About This Game

“There’s no signal. No escape. Something down here stirs... And one of us is certainly lying...”

In the year 2042, what was supposed to be a routine research expedition on a remote island turns into a nightmare. An unexpected collapse traps you deep underground with six others—but something about this place isn’t natural. What begins as a struggle for survival soon twists into something stranger. Whispers echo in the dark, and as suspicion spreads, questions mount: Who can you trust? Why does the cave feel... alive? And was this truly an accident?

Advent: Dawn is an emotive sci-fi mystery visual novel that weaves psychological suspense, emotional storytelling, and mythological undertones into a branching narrative with multiple endings. Inspired by genre classics like Zero Escape, Ever17, and Steins;gate, this is a story-first experience designed for fans of gripping plots, high emotions and thought-provoking twists.

FEATURES:

  • Multi-route Structure: Your decisions guide the story, unlocking branching routes and multiple outcomes—all leading toward a climactic "True Ending."

  • Interactive Flowchart: Includes an interactive flowchart "map" that helps you revisit your choices to work your way through the cave and character routes.

  • Occasional Puzzles: Solve light puzzles woven into the environment and narrative to enhance tension and immersion.

  • Voice Acting: Partially voiced with optional voice-blip effects to accompany unvoiced lines, all synced with mouth animations for added immersion. Voice acting and voice-blips can be toggled and adjusted separately in the preferences menu.

  • Original Soundtrack: A fully original soundtrack from composer 'Caleb Coles'.

  • Mystery, Myth, Murder & Mind Games: Themes of identity, memory, and ancient symbolism are fused with a suspenseful sci-fi survival / murder mystery story.

  • Length: Standard read: 12-16hrs. Methodical read: 16-22hrs. Speed read: 9-12hrs.

Whether you're here for the heart, the tension, or the high-concept twists, Advent: Dawn invites you to descend—and decide.

WISHLIST NOW! Releasing late 2025 / early 2026.

*Developer's Note: Advent: Dawn is set in the same universe as The VII Enigma, but it is a standalone title—you don’t need to have played the previous game to enjoy this one. That said, fans of our earlier games can expect some tie-ins and Easter eggs along the way.

AI Generated Content Disclosure

The developers describe how their game uses AI Generated Content like this:

We became aware one hired artist used image generation for background reference that were then repainted and shaded by hand. The MAIN backgrounds, created by a different artist, were made ENTIRELY WITHOUT generation.

No AI was involved in ANY other part of the game’s development. This means no AI of any form was used in the creation of the game’s character sprites, CGs, writing, scripting, coding, music, main backgrounds, or UI.

Mature Content Description

The developers describe the content like this:

Contains mature themes, including injury, death, and intense scenes that may be distressing for younger audiences. Recommended for mature players.
