Gameplay

Like most racing video games, players must reach the end of a track as soon as possible. Unique to the Fast series is the polarity mechanic, where players collect boost energy by switching between two colors. Each color has respective boosts and jump pads, which can only be used if a player is currently its respective color. Upon completing a race, players are rewarded a number of points, depending on which place of 8 they finished in. At the end of a cup, the player must rank in the top 3 of racers to unlock the next cup. The player has 12 cups of 3 courses available, with only 3 cups to choose from at the beginning of the game. The game can also be played online with up to 4 players locally and up to 8 players online.

The game features a single-player campaign with 10 cups to unlock, containing 30 courses total, along with 15 unlockable vehicles. These vehicles can be fused together for a total of 210 combinations.^[1] The game also contains multiplayer components, featuring split-screen multiplayer mode for up to 4 players, as well as local communication and online modes with 2-8 players. Another extra mode called Hero Mode is available, using the same tracks as the campaign with higher difficulty and with the boost meter doubling as a health bar, similarly to games in the F-Zero franchise.
