A free update for Mario Tennis Fever has been released, adding a new court, racquet and Mix-It-Up mode based on the Super Mario Galaxy games, as well as adding online GameShare via GameChat.

Update 1.1.0 for Mario Tennis Fever is out now, and it’s a pretty good batch of new content. The new Galaxy Court is themed around Mario Galaxy visually, but also gives balls a higher bounce to mimic lower gravity of its smaller celestial bodies. Then there’s the new Black Hole Racket, which can create black holes with a Fever Shot that can suck opponents right in.

The Galaxy Court Match is added as a new mode, which introduces one of three Prankster Comets, which can summon shadowy doubles, speed everyone up, or a sudden death mode where body hits will immediately knock a character out of the game.

Perhaps the best addition, though, is GameShare now being able to work online via GameChat. While this requires everyone to have a Switch Online membership for GameChat, it does mean that four people can play online using one copy of the game (I would just be mildly wary about latency in this scenario).

Here’s the full Mario Tennis Fever v1.1.0 patch notes:

Added “GameShare” and ”Play via GameChat”

Added functionality to play the game with friends on GameChat who don’t have the game.
In “Play via GameChat,” you can play tennis matches with swing controls in addition to tennis matches with button controls and games in Mix It Up.Note: A Nintendo Switch Online membership is required to use GameChat.

Added a New Fever Racket, the “Black Hole Racket”

The new “Black Hole Racket” Fever Racket has been added which causes a black hole when the Fever Shot hits the ground.
The black hole it causes has the effect of pulling players who are nearby into the black hole when it gets large.
Your HP Gauge will take damage if you get close to the black hole. If your HP reaches 0 due to the black hole and you are knocked out, you will be sucked into the black hole.
Black holes do not have the effect of drawing in incoming balls.

Added a New Court, the “Galaxy Court”

A new court has been added based on Super Mario Galaxy.
The court is made on a distant planet, and although the ball speed isn’t particularly fast, balls have a high bounce.
The court has a different shape depending on whether you are playing Free Play or Ranked Match matches, or in Special Match.

Added a New Special Match, “Galaxy Court Match”
