The Eidolon was one of two games that were part of Lucasfilm Games' second wave in December 1985. The other was Koronis Rift. Both took advantage of the fractal technology developed for Rescue on Fractalus!, further enhancing it. In The Eidolon, Rescue's fractal mountains were turned upside down and became the inside of a cave.
In addition to common cassette formats, the Atari and Commodore C64 versions of the game were supplied on a flippy disk. One side had the Atari version, and the other had the Commodore 64 version. The Atari version required an XL/XE with 64kB or more memory.
The player discovers the Eidolon, a strange 19th-century vehicle, in an abandoned laboratory. As the player investigates this device, he is accidentally transported to another dimension and is trapped in a vast, maze-like cave. The creatures in this cave, sensing the energy emanating from the Eidolon, are woken from a long slumber, and the player soon finds that his only chance of survival lies in this mysterious vehicle and its powerful energy weapon.
The objective of The Eidolon is to successfully navigate through all of the game's levels, defeating the dragon guardian at the end of each level. The player navigates through each maze and collects energy orbs, which come in four different colors (red, yellow, green and blue). Along the way, various enemies wake up and attack the Eidolon, attempting to absorb its energy. Some enemies also fire orbs at the Eidolon, of which all but the red orbs can be absorbed by pressing the space bar at the right time to replenish the Eidolon's limited energy.
Green orbs also have the power to transform other enemies into different kinds of enemies. Blue orbs can freeze enemies temporarily, giving the player a momentary advantage in a fight.
Each level contains three diamonds, each guarded by an enemy of a specific color. After defeating each of these enemies and collecting the diamonds, the player can proceed to the dragon that guards the exit. There are eight levels in a game. The game is over when the player has successfully defeated the final dragon or runs out of time.
Zzap!64 gave the game a Gold Medal award, with an overall 97% score. The summary of the reviews from their three reviewers was "Lucasfilm's most original release yet, containing outstanding graphics and gameplay elements. The Eidolon is both immaculate in it's [sic] conception and execution. Not to be missed."
Gregg Williams of Computer Gaming World disliked The Eidolon. He stated that it was as difficult as Koronis Rift but with no save game feature. While praising the graphics and sound, Ardai criticized the game for "a lack of imagination. You get transported to god-knows-where ... and you basically shoot everything in sight. Is this a reasonable—let alone responsible—way to explore a new world?" Charles Ardai later described the game in the magazine as "one of the worst" of 1986.
