Nintendo has released a new Super Mario 3D World trailer showing ten things you'll want to see and do in the upcoming Wii U game.
The video shows a number of new features, including touch screen and microphone interactivity, speed run stages and special Captain Toad levels.
However, it also reveals one of the game's hidden unlockables - a fifth playable character who joins Mario, Luigi, Toad and Peach.
For the sake of keeping the spoiler a secret we won't reveal who it is, but you can find out by watching the video below - however, we should also warn that the character in question features in the video thumbnail so you shouldn't scroll down at all if you don't want the secret ruined.
Nintendo has confirmed a Super Mario 3D World release date of November 22 in the US and November 29 in Europe and Australia.
Last month, Nintendo president Satoru Iwata suggested Super Mario 3D World will help drive Wii U hardware sales.
In CVG's most recent Super Mario 3D World preview we said "there's every likelihood that this will be the best Nintendo game since Galaxy - and maybe, just maybe, it'll provide enough consistent moments of magic to surpass it."
