An all-purpose, all-terrain truck serves as both mobile storage and zombie-clearing vehicle, but it needs to be repaired before it runs and continuously protected to keep it operational. Resources gathered around the map support the construction of a shelter that will face increasingly complex zombie waves — each enemy type with its own behavior and quirk. Catapults, flame throwers, and AK-47 turrets can all be built to hold the perimeter. Other survivors are out there and each encounter offers a choice: help them, trade with them, or betray them. The environment changes in response to how resources are collected and structures are built. The ultimate objective is not shelter — it is escape. Call in the evacuation when ready. Be prepared for what arrives when the call goes through.
