Unisystem

From Wikipedia, the free encyclopedia

Unisystem is a generic role-playing game system produced by Eden Studios, Inc. It is used in All Flesh Must Be Eaten, the Buffyverse role-playing games, CJ Carella's WitchCraft, Conspiracy X (2nd Ed.), and several other games.

Unisystem was developed by C.J. Carella for the first editions of his WitchCraft and Armageddon games. Eden Studios uses Unisystem under an exclusive license, but has offered other game companies to license the system from them.

[edit] Gameplay

Unisystem games use a point-buy system to generate characters. Points are then spent on Attributes, Skills, Qualities and Metaphysics. Drawbacks can then be used to gain extra points.

Attributes represent the character's main six abilities, which in this case are three physical attributes: Strength, Dexterity, Constitution; and three mental attributes: Intelligence, Perception, Willpower. Characters also have a variety of skills, and Qualities and Drawbacks to give the character added perks or faults (respectively). Other Qualities and Drawbacks are of a Supernatural sort and are used to designate a character as a particular type of character (Gifted, Bast, Spirt, and so on) or detail what sort of magic they can do.

Actions are resolved by adding together a player's relevant attribute and skill to a ten-sided die roll and any modifiers for difficulty; if the total is nine or greater, the action succeeds. Gamemasters (also called Directors in Cinematic Unisystem) are also given tables of successes, and, if you get a higher roll than nine, you get added bonuses to your success based on a table.
