Swamp Gas Visits the USA is an educational game that helps make geography more fun. There are three levels of map difficulty and players can easily determine the length of their geography discovery missions. They can decide if they will be visiting states, capitals, cities or landmarks, some of them or all of them. Players also have the option of 'close encounters' with the earthlings. Upon the completion of a geography mission the players can goof off in the Alien Arcade, enjoying one of the three and non-violent alien style arcade games.
