Ubisoft has confirmed that the update that is rolling out to Trials Fusion owners does include the promised online tournaments that was announced for the game. This update is not part of the six DLC packs that make up the season pass for Trials Fusion from what we understand.
The new online tournament mode allows players to compete online against other Trials Fusion players in time-limited tournaments. Winners will get new in game stuff like gear, bike parts, in game money to spend, and of course experience points. The prizes are handed out according to your placement on the tournament leaderboard, but we are not sure if everyone is a winner or not, we will have to wait and see.
Speaking of the DLC packs for Trials Fusion, the first of these will arrive this summer.
