Nintendo continues its robust post-launch support for Mario Tennis Fever, today rolling out the game's second major patch, Version 1.0.2. Available now, this update primarily targets recalibrating the game's competitive meta through significant adjustments to character specifications, shot behavior, and the efficacy of various Fever Rackets. These changes aim to foster a more diverse and balanced gameplay experience, addressing community feedback since the title's launch on Nintendo Switch 2 last month. The 1.0.2 patch, detailed via Nintendo's official support channels, is a critical step in refining the game's competitive landscape. It introduces a series of character buffs and nerfs alongside modifications to key power-up rackets, signalling a responsive approach from the development team to balance early meta dominance.
