Super Smash Bros Wii U was one of the most anticipated games before its release. If Amazon Best Selling Games of 2014 is any indication, the game lived up to the wait as it's the 19th best-selling game of the year.

Super Smash Bros Wii U has secrets that, if accessed, will reward you with some pretty nifty bonuses. This includes the ability to unlock and play hidden characters and levels. Some of the fighters are classic Nintendo characters that go all the way back to the release of the first Nintendo console roughly 30 years ago.

To unlock these characters and stages, just perform the associated task below.
