"Grand Theft Auto: San Andreas" is a role-playing video game in which you play as a criminal who robs people of their money, steals vehicles and more. One of the vehicle available is a motorcycle. Modifications have been made to "Grand Theft Auto: San Andreas" so the motorcycle and your criminal have the appearance of the "Ghost Rider" comic book character. You can perform stunts with "Ghost Rider" by moving the motorcycle using the arrow keys when it's in the air.
