Silhouette Mirage is a 2D action side-scrolling video game developed by Treasure and released in 1997. The game's primary mechanic is the two opposing attributes, "Silhouette" and "Mirage" and the way they are able to cause damage to each other. Shyna features as the female protagonist who is able to switch between these attributes at will by facing either left or right on-screen. Secondary mechanics in the form of various melee moves are used to get enemies onto the correct side of the screen so that when Shyna is facing them, she is able to use the correct, opposing attribute to damage them.
