While on one of your usual trips to the American west to terrify some locals, your UFO goes haywire and crash-lands in the desert. With the CIA due to arrive at any moment, control your friendly robots to stay alive, upgrade themselves, and salvage bits of your flying saucer so you can get off this godawful rock.
Left-click robots to select them, and right-click to send them to a location. Wells provide water, and metal mounds provide metal. Make sure to get them all back to the ship before nightfall!
