Take command of the last bastion of humanity. In Last Fortress: Underground, you must dig deep to expand your bunker, assign survivors to vital roles, and develop technology to survive the zombie apocalypse. Explore the overworld map to rescue others and scavenge for supplies, all while forging alliances with other players to dominate the wasteland.
Dinsun Expert Review
Our Expert Score
Last Fortress: Underground is a compelling mix of Fallout Shelter-style base management and a modern mobile 4X strategy game. The 'ant farm' view of your bunker is incredibly detailed; watching your survivors move between the generator, the kitchen, and the laboratory makes the base feel alive. The transition from the underground management to the overworld exploration provides a nice change of pace.
The game excels at making you care about your 'Heroes.' Each survivor has a specific role, and building the right team for scavenging runs is vital. While the late-game does lean into the typical social/alliance warfare seen in games like Rise of Kingdoms, the early to mid-game survival management is some of the best in the genre. It captures that desperate 'one more resource' feeling perfectly.
Features
Detailed bunker building
Hero collection and leveling
Alliance-based warfare

Explorable wasteland map
Tips & Walkthrough
Place your Power Generator near the center of your base to minimize the travel time for workers. Grouping related facilities, like the Diner and the Farm, streamlines your resource production.
Gameplays
Combine heroes from the same faction to unlock powerful combat bonuses. A well-balanced team with a tank, a healer, and high-damage dealers is essential for clearing zombie-infested floors.

Improvement needed
Sun Sep 04 2022 builditbetterAfter 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.
Last fortress
Thu Nov 16 2023 thumbtack victimThis game is addictive and fun but expensive it’s a lot of fun when you find a good alliance but there are still some small problems like the lack of games at the bar that cost 50 dollars or certain events like the 1 with the pick axe forgot the name but it tells you after the event all of your completed pieces of the highest level you can save but all other pieces will disappear I spent my money saved pieces trying to wait for the next time the event rolls around to have more pieces to make better purchases but they have all disappeared after the event ends like 3 times now that’s false advertisement also getting fortress skins are impossible even through purchase and when they finally come around they cost probably 500-1k usd in purchases to obtain absolutely to expensive for a skin that gives you no ability also there are no timed team attacks so smaller players can’t take down stronger players even in a rally because they attack solo 1x1 with timed attacks as long as your attack arrives to the enemy while your alliance member is attacking both your armies with attack together up to like 5 members at a time meaning if my cp is 10 million and a 5 mill 3 mill and 4 mill send attacks that arrive at the same time there army will be 12 million vs my 10 million that will eliminate the bullying from stronger players and give smaller players more hope and give them an overall better more fun experience
Fun game but expect to spend money
Wed Oct 09 2024 riariabia123I have been playing for around a year now and I can 100% say you will not get very far if you aren’t spending money or join a top 3 alliance (which means you need to spend money to be able to join). Being in an alliance does mean you will get more daily rewards but it’s definitely not enough to keep you strong in this game. Expect to be attacked by high spending players and you can’t do anything about it. I have spent a considerable amount of money to get to the strength I am but I am still not as strong as I could be and still deal with bullying from stronger alliances. Everything in this game is a money grab. And in this economy I think the pricing of things in this game is absolutely ridiculous and egregious. $100 for 10 car parts? High spending players spend at least 10k minimum on the game just to give an idea. You can get more accurate numbers on the subreddit for this game. It’s enjoyable but as you progress it doesn’t get very fun unless you are spending money. The developers responses have all been the same that is how I know they don’t really care about the free to play or low spending players. We are in one of the worst recessions and a game that is supposed to be a stress reliever in these times is causing people to go bankrupt! I think it’s very predatory of the developers. They are well aware that this game is not easy for people not willing to spend money but they don’t care! So play with caution.
Almost perfect but alliance should have more
Thu May 04 2023 For Christ sake fix thisA lot of alliances will work together and become Allies with one another and others will form NAP It would be nice if instead of having everyone turn up same color on the map, besides members of the alliance you’re in, other alliances that you have listed as allies or that your alliance have a NAP would come up a different color. That way you wouldn’t have to constantly check the alliance page to see who is a friendly and who isn’t. Another thing that I think should be introduced is the for alliance members to be donate or provide other members with resources. For example, say I am upgrading my garage, but I’m am short on iron. A member of my alliance could simply give me the material I need in order to upgrade that facility. Not only will this increase player interaction, but it gives a Members that can’t afford diamonds an alternative route to still be able to upgrade their base and stand a chance in this game, especially in later seasons. Plus in almost every single apocalypse game or story trading is like one of the main methods between different civilizations, and the fact that we’re able to trade with the helicopter merchant is not really realistic because any real Apocalypse situation different societies were definitely be trading with each other. Alliance member should also be to trade gear with each other and give members titles or nicknames. For instance a player that often scans the map and shares locations of possible threats or resources couldn’t receive the title of lookout.
