You must lower Spring Man into the steel.
ARMS was one of the games in tonight's Nintendo World Championship broadcast, and during the competition a new update was teased.
The 3.2 update releasing later this month will add a new "badge stash" achievement system, which unlocks special badges that can be worn in online matches.
A character spotlight shown in the trailer also showed a new character, who appears to be a robotic version of Spring Man. It is not clear if the new form is a brand new character, or merely a new costume for Spring Man himself.
