Trials Fusion is an arcade motorcycle game. It is the sequel to Trials Evolution and the fifth game in the series. Improvements over the last game include more detailed graphics and futuristic, high-tech backgrounds as completely new environment.

The goal of the game is to race on fantastical tracks with ramps and unrealistically high jumps and reach the finish with as few crashes as possible. The game has a 2.5D environment, in that it is fully 3D modeled but players can only move on a single lane. Career is the main game mode with skill challenges for each tier as an extra challenge next to the regular tracks. Entirely new are level-specific challenges that can be completed for each track, for instance by restricting or forcing a certain riding style.

The player can hit gas and break to move, and lean forward or backward to balance the bike. During long jumps player can perform mid-air stunts like back flips for bonus points. New to the series is the ability to perform free stunts in the air and the addition of quad bikes next to the regular motorcycles. In multiplayer mode, both offline and online, up to four players ride in individual lanes. When a player crashes or goes off screen they respawn in a position close to remaining players. The game contains a track editor to create custom courses in the Create mode, but unlike the previous game Trials Evolution it is no longer possible to create supercross courses. Tracks can be shared and downloaded through the in-game Track Central.
