Co-op action RPG Dauntless, the Monster Hunter-style game about tracking and battling deadly Behemoths across an aether-charged wilderness, is now in open beta.   

In Dauntless, players become Slayers, who work together to fight gigantic monsters that are consuming the very essence of the Shattered Isles, the broken, floating realm in which the game takes place. It features a single-player campaign and an "Evergame" mode that extends beyond the story with ongoing challenges and rewards like "Heroic" difficulties and Dire Behemoths, and developer Phoenix Labs said it "will be continually adding content and updates to Dauntless," including new expansions, adventures, and Behemoths.
