Once you initiate the quest, you'll be transported to a whimsical, toy-like dimension ruled by Chuckles. Your main goal is to defeat him in a game of Russian Roulette, which is rigged in his favor. To outwit him, follow these steps:

  1. Avoid Immediate Engagement: Resist the urge to engage in the game immediately, as this will lead to certain defeat due to the rigged setup.
  2. Activate Spacetime Vision: Use the 'Q' key to activate your Spacetime Vision, which will reveal a cable connected to the roulette table, leading to a hidden area.
  3. Trace the Cable: Follow the highlighted cable to a wall where you'll find another figure resembling Chuckles manipulating the game.
  4. Request a Break: Return to Chuckles and choose the dialogue option asking for some fresh air. This will unlock a nearby door, allowing access to the area behind the wall.
  5. Confront the Deceptive Clown: Proceed through the unlocked door to the room where the second Chuckles operates the cheating mechanism. Since firearms are disabled in this dimension, arm yourself with a melee weapon, approach stealthily, and take him down.
  6. Disable the Cheating Device: After neutralizing the second Chuckles, interact with the Roulette Cheating Device to deactivate it, leveling the playing field.
  7. Challenge Chuckles Again: Return to the main area and accept Chuckles' challenge once more. Opt to pull the trigger yourself. With the cheating mechanism disabled, the game will now favor you, leading to Chuckles' defeat.
