– Free Mode, where you choose a stage and then get matched up with a party automatically. Anyone can join in, but you’re only allowed to chat via the in-game keyboard — none of the PictoChat-style “visual chat” functionality is available.

– Friend Mode, which allowed for the same visual chat that regular DS wireless play lets you enjoy. You can assign new friends in this mode, and parties of friends-of-friends are also possible, so you don’t actually need to trade codes with every single person in your hunting expedition — just one is fine.

– Single Mode, a one-player-only version of online play. What’s the point? Sega isn’t telling us yet, but there must be something to it.
