About this game

Eclipsium is a first-person horror game where you play as the desperate Wanderer. In search of Her, his path leads through hellish tombs, cathedrals of flesh and even through space, immolating himself and sacrificing anything to achieve his goal.

Don’t stop

There is no safety or comfort in Eclipsium. Let the pale light guide you through, as every place hides its own path to escape.

Enter the spiral

Everything fades and senses dull in this endless darkness. But with you remains your power - a twisting, transmuting hand, ready to carve a way through whatever stands before you.

Find her

Her weak light, now little more than a whisper of a memory, pulls you forward. Even if it’s a lure, it remains your only hope inside the anguished eclipse.
