Last Fortress: Underground

The largest group of survivors, Castle, has been destroyed.

It was once a symbol of hope in the post-apocalyptic world, but it now meets the same end as the others. A handful of survivors were able to flee into the desolate woods amidst the mayhem.

As the leader of these survivors, you discover a strange building sticking out of the ground while running from the zombie horde that completely demolished your previous haven. You choose to seek sanctuary in this structure since you are short on supplies and have few other options. Your fight for survival in this zombie-infested world officially starts now.

DESIGN & BUILD YOUR OWN SHELTER

Add more amenities to your bunker, like the Satellite Nexus, power generators, mission control, etc. You can arrange the shelter however you want!

SURVIVORS AND HEROES

Every hero and survivor has unique life skills that enabled them to endure in the post-apocalyptic world. It's up to you to use each profession's skills to its full potential, from cooks to doctors to engineers to scientists to miners to soldiers.

COMPOSITION AND SYNERGY OF THE TEAM

Bring together a diverse group of heroes, each with their own special skills and personality. Create your ideal team composition to assist you in overcoming even the most challenging circumstances.

GO FORWARD IN THE WILD

Leave the refuge and explore the wastelands in search of useful resources. Create camps that will serve as resource centers and forward operations bases. But watch out! Any time, a zombie onslaught could happen!

FORM ALLIANCES WITH FRIENDS

Why not fight with friends if fighting by yourself is difficult? Join or start your own Alliance to destroy those bothersome zombies with allies! Accelerate one another's technological research and construction efforts to aid allies. In either case, it's a win-win situation! Now, it's all or nothing! Commander, go forth and begin your journey!
