Fallout: The Enclave of the United States of America & Artificial Intelligence Machines Project

This high-tech expansion introduces the Enclave, a faction that claims to be the legal continuation of the United States and seeks to restore the nation after the nuclear war. It adds Enclave citizens, advanced technology, artificial intelligence machines, and cyberpunk elements to the post-nuclear setting. The material is intended for experienced characters from the Wastes, typically level 12 and above, or for campaigns that begin with level 1 Enclave characters. Its technology and themes can be incorporated selectively into an existing campaign.
