Descent: Legends of the Dark – The Betrayer's War (also known as Descent Act II ) is an expansive, deeply cooperative dungeon crawler where every decision matters, driven by player choices and powered by an app that eliminates the need for a Game Master. The game’s immersive storyline is filled with unexpected twists and turns, designed to captivate players of all skill levels. Campaigns can be enjoyed solo or with up to four players, requiring teamwork and strategic cooperation to conquer the challenges ahead. The Betrayer's War builds upon the thrilling dungeon-crawling experience of its predecessor, introducing new villains, quests, and gameplay mechanics. Players return to the world of Terrinoth, where they must forge an unlikely alliance with their greatest foe, Waiqar the Betrayer, to battle the formidable armies of dragons and thwart the sinister plans of the Uthuk Y'llan. All six heroes from the original game make their return, each armed with a new hero card and an array of abilities to help them defend their legacy against the encroaching darkness and the fearsome Dragonlord Levirax.
