Overview
Subterraneans was originally developed as a 3D shooter using the DOS-based “Pie in the Sky” engine, structured with a level design inspired by the classic Wolfenstein architecture. The game was intended to be released in 1996 by Full Moon, but it remained an unfinished project, making it one of the more obscure DOS titles from the era. Specific details about the storyline are limited since the project did not reach full commercial completion.
