Mission Scavenger Express was designed and equipped to search for valuable sources of energy on Mars and for combat with any suspicious looking Martians.
Indirect commentary on the history of imperialism in the 20th Century. Lots of parallels with the history of Iraq (first being occupied by the British, now by the United States.) Comments on the thirst for oil in what some would call the Age of the American Empire. This video animation stars a mars rover, martians, oil, British Petroleum, Dick Cheney, George Bush, Texaco and an American tank! What a star studded cast!
