Build and expand your underground fortress to survive the zombie apocalypse!

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.

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!

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!

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.

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!

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!

Improvement needed

After much review of this game there are some small issues and large issues that should be fixed to improve overall game play. Let’s start with the small issues the game interface slightly buggy and lags even with the best equipment. This can be fixed. Pay to win plays strong in this game and the rates for upgrades are far above what similar games of this caliber are charging. This can also be fixed by dialing it back or increasing game play value. At the current value and game play you will have difficulty retaining players. Also, listen to the other reviews, resources that are purchased should not be available to another player if they choose to raid the customer paying for that upgrade. Those practices will break a customers trust in a product. The last major issue to look at is alliances. If you investigate as I did you find that there is a central alliance across all levels of this game. This alliance uses slightly different names but part of a larger group. This group only accepts people of a certain demographic and preys on others that are not in that demographic. In a time where inclusiveness is a major issue this will cause a product to hemorrhage potential customers at an alarming rate. This is also a simple fix that many other more popular games have addressed by regional grouping. I do this for a living for many other companies and normally charge for this type of advice, but this is a freebie. Take it or leave it that’s up to you.

Has a few issues

So the game is actually really fun and way more in-depth then you might think but it does come with a few issues. First of all developers if your going to advertise this game do not lie to people. Your ads for this game do not show ANY of the actual gameplay that’s in this game. It’s a very bad thing for new players to be shown an ad about a game and then they play it and the game is COMPLETELY different then the advertisements. There is a few times where I’ve noticed the game slows down and just straight crashes. But not very often usually only happens when a lot of stuff is happening on screen. The game is a fortress builder/multiplayer base attacking game and it does do a pretty good job at it. My other issue is that it’s insanely hard to pull good heroes. Most of the time I’m getting straight garbage. Edit: It is nice to introduce more things but I would personally fix older things, bugs and glitches before releasing new events. At this point your just adding even more bugs and glitches. Also fix your preview section on the App Store. Only 2 pictures and none of the videos show the actual game. 2 pictures….that’s sad. Now sure what game the other pictures and the videos are of but it’s not this game. Take pride in your game. Show actual pictures and videos of your actual game and gameplay. That will draw more people in.
Edit: sorry developers but it’s true 🤷‍♂️

Hello dear commander, you may have misunderstood. The advertisement expresses the core experience of the game: "Apocalyptic Realistic Wasteland, Underground Refuge and Survival", you can freely build underground shelters in the game, operate the underground world for leisure, or you can Fight the zombies in the doomsday and take Eden with your allies. It is recommended that you do not blindly upgrade heroes in the early stage. First of all, you need to see which camp has more heroes and higher quality. The same camp will have attribute bonuses in the team. In addition, you can take a look at the achievement tasks in the lower left corner of the game, which can not only guide you to develop quickly, but also get a lot of resources and recruitment points. Regarding the crash of the game, we will continue to optimize it in subsequent versions, hoping to bring you a better game experience. Finally, I hope you will continue to support us and have fun!

Not bad, but woke annoying aspects

I’ve been playing for several months now. As expected the pay-to-play/win players will ALWAYS dominate! HOWEVER, my biggest complaint is the game-related POP-UPS!!! You touch a tile, POP-UP (to tell you about the tile). Win an award, POP-UP (tell what the award/prizes WERE), upgrade a building (POP-UP) to tell you what the upgrade improved. A LOT of the POP-UPs say “click anywhere to close”, but you REALLY CAN’T UNTIL THAT POPUP FINISHES FLOURISHING EVERYTHING YOU WON!!!! THEN, YOU CAN’T JUST CLICK ANYWHERE, YOU MUST CLICK SOMEWHERE!!!

When players are waiting days for an upgrade, we don’t have time for the MUNDANE POPUPS THAT HAVE BEEN SEEN SINCE DAY ONE!!! Instead of popups, send us silent emails - if we’re interested we’ll read them!!! OTHERWISE, THE PRIZES/REWARDS BECOME MUNDANE/REPETITIVE THAT SITTING THROUGH THEM IS A TOTAL WASTE OF TIME!!

I’m not talking ads, I’m talking about normal game-activity popups that should have end back at level 6 (or sooner)!!! If people loved popups, people wouldn’t be complaining about popup ads on websites!!! These aren’t random ads popping up in game, they’re “YOU CLICKED TO SEE WHAT YOUR INGAME REWARD WAS” popups!!! SEND EMAILS!!! GET RID OF THE COMMON/DAILY-repetitive popups! I CAN FINISH COLLECTING CHESTS AND SEE HOW MANY acquired AFTERWARD BY LOOKING IN INVENTORY!!!! After level 4 ENOUGH WITH THE CONSTANT POPUPS (unless it’s something new/never seen before)!!!
