About this game

Defenses on the surface have fallen, and the Zombie Tide approaches.

A sudden calamity plunges civilization into ruin. Zombies rampage the surface, and survivors are driven underground. As the Shelter's Commander amidst the chaos, you must restart a system that has become overrun. Restore electricity, repair defense lines, organize production, and lead survivors against the zombie tides to seize back our hope of survival.

This isn't a ready-made haven, but a shelter on the verge of collapse. The power generator is overloaded, resources are short, the entrance is damaged, and zombie tides continuously strike the defense lines. Each construction, deployment, and exploration determines whether the Shelter will survive the next crisis.

Will you be able to lead the remnants to survival and re-ignite the torch of civilization? It's time to stand up and fight the last fight!

Game Highlights

Reboot the Underground Shelter
Repair the power generator, coal mine, central control room, and other key facilities to bring the underground system back online. Devise strategies for resources, food, steel, and space management, gradually expanding your very own post-apocalyptic base.

Deploy Defenses and Resist Zombie Tides
Place defense towers to form defense lines on the surface, research and develop blueprints, build up firepower, and meet wave after wave of zombies head-on. As more and more powerful enemies appear, only by continuously upgrading the defense line can you keep the Shelter's entrance protected.

Receive and Manage Survivors
Send out signals calling for aid, take in survivors, assess their skills, and dispatch them to positions in stations like farms, dining halls, and factories. Monitor their health, mood, and satisfaction to not only let the shelter survive but to reestablish order.

Recruit Heroes and Conduct Deep Explorations
Heroes with various unique skills will join your team. Penetrate deep into zombie nests and abandoned facilities, searching for supplies, clues, and blood serum samples. Abandoned and fallen shelters hide dangerous experiments as well as keys to improve the future.

Repair the Radar and Search the Wastelands
Once the radar is restored, your underground shelter will no longer be cut off from the outside world. Locate distress signals, provide aid to squads of war vehicles, train armies, and clear away the surrounding threats, gradually taming the broader wastes.

Form Alliances, Compete, and Expand
In the wastelands, some Shelters may become enemies and others, allies. Prove your might and forge relations abroad, joining Alliances, and competing for resources and withstanding threats together with other survivors.

The surface has fallen, but humanity has not yet failed.
Now, Commander, reboot the shelter and fight on the final defense line.
Build a Fortress of Steel and Resist the Unending Zombie Tide.

Sorry for the unpleasant experience you had. In the early stages of the game, in order to better explain the plot background and related settings, the dialogues and tutorials may make some players feel long and boring. We fully understand your thoughts and look forward to hearing your suggestions! Our email address is: SD@camel4u.com .

Great game. But constantly being showed what to do is ridiculous. Cut back on that and it would be better
