Silhouette Mirage, also known as Silhouette Mirage: Reprogrammed Hope (シルエットミラージュ ~リプログラムド ホープ~), is a side-scrolling video game that was developed by Treasure. Initially published by ESP for the Sega Saturn on September 10, 1997, in Japan , the game was later ported to the PlayStation on July 23, 1998, in Japan. In 1999 Working Designs translated and published the game in North America. In 2010 the game was released for the PlayStation Network, albeit only for the Japanese store.
The setting is Earth, during a post-apocalyptic year 2000. Prior to the events in the game, a group of scientists conducted genetic experiments in a great facility called Edo. From their activities emerged the two attributes: Silhouette and Mirage. These aspects manifested in a child named Armageddon (Clod).
The two aspects were based on the dualistic nature of Yin and Yang: One's existence is crucial to the other's. Despite the complementary nature of the attributes, they repelled each other. As a result, Armageddon's attributes split to form two pure figures: Megido and Har, respectively the self-proclaimed Silhouette and Mirage leaders.
