The game I’m introducing today taps into something that always holds a strong appeal for players: the ability to build your own dungeon and defend it against fearless adventurers. That’s exactly what happens in Underground Security Inc., a roguelite strategy dungeon defense developed by Willis, the solo creator behind KRNK Studios, which combines base-building, tower defense, and roguelite mechanics.
The game puts players in the role of a dungeon master managing minions, constructing traps, and fending off adventurers—all while striving to generate profits for demanding shareholders.
Set in a world where dungeon security is a corporate enterprise, Underground Security Inc challenges players to balance expansion and defense. During the night, players assign their minions—ranging from skeletons to necromancers—to perform critical tasks like mining, constructing traps, and conducting rituals.
By day, the dungeon is besieged by adventurers seeking treasure, requiring players to deploy their defenses strategically. With over 75 different minions across five clans, numerous building blueprints, and ancient tomes that provide game-changing effects, the game offers deep customization and replayability.
As the dungeon grows, so does the challenge, with stronger adventurers and legendary bosses pushing players’ strategic and planning skills to the limit. Success is measured not only by surviving these encounters but also by maintaining financial stability—failure to pay dividends spells the end of a run. A demo is expected in the coming months, while the release will happen sometime in Q4 2025. Below is an overview of the game via Steam, screens, and an announcement trailer.
