Howling Wilderness is a sourcebook of the United States of America for use with Twilight: 2000... It describes the events in America during the years leading up to the war. It describes the preparations for nuclear attack taken by the government, and why many of those preparations failed. It describes the attack upon the United States in November of 1997, and the aftermath of that attack. In addition, it carries the Twilight: 2000 future history through May of 2001, and summarizes conditions in the U.S. as of that date. It will also deal with the shift in weather patterns in late 2000/early 2001, and the effects this will have.
