Gangbusters (role-playing Game) - System

System

Character generation in Gangbusters follows a pattern common in role-playing games of the early 1980s—a player randomly generates his character's abilities (such as Muscle and Luck) using dice, then chooses a career (character class) for the character. Careers for player characters are limited to Criminal, FBI Agent, Newspaper Reporter, Police Officer, Private Investigator, and Prohibition Agent. Each career includes a unique set of advantages and disadvantages to differentiate it from the others. Characters are further customized by adding non-career skills, such as Auto Theft or Photography.

Characters are improved by earning experience points. Experience points are awarded (by the gamemaster, called the Judge in Gangbusters) based on a character's success in his career. For example, criminals earn experience points based on how profitable their crimes are, while police officers earn experience points for capturing criminals. Earning experience points increases a character's level (which is an indicator of social status in the game setting), and allows the character's player to improve the character's abilities and purchase new skills.

Gangbusters uses a percentile-based mechanic for most task resolutions. The basic chances of a character succeeding at an action are equal to the character's score in a relevant ability or skill, subject to modifiers assigned by the Judge. The player of that character then rolls percentile dice to determine if the character succeeded. The results of actions (such as the damage caused by weapons or the amount of money produced by a criminal enterprise) may be determined by further dice rolls. All dice rolls in the game use ten-sided dice.
