Just Dance 4 is the fourth main game in the dancing series where players are rated for their ability to mimic dance routines to popular songs. On the Xbox 360 platform movement is tracked through the Kinect peripheral. For other platforms, such as Wii and PlayStation 3, movement is tracked through different peripherals like the Wii Remote or the PlayStation Eye camera with optional support for the Move peripheral.
Compared to the previous version, the difficulty levels have been removed as well as the option to do a quick dance to get through a song more rapidly. Also axed are various game modes such as Simon says, medley, speed shuffle, playlists, just create and 8-player. It is also no longer possible to create custom dance routines. New to the series are the dance quests where six missions are provided for a single song. By completing them mojo points, the in-game currency, are earned. On all platforms except for Xbox 360 players can create dancer cards as a profile for favourite songs, best scores and completed challenges.
New features include sweat mode, which counts calories and includes fitness-like exercises with warm-up and cool-down moments. Other game modes are the battle mode and dance mash-up mode. For platforms with a camera, there is an autodance feature that records moments of gameplay and mixes them into a video. The base game contains about 50 tracks, with variations based on the platform and the region.
Additional songs are offered as DLC for all platforms. Some of the included artists are Christina Aguilera, Justin Bieber, Carly Rae Jepsen, Rihanna, Jessie J, Flo Rida, Carrie Underwood, Elvis Presley, Ricky Martin, Nelly Furtado, Rick Astley, Britney Spears, and Skrillex.
