Harmonix has just launched Rock Band Rivals, an expansion to Rock Band 4 that finally introduces on line multiplayer as well as a bunch of band focused features.

Rock Band Rivals introduces two all-new game modes as well as multiple new venues and Rock Shop items to Rock Band. Marking the much-anticipated return of online play to Rock Band

In Rivals Mode, players band together to form crews of up to ten people to take on other crews around the world in a structured and ongoing series of uniquely themed gameplay challenges.

Rockudrama is an all new campaign mode and the world’s first playable music documentary. Featuring a mix of live-action video, in-engine footage and classic Rock Band gameplay, Rockudrama dynamically tells the story of your band’s epic, and often hilarious, rise to fame.

With the free Rock Band Rivals Companion App, players will be able to coordinate with their crews no matter where they are. Within the app players can access details about the weekly challenge, manage their crew roster, message other members of their crew and monitor their crew’s progress during weekly challenges.

Rivals is launching with a new bundle that includes the game, drum kit, microphone, and a Rock Band Wireless Fender® Jaguar® Guitar Controller for $199.99 USD. The smaller bundle includes the game and the guitar for $89.99. For current owners of Rock Band 4 you can purchase a standalone digital download of rivals for $29.99. Rock Band Rivals is now available for Xbox One and PlayStation 4.
