Due to their high quality and low availability, many rare games on the Sega Saturn were among the first to dramatically increase in price following the console's demise. Games such as Panzer Dragoon Saga, Shining Force III and Dragon Force soared in price as collector's scrambled to add them to their collections.
Enemy Zero, while not considered one of the best games on the system, became one of those games.
The second entry in the D franchise, Enemy Zero is much different than the previous game. Here, players have to contend with invisible enemies using only sound to find their location, whereas the original was a more point-and-click affair.
To get a copy of Enemy Zero will cost approximately $150.
