MISTROGUE: Mist and the Living Dungeons is a Realtime-Dungeon-Generating Action Rogue-like game developed by Polyscape. The game is set in a labyrinth left behind by a kingdom that is said to have reached its peak of prosperity a long time ago. The dungeon is filled with life and has its own will due to the forbidden magic that constantly changes its shape. The game follows Mist, one of the treasure hunters living in Lootgar, who sets out to explore the Living Dungeons in search of the whereabouts of his missing father.

The game features living dungeons that dynamically change in front of your eyes, making the gameplay unpredictable and challenging. The structure of the dungeon changes constantly, and Mist's level resets every time he enters the dungeon. Players can use items and change their equipment in the middle of a battle, and effectively mix and match inherent skills to increase the synergy between skills multiple times. The game also allows players to use the unique puzzle aspects to clear the maze and create retreat paths using the item 'Maze Stone' or special skills from certain equipment.
