Game description:
Legend of Grimrock 2 is a dungeon crawling role playing game with a modern execution but an oldschool heart. A group of four prisoners have shipwrecked on the secluded Isle of Nex. The island is filled with ancient crumbled ruins, mysterious shrines and a vast underground network of dungeons and mines. If the prisoners wish to make it out alive, they have to overcome the challenges devised by the ominous mastermind of the island.

Legendary!
