About this game

Castle, the largest community of survivors, has fallen.

Once a beacon of hope in the post-apocalypse, it now shares the same fate as the rest. Amidst the chaos, a small group of survivors managed to escape into the barren wilderness.

You are the Commander of these survivors. While escaping the zombie horde that utterly destroyed your last sanctuary, you come across a strange building jutting out from the ground. Low on supplies and left with little options, you decide to take refuge in this building. So begins your campaign of survival in this zombie-infested world.

【BUILD & CUSTOMIZE YOUR SHELTER】
Expand your shelter with numerous facilities such as the Satellite Nexus, Power Generators, the Mission Control, etc. Design the shelter’s layout whichever way you like!

【HEROES AND SURVIVORS】
Every hero and survivor possesses special 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!

【TEAM COMPOSITION AND SYNERGY】
Assemble a diverse team of heroes, each with their unique personalities and abilities. Formulate your favorite team combination to help you conquer even the most daunting of situations.

【VENTURE INTO THE WILD】
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! Zombies could attack at any moment!

【ESTABLISH ALLIANCES WITH FRIENDS】
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!

Fun addictive and can be too expensive for most. It's like a slot machine that gives you nothing in return except a shot of dopamine when you click a freaking button. Oh, and wait times.. When getting into the later stages of an upgrade, plan on waiting 2 to 4 months for something to lvl up. Unless?? You pay money and lots of it. There's talk that players are spending thousands to get the newest character or thing upgraded to a max lvl. Wanna reiterate.. THOUSANDS!!! But fun. Be responsible.

when the starting to play this game initially it was rather fun, but after a few hours the amount of bugs that I've run into that prevent me from moving forward in the game really make me regret spending any money on it so far. currently I am stuck in that I cannot reclaim the water filtration plant, I can't get rid of exclamation points indicating there are actions to be taken in the game and the list goes on.

Losing power with no attacks or changes on my part. Second time today. I do pay and play. Don't download. There is a major problem. Update: the devs have been working very hard on this game. They have added great content and fixed all of the bugs that were a major problem. So far this is the best game of it's type I've played (over 12 years)
