About This Game

Black Equation: A Branching Dark Fantasy & Sci-Fi Visual Novel.

Welcome to Highgard.

Created by a solo indie developer, Black Equation is a uniquely vast and deeply non-linear interactive fiction adventure. This isn't just a story; it's a living tapestry woven from your choices, offering two distinct playable paths within one epic saga.

Explore Highgard, shaping its destiny through profound choices and unique experiences. Will you unravel biological secrets in a sci-fi quest of scientific discovery, or delve into epic fantasy through fragmented memories of a colossal creature? Every decision matters, affecting the narrative and leading to multiple endings.

Prepare for a journey where every choice matters, and every secret discovered reshapes your understanding of both science and destiny.

Dive Deeper into Highgard in Black Equation, a story-rich text-based game with dynamic narrative and consequential choices.

    • Journey: Delve into a realm of scientific exploration. You will meticulously examine the remains of a colossal creature, unraveling its biological secrets through precise observation and deduction.

    • Gameplay: This section unfolds like a scientific journal, demanding your intellect to navigate medical/anatomical procedures.

  • Part 2: Echoes from Within

    • Journey: Embark on an epic fantasy adventure through Highgard, a narrative tapestry woven from the creature's own fragmented memories.

    • Gameplay: Your path here will be shaped by profound choices, guiding characters through a world of magic, intrigue, and personal sacrifice. Every decision dramatically influences the unfolding story, as choosing one path may lead to unseen events and skipped narrative fragments in others, urging you to explore every possibility.
