The game is set in the year 2042, after an object 'fell from the sky and changed our world', and after the creation of the 'Anomaly AI'. Online multiplayer was added in an update on January 24, 2015. Trials Fusion's multiplayer allows up to 8 players (PS4, Xbox One and PC) to race in different tracks, while the Xbox 360 version of the game only support 4 players. Trials Fusion also features a track editor, allowing players to create their own courses and games. Other vehicles included are motorbikes 'Baggie', 'Roach', 'Pit Viper', and 'Foxbat', minibike 'Donkey', and BMX bike, 'Rabbit'. Also new to the Trials series is the ability to choose a quad bike for a handful of levels: the 'TKO Panda'. Unlike in previous Trials games, players can also perform freestyle motorcross stunts while in the air by moving the right analog stick.

Trials Fusion, like the other games in the series, is known for, among other things, its notorious difficulty, particularly towards the end of the game. The player controls how the rider shifts their weight forward and backward in order to perform wheelies and stoppies as well as flips while in the air and controlling how the bike lands. The game uses 3D graphics, but is played on a 2D plane, so the rider can only move forwards and backwards. The player controls a rider on a physics-based motorcycle from the start of the level to the end while navigating a number of obstacles.

Like previous games in the series, Trials Fusion presents an arcade take on the real-life sport of observed trials.

By February 2015, the game had sold over 1.7 million copies. Critics praised the level design, controls, graphics, the futuristic setting, and the amount of content, but criticized the lack of tutorials for the game's create mode, and its similarity to past Trials games. Trials Fusion was generally well received upon release. Ubisoft released six paid DLC packs, as well as several free content updates. A companion game, Trials Frontier, released on iOS and Android devices and is designed to accompany the console and PC title. The game was released on Microsoft Windows, PlayStation 4, Xbox 360 and Xbox One in April 2014. A follow-up to Trials Evolution, it is the fifth game in the Trials series and is the first one to be released on a PlayStation platform. Trials Fusion is a platform racing video game developed by RedLynx in collaboration with Ubisoft Shanghai and Ubisoft Kiev.
