From the back of the book:
"OUTLAW is the Western sourcebook for the Rolemaster and Space Master systems, providing enough information to run Western adventures in either the historical or fictional Wild West. From lassoing a wild stallion to sliding a low-down cowpoke down the bar and through the window, it's all here. Use Outlaw as a supplement for your existing Rolemaster or Space Master game, or start your own Western campaign.
Outlaw includes:
Guidelines and optional rules for Western-style maneuvers and combat.
A Western sourcebook containing a timeline, general information, and descriptions for Western equipment and weapons.
A complete campaign setting based on the Western town of Deadwood, Dakota Territory.
Two complete scenarios, numerous adventure ideas, and advice for running your own Western campaigns.
Dozens of Western NPCs, including famous historical figures like Wild Bill Hickock, Calamity Jane, Butch Cassidy, and Billy the Kid.
Layouts and descriptions for Western towns, the OK Corral, an 1800s train, a bar, and other Western locations.
Note: Outlaw is not a complete role playing game. Ownership of Rolemaster or Space Master is required.
Warning: Outlaw contains much of the same information found in Western Hero. If you have Western Hero, we suggest that you do not purchase Outlaw."
