The Gazetteer is a sourcebook for global hot spots in the strife-torn world of Merc: 2000. From the coup in Tongfa to the border dispute between the Russian Republic and Japan; from the Second Nigerian Civil War to the Basque Insurgency in Spain; from the frigid steppes of central Asia to the steaming jungles of South America; from the battlefields of West Africa to the crime-torn streets of America; the Gazetteer covers then all. Every aspect of warfare in the year 2000 and beyond is presented, ranging from brushfire wars in remote parts of the globe, to terrorist activities in our own backyard.

Every major world trouble-spot in the year 2000 is covered with maps, a background summary of the conflict, military organizations of the participants and suggestions for conduct of adventure scenarios as part of the conflict.

Although it is intended for use with Merc: 2000, most of the information presented inn the Gazetteer can also be used with Twilight: 2000.
