SinSiege
SteamAbout SinSiege
SinSiege is a wild fusion of strategy, action, and survivor-style chaos — where every wave pushes you to evolve your strategy and every hero adds a new twist to the holy war. Whether you're here for the depth or the devilry, one thing's for sure:
Hell isn’t ready for Adamkind.
Strategy. Survival. Sanctified mayhem.
Hell has declared war on humanity's last outposts — embassies built deep in the inferno to keep a fragile peace. But now, the Seven Sins rise, and the flames of diplomacy are burning out fast.
The world’s final hope? A decision from on high: send the Earth's mightiest heroes.
All of them.
Welcome to the Consulate of Adamkind, humanity's last foothold in Hell — and your battlefield.
