Lead the last survivors after the Cataclysm as a corrupt world seeks to destroy all that remains of humanity. Build fortresses brick by brick, designing towering, intricate structures of wood and stone to defend against waves of Horrors attempting to overwhelm your group of survivors. Command powerful units in their staunch defense, coordinating their varied capabilities as you race from gap to gap. Lead raids into the unknown to secure vital resources needed to increase your military power and construction capabilities while holding your ground against the ever-increasing onslaught – siege after siege, night after night.

Far from the relative safety of the Last City, your citadels and outposts stop hordes of Horrors before they can strike at the heart of humanity. Build impregnable fortresses in multiple biomes using an intricate construction system that allows you to design your defenses with complete freedom and strategic creativity, adapting your plans to the environment around you. Take advantage of natural bottlenecks, altitude advantages, and local resources as you strategize for each night’s attack challenge.

  • A highly modular building system allows you to design your forts exactly how you want: one piece at a time, with blueprints you’ve designed beforehand, or using community creations shared by other players. Use your hard-earned resources to build structures that grant access to previously unreachable parts of the map, or build fortifications that deny access to Horrors and provide your troops with safe vantage points.
  • Build cheaply and quickly with wood, or set up quarries and use durable stone to better resist attack. Keep an eye on structural integrity and load-bearing columns, as falling pieces will kill friend and foe alike, often creating unique opportunities to crush numerous enemies with cleverly placed vulnerabilities.
  • Adapt your fortress to growing needs as you acquire new tools and expand in an attempt to secure all the resources necessary to sustain a powerful defensive force. Optimize the path from resource depots to your warehouses with well-placed structures and use rooftop construction to make the most of your limited space.
