Fuzion is noted for its anime-genre support, customizable rules flexibility, and being one of the first generic game systems to be released for free over the internet.

A modified OGL set of rules based on Fuzion is published by Gold Rush Games as the Action!

CPs are used to buy levels in Primary Stats which are the basic attribute abilities of the character.

The actual type of currency is dependent upon the genre being played, (for instance a fantasy medieval-era game may use gold pieces, a modern action game set in the United States would use dollars, a sci-fi future setting may use galactic credits).

Certain campaigns using the Fuzion system can have Power Points (PPs), which are assigned to the players by the Referee just like CPs and OPs.

Fuzion is a flexible and easily modifiable system, so more Stats can be added to any category by the Referee as they see fit.

If the Referee feels there is no real difference between Dexterity and Reflexes, they could remove one or the other, and use a single Stat for both.

In a way, they are similar to Advantages in GURPS, or Feats in a d20 System game, and offer benefits to the character.

Some Talents include: Combat Sense, Lightning Calculator, Photographic Memory, Light Sleeper, Speed Reading, and Ambidexterity.

Each Complication returns a number of points based on the hindrance they give the character, and how often they crop up in the game.

They usually include Special Equipment, Security Clearances, Licenses, Permits, and Contacts (who a character can use to gain information or call in favors from).

Lifepaths are an optional way to randomly generate character backgrounds and personalities through a series of tables.

Some Lifepath choices could give a character a special Talent, Complication, or Perk for free.

Templates are featured in certain Fuzion campaigns, which can be chosen by players to help design a well rounded character suited for a specific career, (such as police officer, soldier, doctor, etc.).

Templates explain things about the character's job, and give a listing of particular Skills, Talents, Complications, Perks and starting equipment.

In Fuzion, whenever a character performs some kind of critical action that needs to be resolved, they make a die roll to see if they succeed or fail at the task.

When resolving a contest between characters, the DV of the check is the result of the opposing force's roll or, to save time, the Referee could add a set number, "+X", to an NPC's abilities (typically +10 when using 3d6 or +5 using 1d10).

This the opposite of Fuzion's parent, the HERO System (which is similar to the GURPS mechanic), where the roll must be equal to, or less than the target number to succeed.

If a character's Stat + Skill already meets or exceeds the DV, it is usually considered an automatic success without making a die roll.

A Critical Failure may represent something more disastrous happening to the character as the Referee sees fit.

A Critical Failure on a Lockpicking task, for example, could trigger a silent alarm the character wasn't aware of.

During a Phase, a character can perform one of several Basic Actions, such as Attack, Block (Parry), or Move.

The character in a party with the highest Reflexes stat acts first, or they can hold the action and wait to see what someone else is doing.

When making an opposed roll against another character, (or NPC), the resolution is handled differently and attempt to counteract what the opposition does.

When an object loses all its SDPs, it is rendered useless; (a vehicle shuts down and grinds to a halt, a weapon will no longer fire, etc.).

Each point of DC represents a six-sided die that is rolled to see how much damage the weapon can cause.

For instance, a lightweight handgun typically has a DC of 3; meaning 3d6 is rolled to determine the damage it causes when it hits something.

A character must possess the listed minimum level of STR to fully inflict the weapon's damage.

Using Hit Locations allows Called Shots with a -4 penalty to an attack roll to strike a specific area.

Enough OPs that are saved up can later allow a player to raise a Stat or two, and maybe buy a Talent or Perk, however the price for future ability upgrades becomes costly and keeps characters from becoming too powerful, too quickly.
