Guitar Hero Live is an entry in the Guitar Hero series and a reboot of the franchise after the hiatus following Guitar Hero: Warriors of Rock in 2010. The core concept is identical: players use a plastic guitar peripheral to play the guitar sections of songs by following the cues on the screen and pressing the matching buttons on the instrument in time. Unlike the contemporary Rock Band 4 , there is no backwards compatibility with instruments of content from earlier games. The largest difference compared to earlier titles is in the presentation. In the Guitar Hero Live mode, each song is now played from the perspective of the guitarist during a real-world concert setting using full motion video footage. The gameplay involves following the notes on a scrolling "highway" on the screen with the video playing behind it. There are three lanes and different colors to differentiate between the top or bottom row on the instrument. The game has multiple difficulty levels, including casual where only one row of buttons is used. Power chords generally use the top row. Hero Power can be collected by correctly playing a specific series of blue notes on a track, which can be unleashed at any time to please the crowd and save a performance.
The first part of the game is called Guitar Hero Live , an offline story/career mode where the player becomes a guitarist for different fictitious bands playing existing tracks from popular bands on a number of fictitious festivals. Each band plays a set of three or four songs on different stages of the festival and during the day or at night. This portion of the game contains 42 different tracks for different genres.
The second part of the game is the online Guitar Hero TV mode, which offers multiple channels that stream songs all day long and most of the time different from those in the Guitar Hero Live mode. The genre switches after some time. This mode can be played in split-screen multiplayer, and players can earn points and credits by completing songs. In-game credits can be used to access a Premium channel with rotating challenges and asynchronous multiplayer against other players for the best scores.
Guitar Hero Live was released on PlayStation 4 on October 23, 2015 . The game is sold as a bundle with one or two guitar controllers and also as a retail package. It also has an in-app purchase option for iOS mobile platform where the game itself is downloaded for free with a $50 in-app purchase to unlock the full digital content.
