Nintendo Switch 2 launch title Mario Kart World has just received a meaty update that finally adds custom item rules, and tweaks a long list of course layouts.
Fans of Mario Kart World’s brilliant soundtrack, which is filled with toe-tapping remixes and fresh renditions of classic Nintendo tunes, will also now be able to see the name of each melody, and the game it was originally featured in.
And in other tweaks, there seems to be further acknowledgement that fans simply haven’t warmed to the game’s so-called intermission tracks, a fan term for World’s frequent preference that you spend time racing between discrete courses, rather than on them. In all races heading toward Koopa Troopa Beach, players will now get to play two laps once they arrive, rather than just one.
This patch’s biggest addition is the ability to set custom item rules when playing VS Race, Balloon Battle and Coin Runners, or when setting up an online play Room. As in previous Mario Kart games, this lets you disable certain items you don’t like (that flipping Lightning…) or create item sets tuned towards mayhem (only Blue Shells).
Numerous other quality of life tweaks are included — all listed below — including a shortened time for some coin and Dash Food regeneration. My favorite note, however, is this one: “Made it so the player cannot use a second Boo while already using a Boo, when holding two Boos.”
The full patch notes lie below:
