The Black Death has reached Europe and it’s up to you to save your people. In Rattus: Big Box players are work to keep their populations alive while settling the various regions of Europe. Players take turns choosing a class and placing pieces on an area of the board. At the end of your turn you move the plague marker to a neighboring area. As the plague moves around it affects rats and player pieces.

Rattus: Big Box includes not only several previous released expansions and promos, but also previous unpublished materials, modules, and bonus cards. More specifically, this renewed edition of the Rattus line contains all materials of the base game and the Pied Piper, Africanus, and Academicus expansions. Additional new content is included, and players can add the new "Guilds & Inns" and "Bonus" modules to create even more variety and challenge. This edition also contains popular bonus cards like The Judge, The Jester, and Boccaccio, as well as all 27 level upgrade tiles.
