Super Xevious: Ganpu no Nazo

Super Xevious: GAMP no Nazo is a vertical scrolling shooter developed for the Family Computer by Namco in 1986, and not to be confused with the update to the original arcade Xevious called Super Xevious. Unlike the original Xevious, this version was not designed by Masanobu Endoh, who had left Namco. Endoh opposed the idea of creating a sequel to Xevious, as he felt it was unnecessary. Presumably, Namco was hungry to cash in on the success of Xevious, so they created this game.

GAMP no Nazo contains some key differences from the original. The game contains discreet stages which are not composed of vertical strips of the same basic terrain. Per the "nazo" ("riddle") part of the game's title, each stage contains some problem that the player must solve in order to advance to the next stage. These solutions may include flying into a certain portion of the screen, collecting a particular power-up, or destroying a particular target. If these objectives are not met, the game repeats the same level at an increased difficulty. As mentioned, this game also introduces power-ups to Xevious, which include a rear-firing Zapper, shields, and a larger Blaster.

In addition to being released on the Family Computer, a version of the game was released for the Nintendo VS. System arcade hardware. This version is known as VS. Super Xevious, though the game itself bears the same title as the original version.
