As Ubi explains, "Playable maps include Teensies in Trouble and A Toad Story, along with their Invasion Mode counterpart level, and a fan-favourite musical map themed to the song 'Black Betty'.
"The demo will also include access to the Gallery of Heroes where players can swap costumes of their character, and various trailers for the game."
Meanwhile, we have two new Rayman Legends videos below; the first a gameplay playthrough of the 'Gloo Gloo' music level, and the second a developer interview with technical director of art Benjamin Mouret, who discusses some of the additional content that's been built into the game thanks to its lengthy delay.
