The Eternal Castle: Remastered is a remake of the original "Eternal Castle" from 1987, with additional game mechanics, sophisticated sound design, polished 2-bit CGA animated graphics, and modernized game design.

Numerous outlets have questioned the title's "lost game" backstory as almost no corroborating accounts have been found to verify the title's development backstory.
