Silhouette Mirage is a side-scrolling action game. The basic gameplay is somewhat similar to that of Gunstar Heroes. The game's standout feature is the concept of the two attributes. Depending on the enemy's attributes and the type of attack used by Shyna, damage can be increased, and spirit (equivalent to magic power) can be absorbed from enemies. Shyna can dash, jump, crouch, slide, and grab enemies, executing combo attacks. It is also possible to master moves, acquire money, and purchase special creatures called "parasites", which teach Shyna various types of attacks.
