Major League Gaming

Major League Gaming, commonly referred to by their acronym MLG, is the largest organized league for international completive gaming for a number of console video games. Every year MLG holds a tournament called the "MLG Pro Circuit". Founded in New York City in 2002, MLG focuses on creating rosters, holding tournaments and defining professional competitive gaming for over 28 countries worldwide. MLG operates on a series of media outlets such as television, and more importantly the internet. Gamers can visit MLG, and access any number of content from past tournaments, to tips and tricks and more. Currently MLG caters to Gears of War, Rainbow Six: Vegas, Shadowrun, Halo 2, and Halo 3.

At MLG tournaments, players do not need to bring any equipment in the form of televisions, game systems except their controller. Although, some players bring their systems to practice the game prior to the tournament. MLG is fully sponsored, and thus provides all players with 20" flat screen televisions, necessary networking equipment and cables, and video game equipment. Typically, each MLG event is held over the course of a weekend (Friday through Sunday) in a major city throughout the United States. The only exception is the Playoffs/Championship, which occurs over a period of four days.

Halo 3
MLG posts videos of their matches on Bungie's Community Videos and are usually featured on Bungie Favorites. Also, there are the official gametypes (like MLG Slayer, MLG Capture the Flag, etc.) and maps (where item/weapon placement and duration are tweaked to make the game more competitive.

Pro Circuit
The Halo 2 Pro Circuit, features a 4v4 bracket, where two teams of four players pit themselves against each other in Team Slayer, Team Ball, CTF, and Assault, or a Free For All (FFA) bracket where players take to the game solo. The tournament is split up into six major events; five regular season events and playoffs/national championship.

The open 4v4 tournament consists of a 192-team double elimination bracket. Teams that lose once move to the Loser's bracket and still have a chance to finish first by playing the winners of the Winner's bracket. If a team loses twice, then they are eliminated. The championship 4v4 event is similar to the open 4v4, except it consists of on 32 teams. Each match in the bracket is a best-of-5 games match, where the first team to win three games will win the match. The top eight teams by final placement in the championship 4v4 will win prize money, but the 32 teams in the championship event will also earn rank points for that season.

Comparable in nature to the 4v4 tournament, the FFA is individual based where no more than 1024 players can join. This is a single elimination tournament consisting of 8 players per game. Advancement from the open FFA to the championship FFA, is granted to sixteen players regardless of status or seed. The championship FFA consists of a 32-player Round Robin tournament and a final championship game, in which each competitor will play against all other competitors at least once, regardless of winning or losing a game. The final championship game will be a standard FFA game, where all eight players will earn prize money determined by where they place in the game.
