Dungeon crawl through the sewers-LEGO style.
Game description from the publisher:
Since the dark forces settled upon the land, farmers have struggled to maintain their livelihood. Monsters constantly ravage the fields and destroy most of the crops, and what is left is barely enough for families to survive. There is no longer enough to trade, and even if there was, the Goblin General's siege on Draida Bay makes it impossible to sell or buy anything. Prospects are grim.
In Heroica: Ilrion, it's up to you to locate the Catacombs, fight your way past vicious bats and lumbering zombies, and defeat the Vampire Lord to rescue the King!
