Guitar Hero
In 2015, Activision announced the first new title to the series in 5 years, "Guitar Hero Live", released in October 2015. The title is considered a reboot of the series, with development being performed by FreeStyleGames, who had developed the "DJ Hero" games previously. As of December 1, 2018, Activision disabled the GHTV servers for Guitar Hero Live, reducing playable content from approximately 500 songs to 42 on disc tracks.
Guitar Hero: Warriors of Rock
Sales of "Guitar Hero: Warriors of Rock" were weaker than those of "Guitar Hero 5", with combined sales of the game and "DJ Hero 2" through the end of 2010 being 63% lower than the sales of "Guitar Hero 5", "DJ Hero" and "Band Hero" through the end of 2009. Initial shipments of "Warriors of Rock" were also bundled with a copy of Soundgarden's compilation album "Telephantasm"; based on its distribution with copies of the game, "Telephantasm" became the first album to receive a Platinum certification from the Recording Industry Association of America based on distribution alongside a video game. As a result of the underwhelming sales, also credited to the oversaturation of the music game market, the "Guitar Hero" franchise was ultimately shuttered until the 2015 unveiling of a reboot, "Guitar Hero Live".
