Wahoo! Super Mario Bros. Wonder has been shown off in a dedicated Nintendo Direct, which revealed its Dark Souls-esque online multiplayer.
When playing online, Super Mario Bros. Wonder lets you see other players – both friends and random people – running through courses beside you. Online players can plant standees to act as revive points and gift players items.
There’s also a karma-style system in play where helpful players are rewarded. This all works if you’re playing with friends in a lobby together (where you can see which courses everyone is in) or if you’re simply seeing other players you don’t know.
