The largest community of survivors, Castle, has fallen, leaving the post-apocalyptic world in chaos. A small group of survivors managed to escape into the wilderness, and you are their Commander. While fleeing from the zombie horde, you stumble upon a strange building and decide to take refuge there. This marks the beginning of your campaign for survival in a world overrun by zombies.

To survive, you must build and customize your shelter with various facilities such as the Satellite Nexus, Power Generators, and Mission Control. You can design the layout of your shelter however you like. Every hero and survivor in your team possesses unique life skills that helped them survive in the apocalypse. From chefs, doctors, and engineers to scientists, miners, and soldiers, it’s up to you to effectively utilize their skills. Assemble a diverse team of heroes, each with their unique personalities and abilities, and formulate your favorite team combination to help you conquer even the most daunting of situations.

Journey outside the shelter and scavenge for valuable resources in the wastelands. Set up camps to act as forward operating bases and resource points, but be on guard as zombies could attack at any moment. Fighting alone is hard, so why not fight alongside friends? Join or create an Alliance and exterminate those pesky zombies with allies. Assist allies by accelerating each other’s constructions and tech researches. It’s a win-win situation either way. It's all or nothing now! Go forth, Commander, and embark on your adventure!
