May 20 The new's is saying a "epidemic disease" has been found. Until further notice, we stay inside our homes. May 22 School's cancelled. That's all that matters. I think I might like this "epidemic disease" May 25 They are setting up Quarantine Zones all over the country. I heard my parents talking about them. We might pack up our stuff and go. May 28 We just arrived to our Quarantine Zone. The trip was.. Disturbing. Some sort of gang we're looting houses. June 3 Rumors say the disease has infected the country already. Is it really true? June 16 Government broke down. Havoc lurks the streets. Scientist say the disease might evolve into the air we breathe in. June 24 We are now wearing gas masks. Some people didn't get any because of supply shortage. They are terribly sick. Spewing their lunch, rashes on their skin, it's disgusting. July 3 The latest vaccination shots have failed. This increased the population of infected people. July 6 People are arguing. The people who run the Quarantine Zone have disappeared. They say they couldn't handle the pressure and left us to die. July 17 A battle broke out. This Quarantine Zone is destroyed. My parents died in the battle. I'm left alone. August 3 I was looking through my stuff when I found this journal. A lot has happened. The disease destroyed the world. There are hardly any survivors. A group naming themselves Smugglers is one of those solo groups. Survival of the fittest. I found an abandoned Quarantine Zone. I live there now. By myself. And no one else
It's good, and I love that zombie-esq feel, but you need much more detail. This could be a sort of prelude to a story, giving you a basis for the world.
Bandits. Probably Smugglers. Their footsteps thumping the ground gave out their location. I've already been through situations like these. I quickly scurried along the Quarantine walls getting to one of the defense towers. Only about four of had came through. I climbed back down and hid right behind a shattered barricade and listened carefully. I could hear their foots steps trailing off as I let out a breath. I stood up looking around. My break ended after something grabbed me from behind,"Got you now, Rat!" I struggled get out of his grip. With all might strength, I stomped on his foot, causing him to loosen his grip while crying out in agony. I punched his stomach, knocking the breath out of him. I pushed him onto the floor, slid my fingers under his mask and pulled it off. His eyes widened in horror, knowing his fate. I got off him and looked down at him. "Who's the rat now?" I felt a sharp pain at the back of my head and my vision was poor. I was on my hands and knees and turned my head back. He had a pump shotgun. Immediately, he pulled the trigger. I barely rolled out if the way and got up to try to steal his weapon. I muscled the shotgun off him, hitting him with the butt if the gun. I could see his blood splatter inside his mask. I aimed through the sight and squeezed the trigger. You could imagine what happened next. I heard footsteps as I quickly dove behind a dumpster. "Oh crap! W-what happened?!" "We gotta get out of here man, I don't want to end up like them.." His friend said. I heard their footsteps trail off in the distance. Another fight won.
Is this a series of journal entries or a narrative? It helps to be consistent, even if the descriptions are a little bit undeveloped.
