is a 1993 vertically scrolling shooter video game developed by Compile and published in Japan by Tonkin House for the PC Engine Super CD-ROM². Whereas many shooting games of the era take place in a science fiction setting, this game instead mixes heroic fantasy and ancient Greek mythology. The game follows Silphia, a maiden warrior reincarnated as a demigoddess under Zeus after her demise in battle, facing against the forces of Hades, who has been possessed and manipulated by the creatures once imprisoned in Tartaros.
Its gameplay is similar to previous shooters by Compile, with the player fighting enemies and bosses, while avoiding collision with their projectiles and other obstacles. Directed by Junichi Nagatsuma and produced by Ikuro Urai, the title was the last shooter by Compile until Zanac X Zanac (2001) and had a limited run. It received mixed reception from critics.
Gameplay
Sylphia is set in a classical Greek setting, during a time when gods and humans once dwelled together. Hades, god of the underworld, has fallen under the influence of monsters once defeated by the gods on account of a mysterious mask, and has begun sending those monsters out to ransack and dominate the land above, forcing the gods to retreat to Mount Olympus. The game stars a Hellenic woman named Silphia whose city is under attack by those underworld forces. The young maiden warrior is reincarnated as a demigoddess under Zeus after her demise in battle, tasked to destroy the monstrous armies and seek out and put an end to Hades's madness. She is given wings much akin to a dragonfly, which allows her to fly through the air. She must then try to free the rest of the Greek world from control of the forces of Hades, facing off against mythological figures including giants, a Minotaur, a griffin, and Talos.
The game is a vertical-scrolling where players control the above flying woman (rather than a space ship which is typical of games from this genre). Its gameplay is similar to previous shooters by Compile; The player controls Silphia through eight stages over a constantly scrolling background, populated with an assortment of enemy forces and obstacles, and the scenery never stops moving until a boss is reached, which must be fought to progress further. Stages have a mid-boss, and then an end boss at each stage.
Silphia has a main weapon that can be powered up by collecting power-up items. There are also four different special weapons based on the four classical elements she can obtain, which affect her shooting method, and these can be upgraded if the same weapon that is currently being used is picked up or by collecting power-ups. Silphia can execute a powerful lightning beam attack as well, but it must be charged after being unleashed by collecting crystals. Getting hit by enemy fire or colliding against solid stage obstacles decreases Silphia' health and the game is over once her health is depleted, though the player has the option to continue, but with a penalty of decreasing the Silphia's firepower to her original state.
Development and release
Sylphia was developed by Compile, which had previously created Seirei Senshi Spriggan and Spriggan Mark 2: Re-Terraform Project for the PC Engine, but their name is never mentioned in the credits despite many of its staff members working on the project. It was directed by Junichi Nagatsuma and produced by Ikuro Urai. Shinichi Nogami served as the game's sole programmer. Kōji "Janus" Teramoto acted as co-graphic artist alongside Aya "Riu" Shimazaki, Hideo Hotta, Neko Koneko, Shōji Mizumoto, Shunsuke Takashima, and Tenji Satō. The soundtrack was scored by Einosuke Nagao, Katsumi Tanaka, Keiji Takeuchi (of Spriggan Mark 2), Satoshi Shimazaki (of Robo Aleste), and Tsuyoshi Matsushima. Other people also collaborated in its development, including Takayuki Hirono serving as game system adviser.
The game was first unveiled at the Makuhari Messe convention center in a fifty to sixty percent complete state. The title was published in Japan by Tonkin House for the PC Engine Super CD-ROM² on October 22, 1993. The game has since become a rare rare collector's item that commands high prices on the secondary game collecting market alongside other PC Engine shooting games titles such as Ginga Fukei Densetsu Sapphire, Steam Heart's, or Rayxanber II or Rayxanber III. It was the last shooter by Compile until Zanac X Zanac (2001).
