Learn how to seamlessly integrate the Grom & Thalia expansion into your Zombicide: Black Plague games. Step-by-step instructions for setup and gameplay.

Quick answer

To add Grom & Thalia to your Zombicide: Black Plague game, simply place their miniatures on the board, use their unique survivor cards, and follow the standard survivor rules with no special expansion modules required.

What the expansion includes and what it doesn't

The Grom & Thalia expansion is a Kickstarter exclusive that adds two new survivor miniatures and their corresponding survivor cards. It does not include new scenarios, tiles, or zombie types. You'll need the Zombicide: Black Plague core game to play. The expansion is designed to plug directly into any existing game session without additional rules.

Why you might want to add them

Grom and Thalia offer fresh tactical options. Grom is a melee-focused survivor, while Thalia brings ranged combat skills. Adding them lets you experiment with new team compositions, especially in larger games with 4-6 players. The expansion is lightweight and quick to integrate, making it ideal for players who want variety without learning new systems.

How to add Grom & Thalia to your game

1. Unpack and organize the components: Open the expansion box and remove the two miniatures and the two survivor cards. Check that the miniatures match the art on the cards. No assembly is required. Common mistake: Assuming the expansion includes dice or tokens. It does not—use components from the core game.
2. Choose which survivor(s) to add: Decide whether to add Grom, Thalia, or both. They are independent survivors; you can use one or both in the same game. Each player controls one survivor. Checkpoint: If you add both, ensure your group has enough survivor slots (max 6 survivors total).
3. Set up the survivor cards and miniatures: Place the chosen survivor card(s) in front of the controlling player. Put the corresponding miniature on the starting zone of the first tile as per the core game rules. No additional setup steps are needed. Common mistake: Forgetting to shuffle the new cards into the survivor deck if you draw randomly. If you're hand-picking, just place them directly.
4. Play using standard survivor rules: Grom and Thalia follow all standard Zombicide: Black Plague survivor rules: they have the same action types, experience levels, and equipment slots. Use their unique abilities as printed on their cards. Checkpoint: Their abilities may differ from core survivors—read the cards aloud to the group before the first turn to avoid confusion.
5. Integrate into any scenario: You can use Grom and Thalia in any official or custom scenario from the core game. They do not require a special expansion scenario. Simply replace or add them to the survivor pool. Common mistake: Thinking the expansion adds new objectives or rules. It does not—treat them as regular survivors.
