Beast: Ashfall

From BoardGameGeek:

Beast: Ashfall is the third and final expansion to Beast, the asymmetric hidden-movement game in which one player controls a primeval Beast while the others cooperate as Hunters tracking it down. The Northern Expanse has fallen into ruin. Skies fill with smoke, the land turns to ash, and new Beasts have awoken in the wild. Ashfall focuses on bringing new life to the original game's map. Hidden paths and boats open new ways to move and pursue, reshaping how Hunters and Beast use the Northern Expanse. The expansion adds three new Beasts and three new Hunters, each with their own asymmetric abilities. -description from the publisher
