Aces & Eights is set in an alternate history time line in which the American Civil War happened ten years earlier and the United Kingdom and France assisted the Confederate States of America (CSA). The Civil War lasted for ten years and both sides ground to a halt as resources and manpower started to run low for all concerned. The Republic of Texas never had a chance to join the Union and was neutral. With the Union tied up in a war of attrition with the CSA, the "Indian Territory", modern-day Oklahoma, was able to form their own government and withdrew from the Union. Mexico still owns much of the modern day western USA but does not have the manpower or money to govern it properly.
Kenzer & Company first published a set of basic combat rules called Aces & Eights: Showdown in June 2005. Showdown covers just the basic character creation and combat rules of the game along with a few sample scenarios and a map of the fictional towns of Lazarus and Black Horse. Aces&Eights: Shattered Frontier was released in June 2007. It includes all of the rules from Showdown in the basic combat chapter but includes a more detailed character creation and "Advanced Scrapes" chapter along with the expanded Setting and additional rules.
