For a limited time, Nintendo is offering a free DS Rumble Pak when you buy Metroid Prime Hunters (a $20.00 value). Before, the Rumble Pak was packaged only with Metroid Pinball, but Nintendo has just started to release the Rumble Pak separately. As of right now, only a few games use the Rumble Pak: Metroid Prime Hunters, Metroid Pinball, and Mario and Luigi DS. More games are bound to use it in the future. Take advantage of the deal if you can. and the Rumble Pak will work with the DS Lite. Check your local electronic stores for details and to see if they are offering the deal.
