ALIEN RPG: Building Better Worlds gives players all the tools they need to run open-world campaigns. The book includes the history of colonization, expanded character creation rules for frontier life, and a chapter filled with new gear and spaceships. It also features an Extrasolar Species Catalog that has new Xenomorphs to encounter on distant homebrew planets. There are also six expeditions to play through contained in this book.

Free League Publishing also recently announced Tales From the Lone-Lands, the second expansion for The One Ring 2E RPG (see “'The One Ring 2E'").
