Super Xevious - Gump no Nazo [Model SX-4900]

Super Xevious Gump no Nazo, the sequel to the popular arcade game, was released for the Nintendo Famicom on September 19, 1986 in Japan at a retail price of 4900 Yen.

Xevious, the groundbreaking arcade game released in 1983, received widespread praise for its innovative gameplay and immersive world. It was a platinum seller on the Nintendo Famicom, selling over one million copies and helping to increase console sales by nearly two million units. However, by the mid-1980s, Xevious's popularity had waned as players gravitated towards games like Gradius with their larger scope and longer shelf life. In an attempt to reignite interest in the franchise, Namco released a sequel to Xevious on the Famicom. Unfortunately, the sequel received mixed reviews, was disliked by many fans for its significant departure from the original game, and was not commercially successful.

Gump no Nazo translates as GUMP's Mystery.

The development of Gump no Nazo was aided by Tose, a company that specializes in creating games for other developers. The game was not designed by Masanobu Endo, the creator of the Xevious series. Endo had left Namco a year before the game's release to start his own company, Game Studio, and was opposed to the idea of a sequel to Xevious, believing it was unnecessary.

GAMP no Nazo was the first Namco game on the Nintendo Famicom to not have a collection number on its packaging. This was a departure from Namco's previous practice of including collection numbers on the packaging for their games on the console.
