The highly anticipated Siege Update for the Steam version of Dwarf Fortress has been released on 2025-11-04, offering players significant changes in gameplay dynamics. Bay 12 Games has introduced more complex invader behaviors, making this the first major update since the Steam launch.
Enhanced Invader Dynamics
The update brings a fresh perspective to invader tactics. Goblin hordes now deploy siege equipment such as battering rams and trolls. These invaders are organized into strategic roles which include charging, hanging back, and ambushing. Additionally, they can now path around dangerous areas, providing a greater challenge for players. Siege engineers among the invaders can construct floors, stairs, and even mine underground to attack fortresses from below.
New Defensive Tools for Players
Alongside the challenges posed by invaders, players receive new options to enhance their defenses. The update introduces a rapid-fire bolt thrower, along with more powerful catapults and ballistae. Traditional defensive strategies using traps, water, and magma remain effective, though players must adapt as invaders can now free trapped allies.
Compatibility and Settings
The update is designed to integrate smoothly with existing Dwarf Fortress saves, compatible with all but a few specific features. For those who prefer less complex gameplay, the new enemy behaviors can be toggled off entirely or customized to suit individual preferences.
