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!

Lots of Bugs

This game is actually good, but like most mobile game ads the game is COMPLETELY different from the ads. However, I was surprised to see this game was actually good. It reminded me of the mobile game “Fallout Shelter.” So, if you like Sims and zombies this is the game for you. The reason I won’t give it 5-stars is because there are a LOT OF BUGS. I usually find myself having to restart my game because things aren’t working the way they are supposed to. As an example, you have to use gopher traps in your bunker to get meat. You can upgrade these traps to get more than one gopher rather than just one at a time. Eventually when the trap gets full. You have to get one of your heroes to get the gophers out of the trap. Whenever I try to get the gophers out the trap, my heroes don’t ever go to the traps. I am constantly trying to click the buttons to bring my heroes to the trap, but it just doesn’t work. I have tried restarting my game (and even my phone). Sadly, it didn’t work. I hope this bug gets fixed so that I don’t run out of food so easily and find one of my residents gone after only 40 minutes out of the game.

Pay to Win struggle

I absolutely love this game and have been playing it everyday for a month straight ever since I first downloaded it. But as I play more and more it only gets harder and harder to compete with people who have spent any amount of money on this game. The robot that collects all your resources from your base would be insanely helpful in the progression of a base, but the fact you have to pay ten dollars for that is a little ridiculous to me. You can also get a 4th work station, which is insanely helpful in the development and quick progression of a base. But you have to pay five dollars for that as well. These are just a couple of instances where you have to pay in order to come anywhere close to keeping up with your competitors, like I said this is a great game, but I feel adding these features just to be told you have to pay to win is a huge smack in the face for anyone who actually wants to be able to have fun without spending money on a mobile app. Even at least making these things a little more affordable for everybody would help the problem, 99 cents is a more than reasonable price for any add on In this game. If you ask me 5$ and even 10$ for add ons that are Almost essential to developing your base and keeping up with your opponents who have that kind of money to spend, is flat out ridiculous. Thank you and I hope change comes soon, for the future of this games sake.

Dear player: Hello, I am very sorry to give you a bad experience. Our game provides a lot of ways to play, and some players don't spend a lot of money in the game, but they also develop very well. As long as you have a certain amount of patience and master some gameplay and skills, you can also develop well in the game like other players. I will give you a little suggestion, you can try it: 1. Actively participate in the daily tasks in the game, and complete the tasks to obtain development resources and game props; 2. Join an active alliance, participate in alliance activities together, and work with the alliance Development; 3. Use game props appropriately to help and protect yourself. There are more tricks and ways to play in the game that you can explore with your allies. You can contact us directly in the game (click on the avatar in the upper left corner, then click on customer service help), or you prefer to communicate with us by email (, both of which you can contact us in any way. Remember to describe your problem in detail, submit account information, and submit relevant screenshots if possible. Happy gaming.

I wanted to give more stars

So why didn’t I? Because I wanted a game to play as I wanted by myself if I wanted. This game for all it’s cool gameplay eventually forces you into an alliance to survive. It’s not really an option not to. That instantly destroyed any enjoyment I had from the game. I had advanced as far as I could without losing my city shield. And once down I have to fight off both zombie hordes and other players. I don’t want forced social interaction. I don’t want strangers raiding my base and wasting whatever time and resources it took to build it up. So when I could advance no further without having to ally myself or be raided I deleted the game. It is obvious that despite all the hard work in developing the game, its creators have no interest in solo players like me. Too bad.

Update. The developer responded in part by telling me it was a dangerous world and alliances were popular. Apparently I was not clear when I said that being forced into an alliance was a “feature” that I did not want or enjoy and since I prefer solo play. Hence I deleted the game. Don’t tell me that I am wrong for not wanting social interaction dependency in a game…it is fine to have if I want it…but not as a must have to play option. Nor do I want any being raided by other players. Perhaps I wasn’t clear on that either. No pvp for me. So if the developers want to develop solo friendly options I will be back. If not then bye bye Last Fortress.

Dear Commander: Hello, I am very sorry to give you a bad experience. Your feedback has been sent to the developers and we believe they will take it into consideration as they update and optimize the game. In the apocalyptic world, there are many dangers, and it will be more profitable to develop with the alliance. If you are frequently attacked by other players, you can try to protect your shelter with in-game items. If you encounter any problems in Doomsday World, or have any suggestions, please contact us directly in the game (click [avatar] in the upper left corner, click [customer service]), or contact us by email ( ), describe your problem in detail, and submit your account information. If possible, please submit relevant screenshots. We will read it carefully and get back to you as soon as possible. Happy gaming.
