Today the surprising Mini Nintendo Direct has guaranteed us several new interesting announcements, including among them a small teaser on the future of Super Smash Bros Ultimate. As confirmed, the new fighter, as well as the first member of the second Fighter passport, will be a character from the IP of Arms. This is an exclusive Nintendo which unfortunately does not receive further post-launch support due to its not extremely successful debut.
We don't know who this is yet, but it has been confirmed that this will come within Super Smash Bros Ultimate a June. The mechanics of the extendable arms seen in Arms will surely impress us in the arenas of the famous Nintendo fighting game.
