10 Secret Levels In Iconic Video Games You Totally Missed

5. Super Smash Bros. - Mushroom Kingdom

Nintendo struck gold when they realised they could throw all their loveable characters into one melting pot of special moves and iconic soundbites. As such there have been a ton of SSB games across all their consoles, but its the original N64 version that has one of the best secrets; a Mario-influnced Mushroom Kingdom level. To get it - and there have been many variations on the 'right' way to do this - so let me know in the comments if I'm still wrong - you need to first beat the 'campaign' single player with all eight original characters, then head over to Vs. Mode and clock each level once again, with anyone. Difficulty doesn't matter and doesn't need to be consistent in terms of going through the roster left-to-right, you only need to do each of these things once, and afterwards the Kingdom level will appear in the stage select screen complete with themed music, some warp pipes and one of the best layouts for battle in the franchise.
