Color Dreams, a company that was not an official Nintendo licensee, launched the game in 1990. As a result, the game lacked an official Nintendo quality seal and was not widely marketed. The game is a side-scrolling action game with a pretty high degree of difficulty and a unique power-up system. However, its scarcity and lack of official Nintendo support have led to its popularity as a collector's item. While the game is still available through online markets and vintage game retailers, it is uncommon compared to other NES titles and might be tough to locate in decent condition. Because of its scarcity, Silent Assault has become one of the most costly and precious NES games for collectors. However, because to its relatively obscure position and lack of mass recognition, its value is often lower than that of other rare NES titles.
