Mario Kart World Update 1.5.0 - Patch Notes Review and Gameplay Changes (2026)

A new update has arrived for the highly anticipated Nintendo Switch 2 launch title, Mario Kart World, and it's packed with some important modifications and bug fixes that players will want to know about.

This latest patch, officially labeled version 1.5.0, introduces the exciting feature of team racing in the Knockout Tour mode, allowing you to collaborate with friends in multiplayer sessions, whether you are playing over the internet or through a local wireless connection. Additionally, support for the Polish language has been added, making the game more accessible for Polish-speaking players.

However, amidst these updates, there's a curious detail that stands out in the patch notes—what seems to be a mistake regarding Kamek, a character not currently playable in Mario Kart World. The patch notes mention a fix related to an issue when using Kamek on Choco Mountain, which many players have pointed out is likely intended to refer to the Kamek item rather than the character itself.

In comparison to the previous 1.4.0 update released late last year, which significantly revamped various track layouts and sparked excitement among fans for future enhancements, this update feels somewhat less substantial. The 1.4.0 update not only modified the game’s open world but also laid the groundwork for speculation about further developments on the horizon.

To date, Nintendo has primarily focused on refining the gameplay experience of Mario Kart World without introducing any additional downloadable content (DLC), whether free or paid. As we look ahead, it remains to be seen how the game will evolve as the Switch 2 continues its lifecycle.

For those interested, here are the complete details of the changes included in the recent update, version 1.5.0, released on January 21, 2026:

Mario Kart World: Version 1.5.0

General Updates:

* Team racing has been added to Knockout Tour for multiplayer play, both online and locally.

* The game now includes support for the Polish language.

Note: You can adjust your preferred language by navigating to the “Language” setting located in the “System” menu within “System Settings.”

Fixed Issues:

* Resolved a glitch that caused the game to unexpectedly end while playing as Kamek on Choco Mountain.
