Building Better Worlds
A complete campaign supplement for the official ALIEN roleplaying game, focused on exploration and colonization at the edges of human space. It expands character creation with new archetypes, adds equipment, weapons, spacecraft, 36 worlds, colonies, and new Xenomorph species. The book provides a sandbox campaign set in the Far Spinward Colonies, including seven missions that can be played in any order. Tools for creating worlds, establishing settlements, and running open-world expeditions support campaigns as explorers or colonists.
