IGN reveals a secret, final level for those who have collected all five stars on their file.
So you have your copy of Super Mario 3D Land. Many of you have probably beaten it already, some of you have even collected all of the Star Coins.
But that's not where the story ends. There's an extra level you unlock if you earn yourself all five stars on your file. You get one for beating Bowser. You get two for beating each level as both Mario and Luigi. You get the fourth for getting the golden flagpole in all levels, and the fifth for getting all the star coins.
Do all that, and your reward is access to the special, secret level shown in the video below. Needless to say, if you're anti-spoilers, by no means should you watch this video. If you watch it anyway, don't come crying to us.
Sadly, IGN video's cant be embedded and the clip hasn't made it onto Youtube yet so follow the link below to see the video.
