Eidolon

The Eidolon - the 1985 first-person fantasy shooter for Commodore 64
from Lucasfilm Games.

Pilot a mysterious steam-powered craft through a series of underground
caverns, using energy orbs to battle monsters and harness the forces of
fire, ice, and time.

Core loop
- explore 3D labyrinths in your ether-powered Eidolon vehicle
- collect and fire colored energy spheres to attack or trigger effects
- defeat guardian creatures to unlock deeper chambers
- face a dragon boss at the end of each realm

Systems and items
- colored orbs - red (fire), blue (ice), green (growth), yellow (energy)
- energy meter - drains when shooting or taking damage
- radar - detects monsters and treasure in surrounding tunnels
- portals - transport to new caverns or bonus areas

Level design and feel
Fluid pseudo-3D caves rendered with smooth scaling and eerie depth. The
moody color palette and echoing sound effects build an otherworldly
atmosphere unique to early Lucasfilm experiments.

Why it is notable
- one of Lucasfilm Games’ first real-time 3D action titles
- shares technology lineage with “Rescue on Fractalus!”
- innovative blend of shooter mechanics and fantasy setting on C64

Tips
- conserve energy—shoot only when a hit is certain
- use matching orb colors to counter boss abilities
- retreat to earlier rooms to recharge or gather missed orbs
