Hydlide (ハイドライド, Haidoraido) is a 1984 action role-playing video game developed and published by T&E Soft. It was originally released for the NEC PC-6001 and PC-8801 computers in 1984, in Japan only; ports for the MSX, MSX2 (a separate port released on 3.5" floppy), FM-7 and NEC PC-9801 were released the following year. A Nintendo Famicom version was first released under the name Hydlide Special on March 18, 1986 in Japan; three years later, in June 1989, that version saw a North American release for the Nintendo Entertainment System by FCI, its title having been returned to simply Hydlide. The game sold 2 million copies in Japan, across all platforms.
In April 28, 1995, a remake was released for the Sega Saturn under the title Virtual Hydlide, both in Japan and western countries.
In the kingdom of Fairyland, three magic jewels were enshrined in the palace to maintain peace in the kingdom. One day, an evil man broke into the palace and stole one of the three magic jewels. Without the third jewel, the two remaining jewels lost their magic sparkle. The magic spell that sealed the power of Boralis, the most vicious demon in the kingdom, was broken. During the turmoil which followed, the last two jewels were stolen. Boralis cast a special magic on Princess Ann, turning her into three fairies, and hid her somewhere in the kingdom. He then let loose a horde of monsters across the land and became the ruler of the kingdom.
Super Hydlide is an action role-playing game for the Sega Genesis/Mega Drive. It was originally released in 1987 in Japan only under the title Hydlide 3: The Space Memories (ハイドライド3 闇からの訪問者, Haidoraido 3: Yami Kara no Hōmonsha) for the MSX, MSX2, and NEC PC-88. Ports were also released for the Nintendo Famicom and the Sharp X68000. The game was developed by Hydlide series veterans T&E Soft and released worldwide on the Sega Genesis / Mega Drive on October 6, 1989, in Japan, early 1990 in the United States, and 1991 in Europe. This remake evidences substantial graphical upgrades to the original Hydlide 3, though the gameplay remains largely identical. Before its release, it was called Hollo Fighter in some Sega advertising material and was one of the first third party published titles to be released in the U.S, the other being Air Diver.
Many years after the events of Hydlide II, an explosion of flames appeared near The City of the Woods. After that, enemies were everywhere. A young man is chosen to find the source of the evil.
