Nintendo’s latest Mario Kart World patch nerfs the Boomerang Flower, adds “No COM” and “Mushroom Only” options, and fixes major bugs. Here’s what’s new in version 1.2.0.
Boomerang Flower Nerfed in Mario Kart World 1.2.0 Update — Aim Better, Drifters
Nintendo just dropped the 1.2.0 patch for Mario Kart World, and if you’re a Boomerang main… oof, this one’s gonna sting.
The update, released July 29, 2025, is packed with tweaks and bug fixes, but the headliner? The Boomerang Flower got its homing powers nerfed. So yeah, no more lazy tosses and clutch hits — you’re gonna have to actually aim now. Sorry, not sorry.
But that’s not all this patch brings. From smarter VS Race rules to a full-on bug extermination campaign across fan-favorite tracks, 1.2.0 is more than just a balance update — it’s a solid quality-of-life refresh.
Patch Highlights: What’s New, What’s Nerfed
🪃 Boomerang Flower Hits a Wall
Let’s be real — the Boomerang was kinda cracked. Not only could it spin opponents out, but it also had built-in homing like it was auditioning for a heat-seeking missile job. Now, the homing is dialed back, which means more whiffs if you’re not on point. High-skill Boomerang players, this is your time to flex.
New VS Rules: No COM and Mushroom Mayhem
Sick of CPU racers clowning on your clean drifts? You can now turn them off in “VS Race” for both single player and multiplayer with the new “No COM” option. Also added: “Mushrooms Only” — perfect for chaotic speed boosts and no blue shell drama.
Add that to some lap-type course prioritization and weaker CPU AI in non-battle modes, and we’re getting closer to that player-first vibe.
Gameplay Tweaks & QoL Buffs
- Spectator Mode Boosts: You can now pick who to watch during Knockout Tour and Balloon Battle matches — a win for anyone who’s tired of staring at random Waluigis doing donuts.
- Time Trial Glow-Up: Download ghost data? Now you can instantly hit “View Replay.” Finally.
- Camera Memory: Multiplayer cameras now remember your zoom/cursor settings until you quit the game. Neat touch for streamers and content creators.
- Free Roam Bling: Collect all the stuff on the map and boom — color-coded flex for your efforts.

Bug Fixes: The Long Scroll of Justice
Nintendo went full pest control mode on this one. A ridiculous number of bugs have been fixed — from characters floating midair to Bullet Bills taking you straight into the void. Here’s a TL;DR of the juicy ones:
- Fixed Bullet Bill chaos across multiple maps (no more surprise pit stops).
- Cleaned up glitchy item behavior, like items switching mid-use or dash pads not working online.
- Track-specific issues on fan-faves like Sky-High Sundae, Dino Dino Jungle, Bowser’s Castle, and Wario Shipyard were fixed — so less getting stuck, and more actual racing.
- Smart Steering improvements so it doesn’t send you flying off cliffs anymore. Helpful!
Honestly, if you’ve ever shouted “BRO WHAT WAS THAT?!” while flying off the track for no reason — this patch might’ve fixed it.
What This Means for Competitive Play
This patch feels like Nintendo starting to tune Mario Kart World for more competitive depth. Boomerang nerf = higher skill ceiling. New rules = more control over races. CPU nerfs = less random nonsense. If you’re grinding Time Trials or Knockout Tours, you’re probably already feeling the impact.
Pro tip: If you’re practicing lines, take advantage of the more predictable item behavior. With less RNG chaos, it’s a good time to level up.
Final Lap Thoughts
Mario Kart World 1.2.0 isn’t just a balance patch — it’s a sign Nintendo’s actually listening. Between the Boomerang nerf, new race options, and bug fixes that smooth out the weirdest ride moments, this update brings some much-needed polish.
Just make sure your throws are clean now — no more heat-seeking Boomerang bailouts.
Summary:
- Boomerang Flower nerfed — less homing, more skill required.
- New VS Race rules — “No COM” and “Mushrooms Only” added.
- Bugs fixed across tons of tracks — Bullet Bill glitches, stuck characters, broken shortcuts, you name it.
- Online play now requires 1.2.0, so update before hopping in.
