Now open for registration at the offical Guitar Hero website, fans will compete to get the highest score possible playing Monster’s “Matchbook Romance” during the Guitar Hero III: Legends of Rock challenge. Activision will donate up to $55,000 to the Starlight Starbright Children’s Foundation by donating up to $1 for each participant who registers to play in the event, and $100 for every 1,000 points scored by the challenge’s highest individual score. The funds will go directly to Starlight’s programs, helping seriously ill children and their families cope with their pain, fear and isolation through entertainment, education and family activities.

During the same time period, Activision is also sponsoring a second, private Guitar Hero III: Legends of Rock challenge, specifically for the seriously ill teenagers and their siblings that are a part of Starlight’s Starbright World online community. The highest-scoring rocker from the Guitar Hero community and the highest-scoring rocker from the Starbright World community, at the close of the competition will receive an all-expense paid trip for two to Southern California and a tour of Neversoft Entertainment – the developers of Guitar Hero III: Legends of Rock.

All Guitar Hero fans interested in participating should visit www.guitarhero.com before 7:59 PM (EDT) on May 2nd, 2008 to sign-up. Both competitions kick-off at 8:00 PM (EDT) on May 2nd, 2008 and will conclude at 7:59 PM (EDT) on May 5th, 2008.
