You can pre-order the Mario Kart 8 Deluxe Booster Course Pass now for $25. Alternatively, if you’re a Nintendo Switch Online + Expansion Pass subscriber, you can grab the new courses for “free.” Here’s a bit more official detail on the DLC… I’ll admit, as one of the few who bought MK8 on the Wii U, I’ve been holding out on the Deluxe version, but I think they may have dragged me back in with this. Mario Kart 8 Deluxe is available now on Nintendo Switch. The first wave of the Booster Course Pass kicks off on March 18.
