The previous update version 2.0 that Nintendo released for Arms contained "Hedlock Scramble," a new arena called "Sky Arena," and an official addition of a new fighter named "Max Brass." Now, another update is now available for download that contains a new "Training" exercise with some adjustments to both fighter and arms (weapons used in battle). Update version 2.1 moves the "Training" option to the top menu along with additional five exercises with difficulty level indications.

Furthermore, the company also adjusted the way the rush gauge fills.

The amount is decreased when an attack does not connect with the opponent. A quick tutorial on how to switch targets will be displayed when 3 to 4 players start a battle. Also, a cursor will be displayed on the target player for a set amount of time. Next, Nintendo also changed the pause, results, and replay menus in "Training" for convenience. Lastly, corrected a bug that causes the game to hang up when players skip the ending for a particular time.

Fighters adjustments

Other fighters and arms were adjusted as well. Here is the information via Nintendo America below:
