Ending 9: The Cure: High Trust. Give her the key and encourage her to use it to synthesize a cure from the core's energy. She succeeds, but the process is fatal for her. You escape with the cure.
- Ending 10: Exodus: High Trust, and you must have also saved at least two of the other trapped scientists. You and the group of survivors escape, led by Evelyn.
- Ending 11: Shared Burden: High Trust, but you must have been infected during the Chapter 5 boss fight. Evelyn uses the key to put you into cryo-stasis, vowing to find a cure for your condition.
Antagonist Path
If you actively work against Evelyn, lie to her, or betray her, your relationship will sour, leading to these grim outcomes.
- Ending 12: A Necessary Sacrifice: Low Evelyn's Trust. You give her the Marrow Key, but she betrays you, locking you in the core room to die so she can escape alone.
- Ending 13: Doctor's Orders: Low Trust. You refuse to give her the key, leading to a final confrontation where you are forced to kill her.
- Ending 14: Unforgivable: This requires a specific action. After building high trust, you must choose to shoot her during the standoff with the An-Ding retrieval team. This is considered the most nihilistic ending.
Independent & 'Bad' Endings (Endings 15-19)
These endings are generally triggered by specific, isolated actions, failures, or by ignoring the main narrative threads entirely. They are often abrupt and serve as cautionary tales for careless players.

- Ending 15: Left Behind: Fail to reach the extraction point in the final chapter before the 15-minute countdown expires. The clinic self-destructs with you inside.
- Ending 16: Subject Zero: In the Director's Office, find the 'corrupted sample' in the wall safe. Instead of using it for research, choose the option to inject it into yourself. You transform into one of the game's monsters.
- Ending 17: The Easy Way Out: Find the antique single-shot derringer in the locked case on the Director's desk. At any point afterward, you can use it on yourself from the inventory menu.
- Ending 18: Silent Witness: After your initial meeting, it's possible to avoid all mandatory conversations with Dr. Reed by using vents and alternate routes. If you reach the end of the game without strengthening your bond, you get a unique ending where you escape alone, leaving her fate unknown.
- Ending 19: Empty-Handed: Give the Marrow Key to the wrong person. If you give it to the seemingly harmless janitor, he reveals himself to be an agent for a rival corporation and eliminates you.
How to Get the True Ending (Ending 20: "Symbiosis")
This is the canonical, most difficult, and most rewarding ending in Fu Sha 3: Night Clinic. It requires a specific sequence of actions and a deep understanding of the game's lore and crafting systems. It represents a third path that rejects both An-Ding's control and Evelyn's desperate escape.
Follow these steps precisely:
- Achieve Maximum Evelyn's Trust: You must successfully complete all four key trust-building events mentioned earlier.
- Sabotage An-Ding: Keep your An-Ding Loyalty score below 25%. You can do this by feeding false data into terminals, letting test subjects escape, and generally defying the automated system's directives.
- Collect All Three Researcher's Notes: These hidden collectibles explain the true nature of the outbreak and hint at a third solution. They are found in the morgue, the data server room, and the hidden passage behind the director's bookshelf.
- Craft the Synthesized Cure: You must acquire the 'corrupted sample' from the Director's safe and the 'stabilizing agent' from the cryogenics lab. Combine them at a research station to create the unique 'Synthesized Cure' item.
- Make the Third Choice: In the final confrontation, both Evelyn and the An-Ding team will demand the item in your possession. Ignore both of them. Walk to the central containment unit in the middle of the room and use the 'Synthesized Cure' on it. This pacifies the entity within, ends the outbreak at its source, and saves the entire facility.

Frequently Asked Questions
Can you get multiple endings in one playthrough? No, each playthrough results in one of the 20 endings. However, you can use the game's chapter select or make strategic manual saves before major decision points (like giving away the Marrow Key) to explore different branches without replaying the entire 8-hour campaign.
What's the hardest ending to get? The True Ending, "Symbiosis," is the most complex due to its specific sequence of item collection, crafting, and dual-sided relationship management. Following that, "The Whistleblower" (Ending 7) is also difficult, as it requires maintaining high An-Ding loyalty before executing a very specific and time-sensitive betrayal.
Does the starting background choice affect the endings? Your starting background ("Ex-Corporate Security," "Field Medic," or "Researcher") provides a slight starting bonus to one of the core metrics. "Ex-Corporate Security" gives a small boost to An-Ding Loyalty, while "Field Medic" gives a head start on Evelyn's Trust. These starting points are easily overridden by your in-game actions and do not lock you out of any endings.
The Final Diagnosis
With 20 possible fates, Fu Sha 3: Night Clinic is a game that demands multiple playthroughs to fully appreciate its branching narrative. The key isn't just one big decision, but the cumulative weight of your loyalty, your trust, and your willingness to look for a third option beyond the obvious choices presented to you. Whether you become a corporate tool, a desperate survivor, or the facility's savior is entirely in your hands.
