Nadeo is celebrating the upcoming tenth anniversary of the release of TrackMania with some further festivities besides those they already promised would mark the occasion (thanks Frans). They have now released the TrackMania² Multiplayer Demo, a free sample of TrackMania2 released alongside a new TM2 bundle as well as a larger bundle that also includes the original TrackMania United Forever. This trailer shows off the TM2 demo's Canyon, Stadium, and Valley environments, and here's word from ManiaPlanet News:
