Super Mario 3D World + Bowser's Fury

Super Mario 3D World + Bowser's Fury is an upcoming expanded port of Super Mario 3D World for the Nintendo Switch, set to be released on February 12, 2021 as part of the 35th anniversary of Super Mario Bros.

The game will also support local wireless and online play, both being absent from the original game.

Changes from the original game

 * The player's movement speed has been increased, thus allowing for courses to be cleared quicker.
 * Character movement is no longer restricted to only eight directions.
 * Players can climb higher when in their Cat forms, compared to in the original game.
 * The game has amiibo support, with Cat Mario and Cat Peach amiibo figures launching alongside the game.
 * Player characters are now able to roll in midair.
 * The UI for lives and coins lacks the "×" icon between the image and numbers, while the shadows have been removed.
 * Up to four players can team up or race together in multiplayer mode, which supports both local wireless and Nintendo Switch Online connections.

Bowser's Fury
Bowser's Fury is a new mode to this game. It stars Mario and Bowser Jr. working together to save an unnamed area from Bowser who appears to have been corrupted by some unknown dark power.

Features

 * Bowser Jr. makes an appearance as an AI controlled ally, using his Magic Paintbrush to attack enemies or discover hidden secrets.
 * New cat variations of enemies are featured, though unlike Cat Goombas and Cat Bullet Bills, their cat appearances are only aesthetic changes, not gaining any new abilities. Enemies and bosses like this include:
 * Cheep Cheeps
 * Spikes
 * Pom Pom
 * Piranha Plants
 * Conkdors
 * Boomerang Bros
 * Goombas, though they behave like regular Goombas and keep their brown color scheme instead of having yellow fur and the diving ability.
 * There is a giant variation of the Super Bell with whiskers, which turns Mario into a giant variation of Cat Mario, slightly resembling a lion.
 * This mode introduces an unnamed new species of cat characters.
 * When Bowser attacks the level, a darker variation of these cats make an appearance trying to attack Mario.
 * Rather than collecting Green Stars, the player collects medals that resemble a cat's head. Additionally, instead of a Goal Pole, there are sun-based collectibles with a cat's face on them, similar to Power Stars, Shine Sprites, and Power Moons.
 * The animation that Mario does when collecting the cat-sun based collectibles resembles the animation when collecting a non-story related Power Moon in Super Mario Odyssey.
 * A giant, dark, version of Bowser appears as the villain. He will terrorize the level by breathing fire.
 * The area appears to be sandbox-styled similar to Super Mario Odyssey.
