Unleash a new type of court chaos in Mario Tennis Fever on Nintendo Switch 2. This entry introduces the game-changing "Fever Racket" system, allowing you to build up a meter and unleash devastating "Fever Shots" that can cover your opponent's court in ice or shrink them with Mini Mushrooms. In the all-new Adventure Mode, a curse transforms Mario and friends into babies, forcing them to relearn their skills and defeat monsters to return to normal. Master new footwork, challenge the "Trial Towers," or take on the chaotic "Mix It Up" mode where Wonder Effects can change the rules at any moment.
