That's one question the game need to answer in season 2. I mean for such a huge apocalypse, assuming worldwide, i wonder why nobody in the game question that. How could the government let it become that big and nobody, even the media, noticed ? During the first season, the group have been staying for three months with a military woman and an airforce guy but they didn't bother asking them about cause of the apocalypse. And where was the military? i thought it was strange that seeking the government's help wasn't the first thought they had.
