Let's! TV Play Dragon Ball Z: Scouter Battle Taikan Kamehameha appeared in Japan in 2007 as another entry in Bandai's plug-and-play television game series. Its main innovation was a head-mounted accessory styled after the Scouter worn by characters in Dragon Ball Z, used together with finger-mounted sensors. Players could perform physical movements to trigger attacks such as the Kamehameha during battles. The games were built into the unit, requiring no cartridges or discs.
