Members of Japanese Club Nintendo can get their hand on an interesting game...

Zekkyou Senshi: Sakeburein, or Exclamation Warriors is a game exclusive to Club Nintendo members, that is controlled via microphone only. The premise of the game is to shout attacks and transformation names like in some Anime. The game is multiplayer only and costs 500 points.

It's unlikely this game will ever leave Japan, which is a pity because it looks fun (and funny), but check out the video in this page: Club Nintendo Site - Click Here!
