Ubisoft announces Welcome to the Abyss, a DLC coming next month to Trials Fusion as the third of six planned releases of new content for the racing game. There are screenshots and details on the UbiBlog, and here's a bit:

We’ve been out in the wastelands and up among the clouds, and now Trials Fusion is taking us under the sea. The game’s third DLC pack, Welcome to the Abyss will have players exploring mysterious underground ruins. Surrounded by ancient machinery powered by strange relics, players will take on 10 new tracks and 24 challenges (with 5 new achievements that can be earned). In addition, you’ll have access to over 100 new objects for the track editor so you can build a beast of your own and send it out in the world for others to try.
