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
