s.

Unisystem was developed by C.J. Carella for the first editions of his WitchCraft and Armageddon role-playing games,
published from Myrmidion Press. Eden Studios uses Unisystem under an exclusive license, but has offered other game companies to license the system from them. Eden Studios published WitchCraft 2nd Edition and their original All Flesh Must Be Eaten games as Unisystem games. Armageddon 2nd Edition and a new 2nd Edition of Eden's own Conspiracy X were later published, also using this gaming system.

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 (be it a Gifted human, a Vampyre, a Spirit, and so on) or detail what sort of magic they can do.

Actions are resolved by adding together the character's relevant Attribute, the applicable Skill, and a ten-sided die roll, plus any modifiers for difficulty; if the total is nine or greater, the action succeeds. Gamemaster

s (called 'Chroniclers' in Classic, and 'Directors' in Cinematic Unisystem) are also given tables of successes: characters that get a higher roll than the required nine have bonuses on their final outcome; this table describes how successful they turn out to be, and gives guidelines to figure out the resulting bonuses.

Classic versus Cinematic

Unisystem can be divided into two sub-systems; Classic and Cinematic.

Classic Unisystem was developed first and is featured in All Flesh Must Be Eaten, Armageddon, Conspiracy X 2.0, Terra Primate

and WitchCraft. It is typified by grittier, more realistic play, greater attention to detail in skills and combat, and the use of Secondary Attributes that are typically derived from the Primary Attributes. Essence, or the measure of life-force and magic, is also central to Classic Unisystem play.

Cinematic Unisystem was designed to mimic the “cinematic” exploits of characters. First developed for the Buffy the Vampire Slayer Roleplaying Game, it was later adopted for use in Angel,

. Cinematic features a limited set of skills that cover most situations, no Secondary Attributes or Essence, simplified combat and flat damage resolution. Cinematic games also feature the use of Drama Points which allow the character to do things above and beyond what they could do under the system alone.

The chief difference between the systems are the use (or lack of) Drama Points, and differences in magic sub-systems; essence-based vs. Sorcery/Magic.

Despite the differences the two are still largely compatible, though every Cinematic Unisystem game offers an appendix for a more complete conversion and the Buffy RPG’s Magic Box supplement offers an appendix on converting between Buffy’s Sorcery magic system and Classic Unisystem’s WitchCraft RPG based essence.
