Story of Leviathan

In 2092, the world has already been reshaped. Decades have passed since the Progenitor meteor fell—bringing with it the greatest monsters humanity has ever faced: the Leviathans.

You play as a sailor—part cowboy, part pioneer—on the newest frontier. The ocean is more dangerous than anything on land, crawling with beasts that seem nearly impossible to kill. But where danger exists, there’s also profit, glory, and power. Carrying your father’s legacy, you chase the chance to become a legend.

After your last job goes badly, you’re forced to adapt. In the end, you discover a secret that turns your misfortune into the biggest treasure hunt the world has ever seen. To keep yourself alive, you’ll need to build a crew, collect information, and face the many threats determined to end you.

A captain’s crew is their life. And you’ve been given a crew of “beauties”—not just a pretty face, but partners who matter. Your romance choices and personal decisions directly influence your personality and role in the world. Your destiny is something only you can shape.

Changelog

Leviathan 0.4 Release

Leviathan 0.4 is now officially released. The update arrived a bit later than planned due to issues with the new UI integration, but the developer worked through it and brought the update together overnight.

Version 0.4 includes:

• 800 new renders
• 19,000 new words added to the script
• New music for every new scene



• A reworked SFX system
• A brand-new UI created by Pax

The developer describes 0.4 as their longest update so far—long enough that it took longer than all previous updates combined. While personal setbacks occurred due to college, the main goal of 0.4 has been to raise quality and professionalism to a level the creator feels confident about.

They also note that 0.4 is the first update that makes them feel Leviathan fully belongs in the conversation for polished, high-quality AVN content. This update ties together two arcs, expands characters, adds new developments, and introduces new characters. Feedback from earlier updates was reviewed, with many edits and adjustments made to earlier game content as well.

Support is encouraged. The developer invites players to join their Discord or Patreon if they’d like to keep up with future releases.

Player Comments

• Positive with reservations: “Good, but not too special.” Compliments the girls’ personalities and the overall story, but mentions sex scenes feel too short.
• Writing clarity: Some lines can be hard to understand at times, but it improves as the story progresses. Typos and abrupt narration shifts (from second person to third person) were also noted.
• Choices: There are good decision moments, but it can be difficult to tell what impact they truly have.
• Character art note: The protagonist’s torso looks emaciated until near the end of 0.4.
• Overall effort and worldbuilding: Praises the presence of lore and a real story, rather than a basic setup where someone stumbles into a harem. Notes a diverse cast of attractive love interests and a protagonist with a backstory and earned skills.
• Story hooks: The reviewer wants more—especially about Leviathans, how they evolve, their origins, and the suggestion of factions within them.
• Writing quality: The final note praises the writing, clarifying that they mean the actual writing process rather than only the story itself.
