F-Zero GX is a futuristic racing video game developed by Amusement Vision and published by Nintendo for the Nintendo GameCube console, which released worldwide in 2003. F-Zero GX runs on an enhanced version of the engine used in Super Monkey Ball. F-Zero AX, the arcade counterpart of GX, uses the Triforce arcade system board conceived from a business alliance between Nintendo, Namco and Sega. Published by Sega, it was released alongside GX in 2003.
F-Zero GX is the successor to F-Zero X and continues the series' difficult, high-speed racing style, retaining the basic gameplay and control system from the Nintendo 64 game. A heavy emphasis is placed on track memorization and reflexes, which aids in completing the game. GX introduces a "story mode" element, where the player assumes the role of F-Zero pilot Captain Falcon through nine chapters while completing various missions.
The F-Zero GX and AX project was the first significant video game collaboration between Nintendo and Sega. GX was well received by critics for its visuals, intense action, high sense of speed, and track design. Complaints centered on its sharp increase in difficulty that may alienate players.
