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 Mobile series
Guitar Hero Mobile is a series of rhythm video games in the "Guitar Hero" series, adapting the normal console-based gameplay which uses a guitar-shaped controller to match notes of popular rock music songs to work with the face buttons on advanced mobile phones, including BlackBerry devices and those supporting the Windows Mobile platform. The first three games in the series—"Guitar Hero III Mobile", "Guitar Hero Backstage Pass", and "Guitar Hero World Tour Mobile"—were developed by MachineWorks Northwest LLC and published by Hands-On Mobile, while a mobile version of "Guitar Hero 5" was developed by Glu Mobile. The series has proven to be popular; the "Guitar Hero III Mobile" game has been downloaded more than 2 million times, and over 250,000 songs are played each day across the series.
