Using the Wii Balance Board and Wiimote/Nunchuk combo, you climb a rock wall.  It’s as easy as that.  At the Game Developers Conference that just happened, the Rock and Roll Climber game was previewed.  The weirdest part?  As soon as you negotiate the wall, the character grabs a guitar out of the ground and pulls off a heavy metal lick.

Well, that’s – um – hey cool!

The interface looks pretty cool – the Balance Board detects balance shifting, and the climbing controls look interesting.  I’ll reserve judgement.

Thanks, Kotaku!
