Alternative Vector: Mr. Madison's War
An alternate-history roleplaying campaign set during the War of 1812, in a timeline where the United States suffers a decisive defeat at New Orleans. British forces reoccupy former colonies, several states return to English rule, the slave trade expands, and a new Native homeland emerges. Players create characters and take part in this altered American history using the Cepheus Engine and OSR-style rules. The campaign includes historical background, streamlined character generation, expanded equipment, terrain movement modifiers, wilderness events, and options for customizing a character’s cultural background.
