Never in a million years did anyone ever think that the world would actually become an apocalypses. And yet, it did. People did what they could do to survive. Whether it was from the invaders, other people, or themselves. Some people went solo, others formed groups, other joined the rebellion...which was a death wish. People who went to the rebellion typically died. People who stayed in groups lived longer, but had a higher chance of starving because they had to share their food and water. People who went solo either died first, or lived the longest. It just depended on what lengths you were willing to go to.
