The awards are based on individual categories. The categories range from "Best Sniper" to "Best Trash Talker". Team 3D's dominance is shown by a top 3 award in nearly every category.

"Welcome to the First Annual MLG Pro's Choice Awards! Throughout the 2005 Halo 2 season, we've seen a lot of hard fought battles over huge cash prizes and the right to be known as the best players in the world. While our upcoming National Championships will decide which teams and players were the most successful this year, we thought it would be interesting to find out who the best individual players are in a variety of categories that can't be determined by team records or tournament finishes. To find this out, we turned to the people who would know best: the pros themselves."
