Famitsu’s news post also came with a bunch of in-game screenshots. Medabots DS has three on three battles plus countrywide (read: Japan only) online play. Win Nintendo Wi-Fi battles to earn Medagachacoins. You spend these in a capsule machine which is filled with parts and medals.
Natsume brought the other Medabots games to North America, but they haven’t said anything about Medabots DS yet.
