Rock Band 4 is the fourth game in the Rock Band series released five years after the previous main title Rock Band 3 . It continues the concept of the earlier games where players simulate playing music using peripherals designed as instruments to mimic playing the lead and bass guitar and drums, and singing the vocals to songs. Unlike the contemporary Guitar Hero Live , it has backwards compatibility for the instruments and content of the previous games in the same console family. The wireless guitar and drum controllers from the PS3 and Xbox 360 versions of previous Rock Bands can be used.
The gameplay is identical to the earlier games and the visual style is still based on animated characters and environments. One or more players use the instruments and microphone to play and sing through songs by following the cues on the screen. The score is based on accuracy. Certain sections are marked with coloured notes. When these are completed successfully, an Overdrive meter is filled. When sufficiently full it can be activated to double the score multiplier for a short while.
Freestyle solos are a new feature for the game. There are sections with solos for individual instruments where there are no prompts on the screen to follow. The player is entirely free to improvise, but to score there are a few general rules to follow. Using the guitar a blue colour shows the upper buttons need to be used and an orange colour the bottom ones.
In the main career mode a starting band is introduced who needs to make it to the top. Instead of just completing songs to progress, the game presents various options for gigs that hold certain risks and rewards, from the attendance of fans based on the chosen region to the amount of money that can be earned and the opportunities it opens for the future career.
The base game contains 63 tracks, with both new ones and some that were previously available as DLC for earlier games. The game also features a new mode called "shows", as a series of songs broken up in sets. Players can vote on the songs between or during parts of the song when their instrument is not active.
Rock Band 4 was released on October 6, 2015 for the Playstation 4 console and is part of the Action & Adventure genre. It can be purchased as a standalone game or as a bundle with additional instruments.
