"The game's story is set in a post-apocalyptic Australia, where mutant animals form the predominant societies. Tasmania is the bastion of technologically advanced civilization, while the mainland is largely under the sway of the aboriginal Dreamtime philosophy. Invading forces from Jakarta, comprised primarily of human and mutant Water Buffalo forces, threaten both ways of life. It includes rules for many species of native Australian and southeast Asian animals, as well as riding insects, and various airships.
This thrilling sourcebook takes you to the fabulous outback of Australia. It is a very different world than the savage Americas. Man and animal live in peace, but a new threat from the north threatens that peace.
