Club Nintendo of Japan is going to release a 2-3 players side scroller action on NDS called Screaming Rangers
Basically you scream at the DS for kick, punch, henshin, and team-up super move.
The good thing is this game looks really interesting.
The bad thing is it's not for sell, you'll need 500 points to claim this awesome game.
Club Nintendo is fricking amazing man, I wish I lived in Japan...
