Alien Syndrome (set 5) is another arcade release variation, this time using the Sega System 16A hardware. Like other releases, it's a rail shooter featuring intense combat against alien enemies. However, using the System 16A might result in some slight graphical or performance differences compared to versions running on System 16B.  The FD1089B 317-0037 identifier suggests a specific hardware revision.  Sega remains the developer and publisher of this arcade version, providing a unique perspective within the context of the game's different releases.
