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.

The first game the company developed under Activision's ownership was "DJ Hero" (2009), a spin-off of the "Guitar Hero" series, in which players used a turntable-based controller to mimic the actions of a disc jockey across numerous songs. The title was considered successful, and they completed "DJ Hero 2" the following year, though around that time, the rhythm game genre was suffering from a glut of releases and was in decline, and Activision had decided to end further production of any "Guitar Hero" title. The company had to lay off some employees during this time, but still were financially viable with success of "Sing Party" (2012). As "Sing Party"s development was wrapping up, Activision approached FreeStyleGames to have them consider how to reboot the "Guitar Hero" franchise. FreeStyleGames developed a new guitar controller atypical of ones that has been created to that point, and crafted a different approach towards presenting the game to players through a first-person perspective full-motion video. This work culminated in "Guitar Hero Live" (2015), the first new "Guitar Hero" title for the eighth generation of video game consoles.
