Super Mario Odyssey just got multiplayer support for ten players thanks to a rather ingenious modder. The person behind the project, CraftyBoss, released the unofficial expansion to players with a digital copy of the game and a specially modified Nintendo Switch. CraftyBoss has apparently been testing the mod since around this time last year.

“Have fun exploring kingdoms with friends, playing game modes, or beating the game as fast as possible! This mod is still early in development, so expect bugs and unrefined aspects as we work hard to improve it and make the mod as polished as possible,” CraftyBoss remarked. The modder also released a short gameplay video.

Players are able to explore each Kingdom in the game while syncing their progress after collecting a Moon. Since character customization is also supported, players are able to change outfits at any point in time, including into some that were previously exclusive to the 2D parts of Super Mario Odyssey.

The mod allows players to “explore Kingdoms together with up to ten people,” enjoy full “costume models syncing,” and a “custom configuration menu accessible by holding ZL and selecting any option in the Pause/ Start menu.” CraftyBoss offers “support for custom game modes,” but notes how this remains a “work in progress.”

When it comes to custom game modes, these include a form of Hide and Seek in which players pick a seeker at the beginning of each round and a Kingdom in which to hide. Scores are tallied in the form of a timer at the top right side of the screen. This increases until a player is discovered at which point they respawn as a seeker. The round is won by whichever player manages to accumulate the most time.

Super Mario Odyssey was released on October 27, 2017 to rave reviews on the part of both critics and players. The game is often cited as being one of the best entries in the franchise. Super Mario Odyssey has won several awards and sold more than 23 million copies.
