If you was wondering whether Super Mario Odyssey would be supporting multiplayer, you may be a little disappointed but it will feature co-op gaming much like it did in Super Mario Galaxy. By that I mean that 2 players can play at the same time using each Joy-con, One to control Mario and the other to control Cappy. By controlling Cappy, the second play can defeat enemies and collect coins including the hard to reach ones and the first player gets to enjoy playing as Mario. you can see for yourself via the video below.
