You discover the Eidolon, a strange 19th century vehicle, in an abandoned laboratory. Investigating this device, you are accidentally transported to another dimension and 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 you soon finds that his only chance of survival lies in this mysterious vehicle and its powerful energy weapon. The objective is to successfully navigate through all of the game's levels, defeating the dragon guardian at the end of each level. You navigate through each maze and collect 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.
