About This Game

Underground Security Inc features a blend of tower defense, autobattler, and roguelite gameplay. Expand your dungeon by night and defend against waves of heroes by day.

Create new paths, build and upgrade traps, deploy minions, and cast powerful spells to stop heroes determined to "liberate" the chest at the center of your dungeon. Adapt your defenses to different incoming waves and put them to the test against increasingly powerful heroes, including legendary champions.

Carefully select minions to recruit and build your strategy around their unique capabilities. Each minion comes with its own stats, traits, and skills, allowing for countless tactical possibilities.

Assign your workforce wisely. Will they help mine for precious resources, construct traps, or stand on the front lines to defend your dungeon? Every assignment matters, but don't worry, your minions return to your hand once they've completed their tasks, letting you adapt your strategy as the run unfolds.

Upgrade your minions with powerful perks and discover game-changing synergies to create the deadliest dungeon. With a multitude of minions, spells, buildings, ancient tomes, upgrades, and random events, every run offers new challenges and fresh strategies to master.
