Application Description

As the Chief Dungeon Officer (CDO), your mission is to keep your dungeon thriving and resilient against the onslaught of heroes. Command the Demon King and strategically deploy over 90 different monsters, each with unique attributes based on their type, race, and role. Summon the right monsters to create the perfect synergy and maximize your defensive capabilities.

Make strategic choices with the variety of items at your disposal. Equip your monsters with over 80 kinds of equipment tailored to enhance their individual strengths. Place more than 30 types of Totems in your dungeon's rooms to bolster your defenses. Utilize over 90 kinds of Relics to grant powerful effects across your entire dungeon. Select the best items to align with your overarching strategy.

Be prepared for over 100 random events, each with its own narrative. Stay informed about upcoming events and devise the most effective strategies to navigate them successfully.

The fate of your dungeon can shift dramatically at any moment. Invest in long-term research to strengthen your defenses. Deploy Goblin Bandits for pillaging to supplement your resources. Have your Demon King consume monsters to boost his stats. Make critical decisions and witness their impact in battle.

Unlock permanent secondary attributes that provide substantial advantages as you level them up. Earn as many of these attributes as possible through gameplay to fortify your dungeon's resilience.

Push your limits and beyond! Aim to reach 50 years to clear the game, and then continue the challenge in Challenge Mode at an elevated difficulty level. As the difficulty ramps up, so do the penalties. Test your strategies under these extreme conditions.

Engage in the competitive mode that lasts longer than a year, pitting you against other users without a specific clear goal. Every Monday, rewards are distributed, and rankings are reset, offering a fresh start each week. Showcase your skills in varying conditions and rise to the top.

Note: For the best experience, it's recommended to play on mobile devices, as the game may not function optimally on PC app players.
