Urban Rivals is a massively multi-player online virtual trading card game.

The game features over 2,000 characters with varying rarities and abilities to discover, collect and level up by fighting live against players from all over the world.

Each character has specific Power and Damage values, and belongs to a clan.

[1] 4 new characters are added every two weeks, and included in the 'New Blood' pack in the shop, which contains the 35 most recent additions to the game.

In addition, each player starts the battle with 12 Pillz, with 1 free Pillz given at the start of each round, and 12 Life, except in ELO Fighting Championship, where each player begins with 14 Life.

If there is a tie for Attack value, the card with the lower star count wins.

The battle ends after 4 rounds, with the winner being the player with the greater number of Life Points remaining.

The battle also ends once either player loses all of their Life Points, called a KO.

A player's level is based on their cumulative number of Battle Points (BP).

Top 150 players will split the tourney jackpot, also based on their final rankings.

[5] There is also a more strategy-based weekly ELO Fighting Championship (previously known simply as ELO), with stricter deck-building rules, such as the star count limit of 25 (as in T1) and the fact that certain cards cannot be used, based on weekly player vote and staff regulation.

In EFC, there are six zones based on players' points accumulation, namely "Dark Corners", "ChocoMuscle Ring", "Danger Zone", "EFC Tower", "Polit Arena", and "Z Palace".

[6] On December 8, 2008, the game added a new Event creation feature, allowing players Level 40 and up to create their own customized tournaments.

Rules can be set with a high degree of flexibility, in terms of scoring, matchmaking and more.

An annual competition at Urban Rivals is held every year to crown the "Most Beautiful and Talented Woman of Clint City".

The rules are very simple: All female characters released in the year are eligible for the contest.

After overwhelmingly negative responses from the players over the cancellation, the UR staff brought back Miss Clint City in 2010.

Clans of Urban Rivals refer to the groups fighting for supremacy in Clint City.

Each character also has Power and Damage stats varying between the characters, accompanied by various abilities to complement their respective clan's bonus, in addition to name banner colors that determine their rarity (Common, Uncommon, or Rare).

On some occasions, the staff announce which characters will be retired from the shop up to a few weeks in advance via the homepage news.

As the tag implies, these cards feature Christmas-themed artwork, and often have different stats and abilities to better distinguish them from their original versions.

Introduced in November 2010, they are special cards that can only be obtained through the completion of a series of clan-specific missions or from Arcade Mode, and can neither be traded nor sold.

Formerly included in the entire character roster were Rebirth cards (tagged Rb).

Introduced in January 2015, they were old characters that were re-released in the form of cards with new artwork, although their stats and abilities remained unchanged from their original versions.
