Interlock System

The Interlock System is R. Talsorian Games' proprietary roleplaying game system, originally created for its Mekton and Cyberpunk series games. The system uses ten-sided dice, nine attributes, and is skill-based, rather than class-based. Character creation also uses a unique Lifepath system for semi-randomly generating a character's background. The core mechanic of the Interlock system is rolling a d10 and adding the relevant stat and skill bonus, both rated on a scale from 0-10. The final result is compared to a target number set by the game master based on the difficulty of the task at hand, usually ranging from 12-20. Meeting or exceeding this difficulty means the action is a success. There is also the potential for critical success and critical failure depending on the d10 roll. Characters in the Interlock system are the sum of their attributes and skills. Attributes have a minimum value of 2 and go up to 10, and skills start at 0 but can also raise to 10, representing the maximum possible skill level. There are no character classes in Interlock, with players defined by the skills they specialize in, though some games include "profession packages" of suggested skills for particular jobs in the world. Interlock also includes a character background generation system called Lifepaths. Through a unique combination of random rolls, you can produce a unique character with an eclectic blend of life experiences. These create narrative hooks for the character, like personal connections, style, family, life events, and employment history. The Interlock System is probably best known for its use in the Cyberpunk RPG series, including Cyberpunk 2013, Cyberpunk 2020, and Cyberpunk RED.
