Urban Rivals is a shockwave based massively multiplayer collectible trading card game available at http://www.urban-rivals.com/. The basic premise of the game is simple. You are a gang leader in the city of Clint, a fictional locale where gang warfare rules, and where combatants from all over the world come to show their stuff. The gangs that inhabit Clint range from the mundane to the bizarre, stretching from preps, jocks, nerds, and thugs on one side to ninjas, robots, zombies, and aliens on the other and everything in between. It is up to you to gather up gang members from all the gangs in the city to become the number one city boss. That's about it. It's corny and cheesey and kind of cartoony and that is great because it meshes perfectly with Urbal Rivals's corny cheesey kind of 80's Saturday morning cartoony feel. After all, you can't really see a space cowboy fight against a zombie pirate without a taking it with a smirk and grain of salt.
There is only one type of card in Urban Rivals, and that's the Character card. Character cards have 4 important traits to take note of: Power, Damage, Character Ability, and Clan Ability. Power reflects how likely a character is going to win in combat, Damage is how much damage will be done to an opposing player if that character wins in combat, Character abilities are static abilities that aid you simply by having that character in play, and Clan abilities are static abilities that aid you if you have at least one other member of that characters Clan or Gang in play at the same time.

To play a game, you simply build a deck with a minimum of 8 characters that conforms to the rules of one of the four Urban Rivals formats. When a game starts 4 of your characters are randomly selected and automatically played to the field. You and your opponent then take turns choosing characters to send into combat. Players get to see each other's character choices when they are made, so choosing second has a bit of an advantage but the first picker alternates each round. Characters can only fight once per battle, so be sure not to send your major fighters to bat right at the start or you will be weak late game.

When you send a character into combat you may use “Pillz” to augment its stats. Spending pillz on power multiplies that character's power value by the amount of pillz you spent plus 1. Therefore if a character has a power of five, spending 1 pill makes it ten, 2 makes it fifteen and so on. You can also spend 3 pillz once per character to increase that character's damage by 2. Your chance of winning any particular character battle is your character's final power compared to the total power of both combatants. So let's say your character has a power of 7 and your opponent's character has a power of 9. Your chance of winning the battle is 7 out of 16 and your opponent's is 9 out of 16. However, if your character enters battle with a power total more than twice the opposing character's, he automatically wins the fight. When a character wins a battle it takes a chunk out of the opponent's life points equal to the character's damage rating. You start each game with 12 pillz and 12 life. First player to reduce their opponent to 0 life, or the player with the most life at the end of 4 battles wins. Simple enough right?
