Last Three Hours: Fortress of Rage

Damon Burke's fiancée and a local thug got him to trust them, then killed him and ate him after the apocalypse began. He woke again three hours before it started, with the Emotion System, which ran on points, and with the whole of the first time still in his head. He took out every online loan he could get, sold off his property, and put all of it into supplies. He settled with the fiancée and killed the thug. After that he took over his apartment building, and from there the compound, the surrounding district and eventually the city, working out as he went where the apocalypse had come from.
