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.
Watch on YouTube
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,

Sin & Siege Demo Arrives on August 3: Prepare to Rule the Hell!

Greetings from the dark depths of Hell!
Your appointment as the New Manager of our Infernal Branch is almost official. The Infernal Bureau has signed the decree: the Sin & Siege Demo will become available on August 3 at 13:00 UTC!
As Hell's Architect and Warden, your mission is clear: rebuild the Circles of Hell and defend the Heart of Darkness from the relentless Forces of Heaven.
Here's what your infernal job description looks like:
Capture the souls of sinners and extract Sin and Soul Fragments — the essential resources that keep Hell's great machine running.
Breed worker demons, send them to gather resources, and oversee the construction of new buildings.
Expand Hell's infrastructure by unlocking and developing new Circles of Hell.
Train demon warriors, forge weapons, and build powerful defensive structures.
Master infernal magic and strengthen your arsenal of devastating combat spells.
Stand against the ever-growing armies of Heaven as they march to destroy the Heart of Darkness.
And remember, Heaven will show no mercy. The holy hosts will attack in waves, growing more powerful with every assault. Sooner or later, Hell will fall... and you'll have to begin again. Fortunately, every defeat is a lesson. And your accumulated Sin and knowledge will persist between runs, making your next infernal settlement significantly stronger.
Are you ready to face this trial? If you are brave enough to accept the contract, follow Sin & Siege and add the game to your Wishlist now! Don't forget to leave your notes for the Infernal Bureau in our Discord.
From the depths of Hell,
The Sin & Siege Team

Greetings from the dark depths of Hell!
The mill of suffering is slowly but surely grinding away, churning up the souls of sinners—and while it does, check out the trailer for the new rogue-lite strategy game Sin & Siege and join the playtest! You are the architect and ruler of Hell, and your main mission is to restore the circles of the underworld and protect the Heart of Darkness from the pious crusaders.

Here’s what awaits you in the game:
A unique gameplay mechanic where your main resource is sinful souls—arriving in unlimited numbers to your domain. Catch them and extract Sin and Soul Fragments, the key fuel that keeps the infernal engine running.
The Seven Deadly Sins—your greatest allies in rebuilding the underworld. Each sin powers a different branch of your economy: Greed helps you stockpile resources to the brim, Sloth gets the most out of your workers, Lust helps you multiply, Wrath ensures no holy warrior walks away unscathed after trying to undo your hard work.
Loyal workers—demons who will build and toil, sow and reap, create and train new demons, capture and torment sinners, and help you in your mission in every way imaginable.
Clashes with the Forces of Light—those who seek to seize and destroy the Heart of Darkness.
Take the reins before the mill of fate grinds to a halt forever.
Join the Sin & Siege playtest! Put your willpower and skills to the test, and become an architect whose name strikes fear even into the souls of the departed. We want to hear from you—share your feedback so we can fine-tune the infernal machine to perfection. Don’t let the flames of the underworld die out!
From the depths of Hell,
The Sin & Siege Team
