F-Zero GX is a 2003 racing game developed by Amusement Vision, a division of Sega, and published by Nintendo for the GameCube. It was released in Japan on July 25, 2003, North America on August 25, Australia on October 24, and Europe on October 31. Sega also released an arcade version, F-Zero AX, which uses the Triforce arcade system board.

F-Zero GX retains the high-speed gameplay of the previous F-Zero games, with an emphasis on track memorization and reflexes. It introduces a "story mode", in which the player completes missions as Captain Falcon through nine chapters.

The project was the first significant game collaboration between Nintendo and Sega. It runs on an enhanced version of the game engine used in Super Monkey Ball (2001). GX received positive reviews for its visuals, intense action, sense of speed, and track design, though its difficulty was criticized. In 2025, it was rereleased on the Nintendo Classics service for the Nintendo Switch 2.

Gameplay

F-Zero GX is a futuristic racing game in which up to thirty competitors race in an intergalactic Grand Prix. It retains the basic gameplay and control of the previous F-Zero game, F-Zero X (1998) on the Nintendo 64. has its own performance abilities affected by its weight, and a grip, boost, and durability score. Before each race, the player can adjust a vehicle's balance between acceleration and top speed. Energy is also used to boost, which becomes possible after the first lap. By holding both shoulder buttons, vehicles can drift around corners. This technique, called "snaking", delivers a massive increase in speed, but it is best used on the easier tracks, when racing alone in Time Trial, and with heavy vehicles with a high grip rating and given high acceleration. Nintendo said snaking was an intentional inclusion, but IGN said this may be "damage control".

If the player has a "spare machine"—the equivalent of an extra life— the race can be restarted even if their vehicle is destroyed. Players start each cup with more vehicles on lower difficulty levels. Players receive energy for destroying competitors through combat, and receive an additional spare machine for every five contenders they destroy.

In the multiplayer mode, two to four players can compete simultaneously. In the time attack mode, the player attempts to complete a track in the shortest time. Players could enter a password received after a time attack on the F-Zero website to enter the online ranking Ghost data, transparent re-enactments of the player's time attack performances, can be saved on memory cards to race against. Up to five ghosts can be raced against simultaneously. The replay mode allows saved Grand Prix and Time Attack gameplay to be replayed with different camera angles and in-game music. The pilot profile mode has each character's biography, theme music, information on their machine, and a full motion video sequence.

Customize mode is divided between the F-Zero Shop, Garage, and Emblem Editor. The shop is where opponent machines, custom parts for vehicle creation, and miscellaneous items such as story mode chapters and staff ghost data can be purchased with tickets. Tickets are acquired as the player progresses through the Grand Prix, Time Attack, and Story mode. In the Garage section, players can create a machine with three custom parts or print emblems on any vehicle. The parts are divided into body, cockpit, and booster categories, and affect the vehicle's overall durability, maximum speed, cornering, and acceleration. The Emblem Editor lets players create decals.

F-Zero GX is the first F-Zero game to feature a story mode. Toshihiro Nagoshi, one of the co-producers, said the development team wanted to explain the characters' motivations and flesh out the game world. which was conceived from a business alliance between Sega, Nintendo and Namco. The hardware allows for connectivity between the GameCube and arcade games.

F-Zero AXs arcade cabinet was manufactured in standard and deluxe versions. The standard version is a regular sit-down model, while the deluxe version is shaped like Captain Falcon's vehicle and has a tilting seat simulating the craft's cockpit. IGN demoed the Cycraft version dubbed "F-Zero Monster Ride" at the 2003 JAMMA arcade show. The Cycraft machine, co-developed between Sega and Simuline, is a cabin suspended in midair controlled by three servomotors for an in-depth motion-based simulation.

AX features 14 playable vehicles with their pilots, consisting of ten newcomers and the four returning characters from the original F-Zero, as well as six race tracks. Similarly to GX, Players can store up to four machines from GX on a memory card, then use them in AX. If a memory card is used with a magnetic stripe card, players can also enter stored GX machines into the F-Zero AX internet ranking system and transfer custom AX machine parts to GX. AX content can also be acquired by completing GXs tougher challenges, or through the use of a cheat device.

Development

After Sega transitioned from first to third-party development in 2001, they developed a close relationship with Nintendo, its former competitor in the console wars. On February 18, 2002, Nintendo announced the "Triforce" arcade board, developed by Nintendo, Namco, and Sega. Sega wanted to support it with software that would "stand out and draw attention to Nintendo's platform".
