Nintendo had a direct today specifically about ARMS. They announced tons of new characters and gave a look at the various battle modes that are within the game. ARMS is currently on sale and can be pre-ordered for the Nintendo Switch right here. Nintendo introduced several new ARMS Battle Modes as well.

You can get a 2 point shot or 3 point shot.
