Lead a determined group of survivors through the heart of a crumbling city, tasked with building a resilient colony amidst constant danger and chaos. As their leader, you will manage essential resources like food, wood, and scrap metal, scavenged from perilous locations across the map. Your colony's survival depends on the effective construction of crucial buildings and defences, from basic shelters to sophisticated guard towers and deadly flame turrets, each offering strategic advantages in the face of relentless attacks.

In this autonomous survival environment, NPCs take on roles as workers or fighters, moving independently but influenced by the base's expansion and designated waypoints. Place beacons to mark vital work zones, defence points, and areas for further development, allowing NPCs to autonomously fulfil their roles. Workers focus on building, gathering, and maintaining the colony’s internal needs, while fighters protect the base from the undead hordes and opportunistic raiders who threaten its survival.

As your colony grows, you gain access to specialized buildings that help manage critical needs like hunger, sleep, and entertainment, ensuring your survivors maintain high morale. A carefully balanced happiness system affects productivity and the colony's overall resilience. Constantly monitoring and addressing the needs of your community becomes crucial as population levels rise and the colony expands into new areas of the map, opening access to rare resources and previously inaccessible buildings.

Closer to the end of early access, upgrades become available, providing powerful enhancements for workers and fighters. These upgrades come not just from the buildings you construct but from unique buildings that can only be accessed by controlling specific areas on the map. Securing these critical zones unlocks new capabilities, fortifying your colony's defences such as the punishing Flame Turret and equipping fighters with the strength to endure.

The long-term goal is survival. But when the colony reaches a certain size, your people uncover an ancient bunker – a possible sanctuary or a cache of lost technology. With this discovery, your mission shifts: breaking into the bunker becomes your final objective. However, this challenge requires careful planning as you must maintain your defences against increasingly intense waves of enemies while your fighters work to breach the bunker.

Every decision you make shapes your colony's fate in this strategic survival management game, where perseverance, resourcefulness, and tactical thinking are your strongest assets. Lead your survivors, build your legacy, and see if you can survive the end.
