The producer of Sonic Lost World, Takashi Iizuka, has confirmed that there will not be any online multiplayer for the Wii U version of the game, but rather only local co-op mode. Below is his quote and explanation:
“We’ll have different multiplayer modes on both Wii U and 3DS. On the Wii U, there’s booth cooperative and versus multiplayer. In cooperative play, Sonic will be using the Wii U GamePad and someone can be supporting Sonic in co-op with the Wii Remote. In versus mode, one player will be playing on the TV screen and the other player will be racing using the GamePad so you don’t have to have split screen. You both have your own screen and can race each other. The Wii U multiplayer is not on the Internet. It’s basically everyone sitting on the same couch. The 3DS for the first time we’re having 4-player versus racing over Wi-Fi and the Internet.”
It should also be noted that the Nintendo 3DS version of Sonic Lost World will have four player racing that is done via wi-fi. What do you think about this news from Iizuka?
