Publisher of tabletop roleplaying games, wargames and board games, Modiphius Entertainment has shared that the previously announced campaign book for the popular tabletop roleplaying game for Bethesda’s Fallout, Royal Flush will now be released in Q4 2025.

Royal Flush takes players back to New Vegas and the Mojave Wasteland, where they will discover and attempt to dismantle a plot to bring war back to the West. Starting in New Reno—as all good stories do—by finding a body in a ditch, the players will deal with the criminal underbelly of the city, hired to find out what happened, and investigating the sudden boom in military grade firearms suddenly in the hands of the least likely, and most bloodthirsty, groups in the area. With so many bullets available, old tensions begin to rise, and it is only a matter of time before that much firepower causes the entire Mojave to explode, unless someone does something about it. The campaign book will give players the opportunity to visit New Vegas and explore a new region of the Mojave.

The publisher has also announced that a solo roleplaying title is in development under the name Lone Wanderer. Based on Bethesda’s hugely successful Fallout series, it will use a similar format to the popular Modiphius game, Star Trek Adventures’ Captain’s Log, allowing players to record their adventures and play an RPG in the wasteland without the need for a gamemaster.

Lone Wanderer will be based on the 2d20 System, and will procedurally generate a story for players that allows them to explore the wasteland as their character emerges from a Vault-Tec vault, immersing them in the post-atomic United States without a group or GM. Players will also be able to play as a number of other Fallout characters, like survivors, ghouls, super mutants, and robots.  The solo edition is due to be released in 2026.

Modiphius also has plans to develop and publish sourcebooks for the tabletop RPG that delve further into the history and geography of the different discrete areas of the wasteland, from New California and the Mojave, to the Capital Wasteland, the Commonwealth, and the Appalachian Wasteland.
