Publisher description: "Mercenaries, Dogs of War, a role-playing or miniatures game of late 20th century mercenaries. Rules include complete weapons lists, character generation, scenarios, maps, floor plans, which are excellent with or without a GM." This version of the core rules includes two rulebooks plus a number of stapled-in inserts consisting of maps, charts, and tables. The primary rulebook has a cover printed on green stock. The second rulebook, with a cover made of white stock, is marked inside as "Volume Two" and "Book Two." Comments in the rulebooks indicate that the second rulebook was created to add revised and updated rules that arose from further playtesting.
