Matthew ‘Zyos’ Leto maintained his champion status in Halo in WCG 2004 Grand Finals following his victory in WCG 2003. A college student majoring in Information Systems at the time, he would become the most prolific gamer in the world when playing Halo.

Matthew Leto participated in the WCG for the US team and showed his excellent skills and strategies to the world. He accumulated nothing but victories and earned his first title in WCG 2003 Grand Final (the first event which had console game events). He then defended his championship after earning victories in all matches but one in WCG 2004. This earned him the right to become the first console player to be inducted into the Hall of Fame.
