Mario Tennis Fever Serves Up 38 Characters and Fever Rackets for Nintendo Switch 2

Nintendo and Camelot Software Planning are bringing the heat to the court with Mario Tennis Fever (マリオテニス フィーバー), launching February 12, 2026 exclusively for Nintendo Switch 2. Priced at $69.99, this latest entry in the beloved tennis series delivers the most ambitious roster and gameplay innovations the franchise has ever seen.

The Largest Roster in Series History

Mario Tennis Fever features 38 playable characters, the most in series history. Veterans like Mario, Luigi, Peach, Daisy, Rosalina, Pauline, Wario, Waluigi, Bowser, Donkey Kong, Yoshi, and Boo return alongside fan favorites like Diddy Kong, Chain Chomp, Petey Piranha, and Dry Bowser.

The roster welcomes several exciting newcomers to the tennis court. Goomba makes its playable debut in the series, joined by the mischievous Nabbit, the adorable Lumalee, and Light Blue Yoshi. The baby character lineup expands with Baby Wario and Baby Waluigi joining Baby Mario, Baby Luigi, and Baby Peach. Each character features unique playstyles, from power hitters to technical players and speed demons.

Revolutionary Fever Racket System

The game's signature innovation comes in the form of Fever Rackets, a collection of 30 special rackets that fundamentally transform how tennis is played. These aren't mere cosmetic items—each Fever Racket grants unique abilities that can turn the tide of any match.

The Ice Racket freezes the court surface, causing opponents to slip and struggle with movement. The Bullet Bill Racket adds explosive power to shots. The Mini Mushroom Racket shrinks opponents temporarily, while the Thwomp Racket creates devastating ground-pound effects. Shadow and fire-themed variants round out the collection. With 30 different rackets to collect and master, players can develop countless strategic combinations tailored to their playstyle and character choice.

An Adventure Across the Islands

Mario Tennis Fever features a full Story Mode that takes players on an unexpected journey. The adventure begins when Mario and his friends discover themselves transformed into babies by an unknown creature on a mysterious remote island. Having lost their tennis skills, the baby heroes must learn the sport from scratch while battling monsters to restore their normal forms.

Boss encounters include challenging matches against Petey Piranha and King Hisstocrat. This narrative-driven mode provides hours of single-player content beyond traditional exhibition matches. As players progress, they'll unlock new characters, Fever Rackets, and cosmetic items that carry over to other game modes.

Courts and Gameplay Features

Mario Tennis Fever includes 14 unique courts spanning iconic locations from the Mushroom Kingdom and beyond. The game incorporates Wonder Flower mechanics from Super Mario Bros. Wonder, adding unpredictable transformations and effects during matches.

The multiplayer suite includes online ranked matches, casual play, and local wireless support for up to four players. Swing Mode lets players use Joy-Con 2 controllers as rackets for motion-controlled gameplay. The game leverages Nintendo Switch 2's enhanced hardware for smoother visuals and responsive controls.

Courts and Visual Showcase

Mario Tennis Fever takes full advantage of Nintendo Switch 2's hardware capabilities to deliver the most visually stunning Mario Tennis game to date. Courts feature dynamic elements and environmental interactions.

From Peach's Castle gardens to Bowser's volcanic fortress, each venue offers unique aesthetics and potential gameplay hazards. Some courts feature special conditions that interact with Fever Racket abilities, encouraging players to adapt their equipment choices to the arena.

Legacy of Camelot

Developer Camelot Software Planning brings decades of Mario Tennis expertise to this latest entry. The studio has helmed the series since Mario Tennis on Nintendo 64 in 2000, consistently delivering tight gameplay mechanics and engaging content.
