TrackMania² Lagoon is the fourth environment of the TrackMania² series. As with other entries in the series, it includes single player, online multiplayer, and a track editor. As is the standard for the TrackMania games, each environment introduces a new vehicle with a new physics model alongside the new setting. This game brings version parity between the ManiaPlanet / TrackMania² games with the Console/PC game TrackMania Turbo, which introduced the Lagoon environment alongside adaptations of the previous three TrackMania² environments (Canyon, Stadium, Valley).
