AuZtralia: TaZmania is a dual-map expansion for AuZtralia designed specifically for 1-2 players, or (if playing with the Revenge of the Old Ones expansion) three players. One side has a fixed map that is surveyed for resources and Old Ones, while the other side is randomized through a set of 66 terrain tiles.

Humanity came to build a new world after a long war against the Old Ones. They failed. The old terrors were waiting for them and pushed them back to the coast. Now their only hope lies in a nearby small island, TaZmania. Will this be the promised land?
