The official sequel, but not the planned sequel. While the canceled Hydro Thunder 2 had the original development team, HTH came after Microsoft acquired the rights to the IP. They granted use of the license to Vector Unit, who were developing an unaffiliated game that got the HT skin partway through development. The game was released on July 28, 2010, about 14 months after OG Hydro developers released their spiritual sequel H2Overdrive.
