A New Super Mario Bros 2 DLC pack is so hard that Nintendo have called it the Impossible Pack. It's available in the US from today and will be released alongside a Mystery Adventure Pack.
The Impossible Pack has a difficulty level that's beyond 5 Stars but it doesn't feature any coins of power-ups. New Super Mario Bros 2 is all about collecting coins but the amount of cash you receive in this pack adds up to the amount of time you have left at the end of each level.
The first level of this pack has you attempting to swim past Cheep Cheeps, jumping on small platforms and dodging birds and Spineys.
For those who can't handle the Impossible Pack, there is a Mystery Adventure Pack which has a three star difficulty level. The coins are back for this course as you attempt tp collect as many as possible while looking out for hidden paths.
Each pack costs $2.50. Here's a video:
