Guitar Hero World Tour

FOR IMMEDIATE RELEASE

SANTA MONICA, CA – August 8, 2008 – After performing in countless sold-out arenas and amphitheatres throughout the world, rock’s defining frontman Ozzy Osbourne – who has sold over 100 million records worldwide in his four decade career – will be playing to a new audience this fall as he makes his videogame debut in Activision Publishing, Inc.’s (Nasdaq: ATVI) Guitar Hero® World Tour.

Budding rockstars around the world will have the opportunity to live out their ultimate fantasy on the virtual OZZFest stage, playing as Ozzy, or alongside him, as he wails to iconic rock track “Crazy Train” and “Mr. Crowley,” both from his quintuple platinum debut solo album Blizzard of Ozz. OZZFest, now it its 13th year, has also been created digitally as an in-game venue exclusively for Guitar Hero World Tour to host the heavy metal rock legend.

Joining Ozzy in Guitar Hero World Tour as a playable character is his lead axe-shredder and founder of Black Label Society, Zakk Wylde, performing their hit track “Stillborn.”

In addition to Metallica releasing their highly anticipated Death Magnetic album in its entirety as downloadable content in both Guitar Hero® III: Legends of Rock and Guitar Hero World Tour, the 2008 OZZFest performers and GRAMMY® winning recording artists will be appearing for their on-disc encore with “Trapped Under Ice.” Finally, taking the Guitar Hero® stage for the first time is fellow OZZFest artist, System of a Down with their 2006 GRAMMY® for Best Hard Rock Performance winning single “B.Y.O.B.”

When the house lights go down this fall, a new generation of guitarists, drummers and fearless frontmen will come together and rock with Guitar Hero World Tour. The latest installment in the #1 best-selling video game franchise of 2007, Guitar Hero World Tour transforms music gaming by expanding Guitar Hero’s signature guitar gameplay into a cooperative band experience that combines the most advanced wireless instruments with new revolutionary online* and offline gameplay modes including Band Career and 8-player “Battle of the Bands,” which allows two full bands to compete head-to-head online for the first time ever.

Music creators will also be able to share their recordings with their friends online through GHTunesSM where other gamers can download and play an endless supply of unique creations.
