An apocalypse broke out about a year ago. Man turned into zombie. Everything was in ruins and stopped working. Zombies were dangerous, but so were the survivors. Some of them turned into cannibals or killed other survivors for their loot. So Eren made it a point to stay clear of those survivors. He was walking with his back pack and gun down an abandoned road, searching for a place to stay for the night. As he was walking he heard something in the forest, aiming his gun by reflex.
