Dungeon Overlord is a card-based tower defense game. In the game, you will be in charge of building a defense in a dungeon. The monsters that come out of the dungeon are divided into waves. Your goal is to protect the resources and get stronger by upgrading the tower. You can choose a card from three types: weapon, armor, and health.

When you play the game, you will be in control of the monster. You will have to decide which way to attack the wave of enemies. You will also have to consider the ability of your tower and your current strategy.
