7th Extinction Core Rule Book
Set in 2399, the game presents a bleak science-fiction future a century after the Caentari Alliance’s invasion of Earth. Humans and aliens now coexist, while the survivors face the self-aware planetary defence system AEGIS, monsters emerging through tears in space and time, and violent storms that disrupt technology. The core rule book provides the setting and rules for creating and playing characters in this post-invasion world.
