From Wikipedia:
Darkest Dungeon is a roguelike role-playing video game developed and published by Red Hook Studios.
Darkest Dungeon has the player manage a roster of heroes to explore dungeons below a gothic mansion the player has inherited. Played out in a mix of real-time movement and turn-based combat, a core feature of Darkest Dungeon is the stress level of each hero that increases with further exploration and combat; a character sustaining a high-stress level may gain afflictions that will hamper, or possibly enhance, their performance as an explorer. The Stress Symbol, or Iron Crown, a crescent with five inward-facing spikes, is also in the game's logo.
