The world was once filled with humans living their everyday life until a virus broke out that cause the recipient to lose control of their body, cough up black ooze and their eyes suddenly start seeping out a black gaseous liquid. At first, they thought it to be a simple alien bacteria that travelled on one of the many space shuffles, but as they examined it they found that it was actually a much older disease and that it somehow had a mind of its own... it spread through the entire world, not as quickly as assumed a theoretical zombie apocalypse giving the Human Race enough time to secure one island country for the people to live without fear of infection, Australia.
Now the threat is no longer what is outside of the walls of Australia, but the real threat is inside with a tyrannical government ordering the civilians to bend to their every will. Not everyone is willing to bend especially a ground going by the name The Anti, they track down a small team who have been to the infected mainland to acquire their help and expertise and together they want to stop the infection and the leader of New Australia.