Has a few issues
Wed Nov 02 2022 SkeletonMan180So 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 🤷♂️
Unabashedly Pay-to-Win
Thu Nov 17 2022 Anonymous424242This game is unabashedly pay to win. On nearly every screen, there are “give us money to get more rewards or premium characters!”options. There is no way to effectively compete with the other players without spending a ton of cash. The devs will tell you that you can get a lot of resources for free, which is true. But you get only a fraction of that of paying players, which doesn’t solve the pay-to-win problem. If you didn’t have to interact with other players, this wouldn’t be a problem. But no, if you can’t get your base strong enough, you get raided and destroyed by the wealthy players. That leads to my second big complaint about this game. It is deceptive in its marketing materials, and doesn’t explain anywhere that the main feature of the game once you get past the introduction is player-vs-player combat, and alliance warfare. This is yet another game where you have a city in an overworld with a bunch of other players, manage troops, and send armies to attack zombies and other players/alliances. But they hide that. No screenshots. Nothing in any ads I’ve seen. They hook you with the interesting gameplay of exploring and building out your bunker. Then they throw you into the overworld where you have to shell out real cash or constantly get raided by other players. The early gameplay with exploring and building your bunker is fantastic. If the game was just that, I’d love it. But, unfortunately, that is not what this game is.
Fun “BUTTTTT….”
Thu Aug 18 2022 frusterated gamerGame is fun but if you don’t have 1000$ dollars to spend on it even more then don’t play it! I wish I handnt downloaded this game it is solely pay to play. And the so called deals aren’t even deals. Plus you’d think there would be benifits of getting higher chances for better hero’s if you do pay ya there’s not “ or any perks at all” if you pay ya not even that… I bought a 10,000 hero token pack for 100$ and only got 2 purples hero’s out of 110 chances the rest were white blue and green btw ALOT of white which are lame breakdowns. it’s just like gambling it’s exciting but after you made the purchase and got nothing at all for it you have buyers remorse. don’t get me wrong the game is fun and a good time killer when you are bored but it hooks you and sometimes even forces you to spend money the “bar” yeah if you don’t have that then momento coins to upgrade your hero’s is next to impossible. Also there is no soloing at all. If you try you get stomped by higher ranked alliances to farm your resources. even then I’m level 21 and high hero’s and I still get crushed. My alliance members get mad because I never join their fights well it takes 7 days to heal my soldiers and I die immediately when I try so I do my daily’s, prey on 19 or below soloists, and kill zombies! That’s about it. Sorry for the rant but if there’s no perks for spending money other than upgrading that should already be available I’ll probably delete the game and move on to something that’s actually free…
Customer Service; Dimensions; Unhappy
Tue Jul 02 2024 nebzifI’ve reached out to customer service about this, waited two days for an answer of “we clearly state our rules before every dimension yada yada yada” and copy and pasting a BOT RESPONSE you just close my ticket with no resolution. Now I am here once again stating that no where it says that you need to be the First Capture on a Key City for a zombie invasion to start. Maybe if you actually read what my ticket was ABOUT and looked at the screenshots PROVIDED you would see that there IS NO TIMER. We have had a key city for 3 days now “the timer for a zombie invasion starts immediately to start within 23 hours of capturing” THERE IS NO TIMER. I don’t know why I waste my time on this game when for the most basic assistance needed you give 0 effort. Once again my alliance is screwed because of something YOU DIDN'T STATE for the entire season on our first play through. It says “when an alliance first occupies the core city, the zombie countdown” MAYBE you should change it to When an alliance gets a *First Capture*. No one knew about this, even people who have played through Doomed Land. Don’t try to say I’m the stupid one for not paying attention to “the rules” or “the announcements” when I’m in EVERY SINGLE social media page, every single discord chat, even Instagram. I follow everything and took WEEKS looking for information on doomed land. If I could lower my rating more I could. I’m livid at this response.
