Thought you’d done all there was to do with New Super Mario Bros? You rocked Bowser Jr’s face off, collected all the Star Coins, and figured you were the cat’s pajamas? Think again, young whipper snappers. Until you’ve played New Super Mario Bros’ recently discovered Challenge Mode, you’re just a weird kid wearing your mom’s kitten-patterned nightie.

Gamers who’ve already finished the game will be able to access this secret Challenge Mode by hitting Start in the world map and pushing the following combination of buttons during the Start Menu:

L R L R X X Y Y

So what sort of obstacles does the game set against you for this challenge mode? Tougher enemies and tighter level design? A white, disembodied head that doesn’t just chase you in the game, but stares at you from outside your window while you sleep at night? Having to beat a castle while your mother bangs on your bedroom door, yelling at you to give back her nightgown?

Unfortunately, it’s nothing too fancy like the examples above. Challenge Mode puts a forced scroll on all the levels just like with the original Super Mario Bros. game. Players will no longer be able to backtrack, picking up coins and power-ups that were left behind.

With new secrets being found almost two months after the game’s release, who knows what other mysteries are still waiting to be found. Hot Koopa Troopa Mod?
