Welcome to Thriller, a tabletop roleplaying game designed to immerse you in modern horror scenarios limited only by your imagination. Whether facing off against supernatural threats, delving into sinister mysteries, or surviving deadly encounters, your choices and creativity define your story. In Thriller, every decision can lead to triumph or tragedy, testing your courage, ingenuity, and sanity.

What You Need

Before starting your first session, gather the essential materials:

• Polyhedral Dice Set: One each of d4, d6, d8, d10, d12, d20, and a pair of d10 for percentile rolls (d100). These dice determine the outcomes of your actions and the twists of fate in your story.
• Character Sheets: Printed or digital sheets to record your character’s abilities, stats, equipment, and background details.
• Pencils and Paper: Essential for taking notes, sketching maps, and tracking resources or initiative order during gameplay.

Optional items to enhance gameplay:

• Maps and Grid Paper: Visual aids for navigating encounters or plotting your investigations.
• Tokens or Miniatures: Represent characters and adversaries, making tactical situations clearer.

Playing the Game

Thriller is a collaborative storytelling game guided by a Game Master (GM), who creates and narrates the scenarios, controlling the environment, non-player characters (NPCs), and monsters. Other participants play as characters (PCs), defining their actions and responses to unfolding events.

Roles in the Game

Players:

• Create and roleplay characters with unique strengths, skills, and backgrounds.
• Describe actions and decisions; roll dice to resolve uncertain or risky situations.
• Work together, leveraging each character’s abilities and resources to survive.

Game Master (GM):

• Narrates scenarios, controls NPCs, and sets challenges.
• Maintains the pacing, suspense, and fairness of the game.
• Adjudicates rules and outcomes based on dice rolls and player decisions.

How Gameplay Works

Gameplay in Thriller progresses through narrative scenes:

1. Narration: The GM describes the setting, environment, and immediate threats or opportunities.
2. Player Actions: Players describe what their characters do, from investigating clues to engaging threats or interacting with NPCs.
3. Dice Rolls: When actions have uncertain outcomes, players roll dice (typically a d20 plus modifiers from attributes or skills) against a Difficulty Class (DC) set by the GM.
4. Resolving Outcomes: The GM interprets dice rolls, narrating successes, failures, and complications that advance the story.

Campaigns and One-Shots

Thriller can be played in short, intense one-shot sessions ideal for introducing new players or exploring a standalone mystery, or as extended campaigns that allow character growth, recurring threats, and complex storylines. Choose the format that fits your group’s preferences and play style.

The Most Important Rule

Above all, Thriller is about creating memorable experiences tailored specifically to your group’s tastes. Homebrewing, modifying or creating rules, is strongly encouraged to ensure the best experience for everyone involved. Adapt rules, scenarios, and mechanics to your preferences and storytelling goals. The ultimate aim is enjoyment and immersive storytelling, so don’t hesitate to customize Thriller to perfectly fit your group’s unique playstyle. Remember, the core of Thriller is storytelling and collaborative excitement. Gather your friends, embrace the darkness, and enjoy crafting memorable horror tales together.
