The game comes with 66 songs on disk, with thousands more available to download in paid DLC packs. Like its predecessor, the games main feature is that it allows players to plug in virtually any electric guitar or bass guitar and play along via the use of a USB adapter - removing the need for any proprietary controller like other music games such as Guitar Hero. It is a followup to the 2011 game Rocksmith, but has been described as a replacement to the original game rather than a sequel. Rocksmith 2014 is a music video game produced by Ubisoft.
