Mario Kart 8 Deluxe – Booster Course Pass

The Mario Kart 8 Deluxe – Booster Course Pass (also referred to as the Mario Kart 8 Deluxe – Booster Course Pack) is a DLC expansion pack for Mario Kart 8 Deluxe, announced during a Nintendo Direct held on February 9, 2022. The pack includes 12 additional cups, for a total of 48 additional courses, all of which are remastered versions of courses from past Mario Kart games, including Mario Kart Tour. The courses use their designs from Mario Kart Tour, with the exceptions of Wii Coconut Mall and  DS Shroom Ridge, which are currently absent from said game. The pack marks the longest gap between the original release of a Mario game and the release of its DLC, releasing nearly five years after Mario Kart 8 Deluxe did.

The pack is set to be released in six waves by the end of 2023, with the first releasing on March 18, 2022. It can be purchased on its own, but is also included in the Expansion Pack subscription for the Nintendo Switch Online service.

Courses
Each of the six waves features two cups, each with four courses (for eight courses per wave).
