Arms Update Out Now For Nintendo Switch, Here's What It Does

Switch's Arms has been updated with lots of tweaks.


Nintendo's Switch fighting game, Arms, has received a new update, and version 2.1 adds new training exercises and changes a bunch of fighters. There are also lots of balance changes not specific to any one fighter, such as the rush gauge filling slower when your attacks miss.

In terms of specific tweaks, plenty of fighters and Arms have been buffed. Master Mummy and Mechanica now have faster movement, as do the Boomerang and Coolerang Arms. There also a few Arms that have been nerfed to some extent, such as Bubb and (ironically, given the name) Buff--they now extend slower. Take a look at the full list of changes, via Nintendo, at the bottom of this article.

Now Playing: ARMS Video Review

Arms launched in June to a positive critical reception. Nintendo has continued to support the fighting game since, with multiple updates and free DLC. The company also revealed recently that the game had sold over 1 million copies by the end of June, while the Switch itself had shifted nearly 5 million units.

In our Arms verdict, critic Kallie Plagge called the title a "strong, substantial fighting game," but one that "takes a while to really hit its stride." Read more in our full Arms review.

In other Nintendo Switch news, The Legend of Zelda: Breath of the Wild has also been updated, adding a new Zelda-specific news channel on Switch called Tips from the Wild. The news channel, which goes live today, allows players to obtain in-game items, though it's currently unclear what those items might be. In addition, Nintendo Switch online services undergo maintenance today.
