Starting the quest transports you to a bizarre, toy-like realm controlled by Chuckles. Your goal is to beat him at Russian Roulette, but the game is fixed in his favor. To win, follow these steps carefully:

1. Don't Play Immediately – Engaging Chuckles in the game right away will result in certain failure due to the rigged setup.​

2. Use Spacetime Vision – Press ‘Q’ to activate Spacetime Vision. This will reveal a cable running from the roulette table to a hidden spot.

3. Follow the Cable – Trace the glowing cable to a wall. Behind it, you'll find another Chuckles-looking figure manipulating the game.

4. Ask for a Break – Go back to the original Chuckles and choose the dialogue option saying you need air. This will make him unlock a nearby door, giving you access to the area behind the wall.

5. Take Down the Cheater – Go through the unlocked door and find the room where the second Chuckles operates the cheating device. Guns don't work here, so equip a melee weapon. Sneak up and eliminate him.

6. Disable the Device – After defeating the second Chuckles, interact with the Roulette Cheating Device to turn it off, ensuring a fair game.

7. Face Chuckles Again – Return to the main area and accept Chuckles' challenge once more. This time, choose to pull the trigger yourself. With the cheater gone, the game will work in your favor, leading to Chuckles' defeat.
