Upcoming Nintendo DS RPG Contact, slated for a March 30 release in Japan by Marvelous and Grasshopper, will use the Nintendo Wi-Fi Connection for purposes yet unknown, given the presence of the WFC logo on the game's website.
Contact is a unique-looking RPG being produced by Killer 7 producer/director Suda 51, where a professor crash-lands on an alien planet and enlists the assistance of a local boy named Cherry to escape. The professor lives on one screen while Cherry plays out the game on the other.
Also of note, according to 4CR, is that the game may see a stateside release, according to Q&A from the game's creators. We'll keep you posted if we find anything out on this front.
