F-Zero GX (エフゼロ ジーエックス?) is a futuristic racing video game for the Nintendo GameCube console. Developed by Sega's Amusement Vision department and supervised and published by Nintendo, it was released in Japan, Europe and North America in 2003. F-Zero AX, the arcade counterpart of GX, uses hardware conceived from a business alliance between Nintendo, Namco and Sega. F-Zero GX runs on an enhanced version of the engine that powered Super Monkey Ball. F-Zero GX/AX was the first video game collaboration between Nintendo and Sega. The game received critical acclaim as one of the best racers of its time and the greatest racer on the GameCube platform.
F-Zero GX is the fifth released installment in the F-Zero series and the successor to F-Zero X. The game 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. Overall, the game 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.
