As the Chief Dungeon Officer (CDO) in *CDO2: Dungeon Defense*, your primary mission is to keep your dungeon thriving against relentless waves of heroes. Command the formidable Demon King and strategically deploy over 90 unique monsters, each with distinct attributes based on their type, race, and role. To maximize your dungeon's defense, summon monsters that offer the best synergy, enhancing their collective strengths to outwit and overpower the intruders.

Strategic choices are crucial, with over 80 types of equipment available for individual monsters, more than 30 Totems to place in each room, and over 90 Relics that provide dungeon-wide effects. Select the most effective items to bolster your strategy and ensure your dungeon remains impenetrable.

Stay vigilant with over 100 random events, each bringing its own narrative twist. Anticipate upcoming events and devise the optimal strategy to turn these challenges into opportunities.

The fate of your dungeon can shift dramatically at any moment. Invest in long-term research to enhance your defenses, employ Goblin Bandits for resource pillaging when supplies run low, and have your Demon King consume monsters to boost his stats. Each decision you make will influence the outcome of your battles, so choose wisely!

Achieve lasting advantages through permanent secondary attributes, which can be earned progressively through gameplay. The more you accumulate, the stronger your dungeon becomes.

Push the boundaries of your strategy to survive for 50 years and clear the game. Then, take on the Challenge Mode for an even higher difficulty, where penalties stack up, testing your resilience and tactical prowess. Strive to exceed your limits in these extreme conditions!

Engage in the competitive mode, which spans over a year, pitting you against other players without a specific clear goal. Show off your strategic skills weekly, as rankings reset every Monday, offering new challenges and rewards under varying conditions.

*Note: For the best experience, it's recommended to play *CDO2: Dungeon Defense* on mobile devices, as it may not function optimally on PC app players.*
