Thunderbolt II

Sinopse em inglês

Thunderbolt II is an unlicensed vertical scrolling shoot-'em-up released for the Sega Mega Drive in 1995. There is not thought to have been a Thunderbolt I - more likely it is borrowing its name from Raiden II, a 1993 arcade shooter by Seibu Kaihatsu that is a sequel to Raiden.
