The gameplay is similar to the other Mario & Luigi games, it is most similar to Mario and Luigi Paper Jam and Mario and Luigi Dream Team, since there are now 4 characters instead of just 2 the "Y button" now controls Wario and the "X Button" now controls Waluigi, because of this Paper Jam's emergency block has been reassigned to the "D pad buttons" , the game features giant battles similar to Mario and Luigi Bowser's Inside Story and Dream Team, while in giant battles Mario, Luigi, Wario and Waluigi will control a giant mech, during these giant battles the player can use motion controls with they want to inorder to use new features of the giant battle machinic
