The Nintendo Switch 2 is finally here, and with it, the console’s biggest launch title, Mario Kart World. Expectations are sky-high for the latest entry in the 33-year-old racing series, which carries the weight of a new console’s fortunes on its shoulders.

Mario Kart World's open-world doesn't work as well as intended, but the new battle royale style Knockout Tour delivers a great new way to play.

Spotted by IGN, an account on X called Ninjinaut showcased the Mirror Mode Easter egg in Free Roam for Mario Kart World. The video sees Baby Rosalina jumping into the window, which is a direct callback to Super Mario 64's mechanic for accessing new worlds.

Nintendo aims to deliver on ideas the developers have been holding onto for a while, creating a game that’s bigger and more chaotic than ever before, without skimping on the little details that give the brand its spirit.
