Delve into the Universe of The Expanse Novels by James S.A. Corey.
Create your own characters and live your own stories with The Expanse Roleplaying Game. From the streets of Earth and the valleys of Mars to the stations of the Belt and the systems beyond the Ring, the universe is yours to explore.

The Transport Union Era is Perfect for Roleplaying
This updated core rulebook is set between the events of Book 6 (Babylon’s Ashes) and Book 7 (Persepolis Rising). This is a fantastic time to set an RPG campaign because there’s untold history and a lot of unexplored territory. The thirty years between novels gives Player Characters room to shine and write their own chapters in the history of The Expanse.

100% Compatible with all previously released material for The Expanse RPG
The Transport Union Edition expands the background and rules but the core game of the original 2019 edition remains the same. Previous supplements like Ships of the Expanse, Beyond the Ring, and the Sol System remain great and useful resources. The Expanse RPG virtual tabletop is also being enhanced as part of the Transport Union Edition with full compendium support coming to Roll20, along  with official support coming to Foundry, allowing you to play the game online with your friends wherever they are.

Three New Supplements to Choose From
Daemon’s Gambit is a new adventure series set in the Transport Union Era. Free Navy Conflict presents this apocalyptic era for play and includes an adventure series. Crew Companion is the first player-focused book for The Expanse RPG, and it includes loads of new options for your PCs.

Dice and Minis and More—Oh My!
We are going all out with this campaign. You can expect new dice sets and, for the first time, official Expanse miniatures for characters and spaceships. Plus, some fun surprises!
