Rumble Pak (Nintendo 64)

The original Rumble Pak, designed for the Nintendo 64 controller, was released in April 1997 in Japan, July 1997 in North America, and October 1997 in Europe. The Rumble Pak provides force feedback while playing video games. Games that support the Rumble Pak cause it to vibrate in select situations, such as when firing a weapon or receiving damage, to immerse the player in the game. It requires two AAA batteries and is inserted into the controller's memory cartridge slot.
