Mario Tennis Fever Brings Back the Series With Fever Shots, Talking Flower Commentary and More

Mario Tennis Fever adds Goomba, Piranha Plant, and Baby Wario.

Nintendo is bringing the Mario Tennis series back with Mario Tennis Fever, launching Feb. 12 exclusively for the Nintendo Switch 2. The new entry leans into “over-the-top tennis mayhem,” while keeping familiar shots like topspins, slices, and lobs.

The game lists 38 playable characters, which Nintendo calls the most in series history. Newcomers include Goomba, Nabbit, Piranha Plant, Baby Wario and Baby Waluigi.

Fever Rackets turn rallies into chaos

The biggest hook is the new Fever Rackets system. Players can equip one of 30 rackets, each with its own gimmick, then build a Fever Gauge to fire off a Fever Shot. Nintendo says opponents can try to return a Fever Shot before it lands, sending the effect back instead.

Nintendo highlights several racket effects in its overview. The Ice Racket can freeze parts of the court, while the Mini Mushroom Racket can shrink opponents. The Shadow Racket creates a duplicate to confuse the other side.

New modes, returning favorites

Nintendo is stacking the package with modes aimed at both new players and veterans. Trial Towers asks players to clear challenge runs as they climb toward the top.

Mix It Up and Wonder Court Matches

Mix It Up mode changes the rules mid-match. Ring Shot rewards precision by scoring through rings, and Forest Court Match can expand the court by feeding tennis balls to Piranha Plants.

Wonder Court Matches add “Wonder Effects” inspired by Super Mario Bros. Wonder. Nintendo says those effects are meant to keep players guessing.

Tournament, online play and Swing Mode

Tournament mode returns with a new twist: play-by-play commentary from a Talking Flower. Online options include Online Room for casual rulesets and Ranked Matches for competitive play.

There is also Swing Mode, which uses Joy-Con 2 motion controls for racket-style play. Nintendo describes it as a gentle swing approach for a more physical feel.

Adventure mode adds a story hook

For solo players, Mario Tennis Fever includes an Adventure mode campaign. Nintendo says “mysterious monsters” turn Mario, Luigi, Princess Peach, Wario and Waluigi into babies. The group must re-master their tennis skills to return to normal.

That premise also marks a notable shift from the last Switch entry’s approach. Mario Tennis Aces launched in 2018 and also featured an Adventure mode, though its focus leaned more on mission play than a transformation storyline.

GameShare support and new Joy-Con colors arrive the same day

Nintendo says the game supports GameShare, letting one Switch 2 owner share a local session with up to three nearby players. Those guests can join from a Switch 2 or even a Nintendo Switch system, but only for the active session.

Nintendo also announced new Joy-Con 2 colors, Light Purple and Light Green, arriving Feb. 12.

Mario Tennis Fever is listed at $69.99 with an estimated 10 GB file size. Pre-Order Here.
