H2Overdrive is a cancelled powerboat racing game developed by VisiWare, that was going to be published in 2001 on the Playstation 2 by Crave Entertainment. In the game players would have been able to race in the fictional Global Powerboat Racers League, which features events set in locations ranging from rivers and lakes to the surface of the planet Mars, with 7 modes of play: championship, simple race, duel, survival, checkpoint, ghost, and cat and mouse. The project was never released, maybe because of some problems with the publisher or for quality reasons.
This game is not related to the arcade-only H2Overdrive, developed by the guys who made the original Hydro Thunder.
