Mature Content Description

The developers describe the content like this:

"The Call of Darkness" is an Adult Visual Novel centered on story, adventure, and rich character development within a sci-fi setting infused with Lovecraftian and fantasy elements.
The base game features nudity, horror themes, non-sexual violence, and a small amount of gore—depicting dead bodies, otherworldly creatures, and primarily psychological horror.
While the game includes romantic and sexual content options, these are fully contained within an optional, free DLC that unlocks the full adult experience. This design ensures that players can enjoy the core narrative without sexual content if they prefer. The DLC will be available at launch.

About This Game

The Call of Darkness is a story-driven adult visual novel set in a distant sci-fi future, where you play a war veteran on the brink of a new chapter. The embers of a devastating conflict that nearly split humanity are still warm, and as the newly minted Captain of a sensual, motley crew, you’re ready for a more laid-back adventure.

But a prayer whispered in those dark days of war has stirred something Ancient — a hunger from beyond the Darkness, reaching and creeping into your dreams. It has plans for you, and it doesn’t take no for an answer. Its messenger, born from your deepest desires, is both gifted and a guide—but she needs your help before you can face the horrors to come together. Survival may exact a price that may shatter your very soul—as your past collides with a future far beyond what you imagined, and every victory demands a sacrifice.

A Dream Given Life

The nameable envoy from your new patron, given life from longings deep within your own heart and mind.
Devoted and intimately familiar with your innermost thoughts, her innocence conceals a darker side—one easily overlooked, but not to be ignored.

Welcome to the Antares! She is a decommissioned Earth Gov destroyer, now in private service—and your new berth as her Captain. You have just been assigned to her by H.P. Industries and have yet to meet your rambunctious crew.

These are only some of the major characters you get to know, but several more will join you just in the first Arc.

Pella
The one you left behind when you were drafted to fight for Earth in the Mars Rebellion.

Fiery, passionate, and tenacious—

you thought letting her go was the noble choice to protect her,
but the past has a way of catching up.
