Added a new code!

The zombies have taken over the world, and there’s little keeping the living ones from joining their ranks. Except for intricate underground strongholds, where they have to live, farm, research, and ultimately fight back against both the living and the dead. This is the world of Last Fortress: Underground, a mobile strategy game with gacha elements in which you can build up your stronghold, heroes, and troops, then send them out to explore the world, fight other players, and more.

In Last Fortress: Underground, you can redeem codes to earn various rewards, such as resources, boosts, and other goodies. These codes can help you get a head start if you’re just starting or help you get over a hurdle if you’re already playing the game.

Why are Last Fortress: Underground codes not working?

There’s a possibility that some codes you entered might not work due to several reasons. Check that you’ve entered the code exactly as it was listed — no extra characters or spaces, and that all caps match the code. To avoid typos, you can just copy and paste the code from the above list. Also, codes are usually available for one use only, so you won’t be able to redeem extra rewards multiple times. Lastly, some codes may have expired and have been added to the list of expired codes.
