Star Fox 64 3D for Nintendo 3DS have emerged from a Japanese retailer, specifically about the game's multiplayer mode. Unfortunately, it won't be playable online, but there will be local four-player versus battles and the game will use Download Play so your friends won't need their own cartridges. (Those cheapskates!)
The retailer also says that players will be able to take photos of themselves that will show up above ships in-game, similar to the functionality used in Ridge Racer 3D.
Star Fox 64 3D is still set for a July 14 release in Japan. No date has been announced for its North American arrival.
