Legends of Descent is the number 1 action RPG for Windows Phone 7. It is a dungeon crawler style role playing game, where you, the stranded dwarf, must fight your way through endless dungeons, slaying monsters, reaping loot, and equiping yourself with the very best weapons and armors. With tons of items (some with magical properties) and visually engaging spells, Legends of Descent will keep you coming back for more.
