Super Thunder Blade (スーパーサンダーブレード) is a shooter for the Sega Mega Drive/Genesis console, published by Sega. It was one of two launch titles for the console in Japan (the other being Space Harrier II). It is a follow-up to the arcade game Thunder Blade.
As in its predecessor, the player takes control of an helicopter which is used to attack a group of guerrillas. The helicopter itself uses guns and missiles, and can also air brake. A distinctive feature that also appears in the arcade game is the use of different viewpoints during the entire game; during normal gameplay and when fighting sub-bosses, the game utilizes a third-person perspective from behind the helicopter, similar to Space Harrier, but the camera changes to a top-down perspective when fighting bosses. Super Thunder Blade had four stages of play.
