CDO2:Dungeon Defense Android Game Description:
The player acts as a dungeon keeper. His main task is to fill the mazes with monsters and traps so that the brave heroes can't get to the treasure. More than 100 types of monsters, 40 types of mechanical and magical traps, and lots of relics and artifacts that act as enhancements are available.
Goblin looters should be used to replenish resources. It will take them some time to go to the city and back, so it's important to plan for defense costs. Each dungeon is a complex of 4 separate rooms. After the first playthrough, a hardcore mode and an endless sandbox with unlimited resources open up.
