Dungeons 3

This is the level complete trophy. One of the rare levels where you're expected to build up your dungeon and stay there. Apart from the odd Overworld incursion to take over Islands of Good, you need to stay in the dungeon and prepare for invasion after invasion, to knock out enough invading Heroes to feed to a sacrificial pit to summon the Ultimate Evil. The level ends and the trophy awarded once enough Heroes have been sacrificed.
