Short: Titan Diamonds is a game with Lunar Lander style elements.
Long: In the year 2574 a lot of things have changed. Humans have colonized our solar system and the O81b “flying saucer”is the primary means of getting around town. However, some things don’t change, specifically the need for diamonds. In 2574, the largest known diamond in the solar system was found in the moon, Titan. But in the process of trying to mine it, the 2 petaton atomic bomb used was overkill and scattered diamonds across the planet and across the solar system. You are one of the many that have equipped their O81b’s with rock blasters and set off to mine for the diamonds. But watch out, the explosion also caused a lot of meteorites! Good luck diamond hunter, and get rich!
