The Sin & Siege Demo is live on Steam: Rule Hell today!

Greetings from the dark depths of Hell!

If you're reading this scroll, congratulations. The Infernal Bureau has officially appointed you as the new Warden of the Underworld. From this moment on, the fate of the Heart of Darkness rests in your hands.

But before entrusting you with eternity in the Infernal Groves, we'd like you to complete one small trial first — the Sin & Siege Demo. It is now available on Steam.

To mark the occasion, the Infernal Bureau has prepared an official Demo Trailer. We highly recommend reviewing it before beginning your duties.

Your probationary period is strictly structured and divided into rounds. Each round consists of two phases. During the Development Phase, you'll expand Hell's infrastructure, assign demons to different professions, gather resources, and prepare your settlement for the next part. During the Defense Phase, you'll command your armies, protect the Heart of Darkness, and repel increasingly relentless invasions from the Forces of Heaven. You will have to withstand five such rounds.

To succeed, you'll need to:

  • Capture the souls of sinners and harvest Sin, the resource that fuels Hell's entire economy.
  • Breed worker demons to gather resources and construct new buildings.
  • Expand your infrastructure across every available Circle of Hell.
  • Train demon warriors, forge weapons, and strengthen your defenses.
  • Master powerful spells and unleash infernal magic against Heaven's armies.

Keep one thing in mind: defeating the Forces of Heaven won't be easy. Each new assault grows larger, stronger, and far more dangerous than the last. And failure it's part of the job. Fortunately, the Infernal Bureau has planned for that as well. Your accumulated knowledge and permanent progression will carry over from one run to the next, allowing each new attempt to begin from a stronger foundation.

We carefully reviewed feedback from all the Managers who participated in the playtest, drew conclusions, and made changes to the Hell-management routine:

  • Completely redesigned tutorial and onboarding experience.
  • Rebalanced and improved production chains and resource management.
  • Expanded the construction area.
  • Reworked, simplified, or replaced several gameplay mechanics.
  • Removed a number of unnecessary buildings and resources.
  • Updated the visual style while preserving the infernal atmosphere.
  • And many more improvements throughout the game.

Our thanks go to every Warden who shared feedback and helped shape Sin & Siege. Now you’re ready for the challenge! Download the demo and take the reins of Hell.

Be sure to share your feedback! The Infernal Bureau is always accepting reports and suggestions here on Steam and on our Discord. And don't forget to follow Sin & Siege and add the game to your Wishlist so you won't miss what's coming next.

From the depths of Hell,

The Sin & Siege Team
