In this section, you will face the final encounter against The Psychiatrist. This sequence begins after you have collected the last Ghost and progresses through multiple chase and combat phases involving both Low and Alone.

The Chase

After obtaining the last Ghost, proceed forward until a cutscene triggers, showing the return of The Psychiatrist. Once the scene ends and you regain control, start running immediately in Little Nightmares III.

The boss will pursue you through several corridors, requiring quick navigation and timing to avoid being caught. Continue until you fall into a large room containing a Gong.

Once inside the room, take control of Alone and run directly to the Gong. Strike it to drive The Psychiatrist away temporarily. As soon as she hits the Gong, move quickly to the right side of the room. Staying in place will result in being crushed by debris. Keep running until you reach a Mirror that alone refuses to enter in Little Nightmares III.

Surviving The Second Attack

After Alone hesitates at the Mirror, the Psychiatrist will grab it and begin another round of attacks. Debris will start falling, and you must keep moving to avoid being hit. Eventually, a second Gong will drop into the area.

Clear the planks blocking it and strike the Gong once again. This action will trigger The Hand to attempt to crush you. When this happens, switch to Low and shoot an arrow directly at the Hand’s Eye in Little Nightmares III.

The sequence will repeat a second time. Another Gong will fall, requiring Alone to strike it while Low targets the Eye again. If you are not controlling Low, call for him to act when the Eye becomes visible. Once both characters complete their actions, the Psychiatrist’s head will fall forward, revealing cracked glasses on one side.

Destroying The Glasses

Take control of Alone and move toward the head. Use her wrench to strike the cracked side of the Glasses, breaking them. Immediately afterward, Low must fire one final arrow into the Eye on the Face itself. This will end the encounter and trigger a final cutscene.

The Final Sequence

Following the boss’s defeat, a scene will play showing Low and Alone falling before Low awakens inside his cell. It is revealed that Alone is actually a doll that Low has depended on. Afterward, both characters awaken near the last Mirror in Little Nightmares III.

Approach it, and Low will reach out to take Alone’s hand to pass through. She will resist, but Low will pull her in regardless. The Mirror will reject Alone, throwing her back out and shattering in the process. Alone will then vanish, marking the end of Little Nightmares 3.

You can wait after the credits for a brief bonus scene that concludes the story in Little Nightmares III.
