Game Overview

Eclipsium is a first-person horror game that thrives on desperation. You play as a nameless Wanderer, drawn by a dying pale light through burial chambers, grotesque living sanctuaries, and vast cosmic darkness. The goal? Find “Her.” But every step feels like the environment itself is rejecting you. The atmosphere is relentlessly oppressive – each location is decayed, hostile, and governed by a logic you're never meant to fully grasp.

What sets Eclipsium apart from typical haunted-house horror is its willingness to abandon familiar corridors for surreal, flesh-built cathedrals and otherworldly voids. The visual language is a blend of cosmic horror, religious grotesquery, and dreamlike traversal. As I played, I felt the landscape itself was an enemy, shifting and disorienting me at every turn.
