Wondering how wireless "tag mode" will work on Nintendo's new 3DS? You're not alone. Fortunately, a trailer for Super Street Fighter IV has been loosed upon the internets giving us a pretty decent overview of what serendipitous game play will be like. To start with, a minigame feature lets you automatically fight your nearby rival's collectable action figures even while the 3DS is tucked away in your bag. The more you fight the more figures you collect. Then there's the more obvious wireless battle mode for active multiplayer gameplay with nearby 3DS owners. Should make for some interesting chance encounters
