Infection Z 2: The Apocalypse

It's been 4 months since Nathan and Tyler lost their home, their parents, and almost their lives. Not only did Infection Z had spread throughout the country, it spread throughout the entire world. They now find themselves in Chicago, Illinois, where the horde has also ravage the city. When they were faced with certain death, a group called the Phoenixes saved them.

Can Tyler and Nathan survive with this new group, or will they end up with their faces down in the middle of the street, or will they end up as just another couple undead corpses to feast on the rest of the living?
