Mouse Guard Roleplaying Game Box Set – 2nd Edition

The Territories are dangerous. Good thing the Guard is small but mighty.

Enter the world of Mouse Guard with this complete 2nd Edition Roleplaying Game Box Set, based on the beloved world created by David Petersen.

Players become members of the Mouse Guard, forming patrols and taking on missions throughout the Territories—protecting settlements, traveling dangerous paths, helping mice in need, and facing a world where weather, wilderness, predators, and difficult choices can all become formidable adversaries.

This boxed edition of the Origins Award-winning roleplaying game brings together the rules and play materials you need to gather a patrol and begin your own adventures in the world of the Guard.

Join the Mouse Guard

The mice of the Territories live in a world much larger and more dangerous than they are.

The Guard serves as protector, pathfinder, guide, and peacekeeper, helping connect far-flung settlements and responding when something threatens the lives of the mice who call them home.

As players, you'll form a patrol of Guardmice and head out on missions together.

Sometimes that means confronting an immediate danger.

Sometimes it means surviving the journey there.

Adventure in David Petersen's World

Mouse Guard turns the richly imagined setting of David Petersen's comics into a world built for collaborative storytelling.

Create your own members of the Guard, develop their strengths and relationships, and discover what happens when duty meets a world that doesn't particularly care how small you are.

The game gives players and Game Masters the tools to create new stories within the Territories rather than simply replaying adventures from the comics.

Why We Love It

The scale changes everything. A journey that would be ordinary for a human becomes an expedition when you're a mouse.

You're part of something. Characters aren't simply wandering adventurers—they belong to the Guard, with responsibilities, relationships, and mice depending on them.

David Petersen's world was made for storytelling. The Territories are beautiful, dangerous, and filled with places where another patrol's story could begin.

It's a proper boxed RPG experience. The additional cards and updated rulebook give you useful physical tools rather than simply putting a book inside a bigger package.

And, yes:

Tiny mice. Enormous bravery.

We're very susceptible to that combination around here.
