bass guitar co-operative play track. Bonus songs There are 24 bonus songs in the PlayStation 2 version of Guitar Hero II and 2 additional songs for the Xbox 360 version. All bonus songs are unlockable by using in-game money within the game's store. Once purchased, they are playable in quick play, competitive, and co-operative modes. The song "Raw Dog" by The Last Vegas was selected as part of the "Be a Guitar Hero" contest for the release of Guitar Hero II. All bonus songs are master recordings, and where marked, include rhythm guitar rather than bass guitar tracks. Downloadable content The Xbox 360 version of the game allows for the use of downloadable content available through Xbox Live Marketplace. These are typically released as packs of three, or as single song. These packs include songs from the original Guitar Hero for the PlayStation 2. Additional packs consist of songs that have not been featured in Guitar Hero before, and are masters, even though some are indicated as covers in the game. As of April 1, 2014, these songs are no longer available in the Xbox Live Marketplace. References General Specific External links Official website II
