Mercenaries, Spies and Private Eyes (MSPE) is a tabletop role-playing game designed and written by Michael A. Stackpole and first published in April 1983 by Blade, a division of Flying Buffalo, Inc. A second edition was later published by Sleuth Publications in 1986, but Flying Buffalo continues to distribute the game. In 2019 a new revised Combined Edition of MSPE was published by Flying Buffalo which brought the different material from the previous editions and included additional new rules and expansions to the original rpg. MSPE'''s mechanics are based on those of Tunnels and Trolls, with the addition of a skill system for characters. A few adventure modules were also released for MSPE. System CharactersMSPE determines character attributes by random roll. Skills are purchased for the character by the player using Skill Points. Skills are available in multiple levels, but skill cost goes up exponentially as the level of the skill increases. Game mechanics The core game mechanic of MSPE is the saving throw. Unlike Dungeons & Dragons' saving throws, those in MSPE are not used solely to escape danger. Instead, the MSPE saving throw is an attribute roll. The Gamemaster determines the difficulty of the saving throw, and the player then rolls two six-sided dice and adds the value of the relevant attribute of his/her character. MSPE saving throws can also be modified by skills, in which case the level of the skill being used is also added.MSPE uses a "loose" skill coupling, where any skill can potentially be used in combination with any attribute. In contrast, many other role-playing games use a "tight" coupling, where each skill has an associated attribute and is used only with that attribute. For combat, MSPE uses the same system as Tunnels and Trolls, with expanded rules for missile weapons (due to the importance of guns in the modern era) and additional rules for martial arts. Character advancement Characters in MSPE earn Adventure Points (APs) on the basis of the "risk and daring" taken (decided by the gamemaster), success in combat, how well the characters handled their mission, and saving throws made. Gamemasters also have discretion to give out bonus APs. Earning enough APs causes the character to increase in level, and each level gives the character points to add to attributes (which can indirectly give more skill points). In addition to overall APs, MSPE characters also earn Skill APs by using their
