Switch exclusive ARMS is scheduled to be released on June 16, Nintendo announced during the Nintendo Direct presentation last night.
Nintendo unveiled the new character Min Min during the ARMS part of the show. She not only uses her hands to deal damage on her opponents, but her feet as well. On top of that, Nintendo revealed a previously unannounced 2v2 mode mode.
