Tips & secrets

Keep an eye on the cafeteria — satiety affects residents' mood. If mood drops below 60%, people will start leaving the shelter, and you'll lose workers.
Don't skimp on staircases — workers use them to move between floors. If you place staircases wisely, resources reach the cafeteria and warehouse faster.
Level up one APC first — if you're not spending much, invest in your first APC and main squad. It's worth building a second squad once your main heroes reach at least level 70. You can save your main squad in each APC and deploy it if your primary vehicle runs out of durability.
Don't rush Solari heroes — early in the game, leveling them up gives almost no benefit. Focus on them once you're earning 5,000 memento coins a day and your buildings have reached level 16–20.
Research the Plunder technology — it gives 5,000 Z Coins a week, and early on Z Coins are scarce. If you spot Z Coin mines on the map, mine those too.
Stockpile resources before Alliance Trial — this event starts in 2–3 weeks. About a week before it begins, start saving up speedups, recruitment tokens, and diamonds. If your alliance is inactive, feel free to switch to another one.

Frequently Asked Questions

What is Last Fortress: Underground about?

It's a survival strategy game set after the fall of the Castle, the largest community of surviving humans. A small squad flees from a zombie horde into the wasteland and sets up a new shelter in a strange structure jutting out of the ground.

How do you upgrade the shelter and why do you need residents with different professions?

The shelter grows step by step: generators, satellite communications, a mission control center and other facilities appear, and the player chooses the layout themselves. Among the survivors are cooks, doctors, engineers, scientists, miners and soldiers, each with their own skills. Placing them in the right spots makes the base run noticeably better.

Can you play together with other players?

Yes, you can join an alliance or build your own. Allies team up to wipe out the undead and speed up each other's construction and research.

Description

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!
