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!

This game is terrible. Before you start playing each day, you need to go into the controls section of the game and hit the repair button. Just so you can get your proper updates. Then the bugs in the game you will have. I have the research bug, so I can't complete some research sections in the game. The customer service has tried to fix the problem over months but has given up so tough luck. Now, before server maintenance, I used an 8 hour shield. Usually, it's an hour maintenance,but

The game is fun and entertaining but there are a few things I would change like you have Auto Cook but you don't allow them to Auto Collect the food/water add this please it would help keep the survivors from leaving. For some reason you can get people but they don't do anything. you have like 3 people who actually work and everyone else just sits there you cant assign people that you save any work. So far that's it the game is a good game overall

after years of seeing ads for this and thinking it was just another one of those clickbait games I've finally downloaded it and can genuinely say I'm really enjoying it so far! it took me about 20 minutes to rescue Alisa and at 45 minutes in I'm already working on a level 5 control center. if you're a fan of games like Fallout Shelter this is ABSOLUTELY worth trying!
