SpongeBob SquarePants and the Nicktoons Gravjet Racing (cancelled Xbox Live Arcade racing game; 2009)
SpongeBob SquarePants and the Nicktoons Gravjet Racing was a racing game planned for release in 2009 featuring characters from SpongeBob SquarePants, Barnyard, Ren And Stimpy, Fanboy And Chum Chum, My Life As A Teenage Robot and possibly more. Not much is known about the game and not even the name of the publisher was ever revealed.
The game would have played similarly to the game series' Mario Kart and F-Zero in the sense that it would have played at a fast pace and had a feature for battling with weapons along with panels on the track which when a character drives over them, the kart would have slowed down or spin out. Every character would be assigned a unique kart which stayed in the art style of the series represented but made into futuristic versions.
The game never left the beta stage and was cancelled due to financial difficulties. No builds of the game have been released online, only screenshots.
