This new Legend of Zelda: Tri Force Heroes video starts off with a rather strange (and somewhat hilarious) interlude, but then it actually gets informative. It’ll give you a quick rundown of how multiplayer works over three 3DS units, and some applicable scenarios in which the trio system is implemented (there’s PVP, too!).
It also has a super charismatic and erratic announcer, which helps you get through the roughly six-minute affair.
