Tōjin Makyō Den: Heracles no Eikō (闘人魔境伝 ヘラクレスの栄光, "Legend of the Fighting Demon's Lair: Glory of Heracles"^[6]) is the first game of the series. The player takes the role of a young Heracles who seeks to rescue Venus from captivity in Hades.

Heracles no Eikō II: Titan no Metsubō (ヘラクレスの栄光II タイタンの滅亡, "Glory of Heracles II: Titan's Downfall"^[6]) is the second game of the series. Unlike the first game in the series, Heracles is no longer the player-controlled character.

The party system is introduced, along with time-flow, where the game passes between daytime and nighttime. Though no longer containing a particularly unique game system, Heracles no Eikō II is characterized by its tragic, dramatic storyline, which employs various motifs from Greek mythology.

The game's scenario was written by Kazushige Nojima.^[7]

Heracles no Eikō III: Kamigami no Chinmoku (ヘラクレスの栄光III 神々の沈黙, "Glory of Heracles III: Silence of the Gods") is the third installment of the series. Initially published for the Super Famicom, it was released on the Japanese Virtual Console in 2007 by Paon and on mobile phone in 2008 by G-Mode.^[8][9]

The hero begins the game in a state of total memory loss, but discovers that he has acquired a mysterious power that shields him from bodily harm, essentially making him immortal. An immortal character can execute certain actions that other characters cannot, like jumping off high cliffs without being injured.

Heracles no Eikō: Ugokidashita Kamigami - The Snap-Story (ヘラクレスの栄光 動き出した神々 The Snap-Story, "Glory of Heracles: The Gods Began to Move - The Snap-Story") is the fourth game of the series and is the only spinoff of the series. It is the only other game in the series that features Heracles as the main playable character. The story is set shortly after the events of the first game, where Heracles is summoned by Zeus to prevent the resurrection of Cronus by Bloodlord and his minions.

The battle system is like that of the first game, where Heracles is limited to attacking, defending and using items, but during a fight the player can be assisted by a God which they have chosen to accompany Heracles. Gods do not level up, but they usually have high stats and powerful magic. As the player levels up, they can gain another God they can bring with them from Olympus, but they are only allowed to take one at a time.

Heracles no Eikō IV: Kamigami kara no Okurimono (ヘラクレスの栄光IV 神々からの贈り物, "Glory of Heracles IV: Gift from the Gods") is the fifth installment of the series (fourth game in the main series), released after the portable spinoff Heracles no Eikō: Ugokidashita Kamigami. The game was made available for the Virtual Console in 2008.^[10] The player takes the role of a young man whose spirit was separated from his body.

The game's plot and setting are very loosely based around various episodes from Greek mythology, with a particular focus on Atlantis and the tale of Pandora's box. In addition to writing the scenario, Kazushige Nojima was also the director for this game.

Glory of Heracles, known as Heracles no Eikō: Tamashii no Shōmei (ヘラクレスの栄光 魂の証明, "Glory of Heracles: Proof of the Soul") in Japan, was developed by Paon and published by Nintendo in 2008 for the Nintendo DS. This is the first entry in the series that was not developed by Data East and the first to be published by Nintendo as a first party property, however, former Data East employees and writers of Heracles no Eikō II, III and IV again wrote the scenario.^[6] Revealed at E3 2009, the fifth game would be the first in the series to make an international release in 2010.
