Sunderfolk

Sunderfolk™ is a new turn-based tactical RPG adventure where you use your mobile device as your controller*. Inspired by gathering around a tabletop RPG table with friends, it is built with the couch co-op experience in mind. Up to four players can play together as you adventure through the magical and dangerous Sunderlands.
*The free mobile app is required to play the game.

Each player will pick one of the six classes (Arcanist, Bard, Berserker, Pyromancer, Ranger, and Rogue), and together, you'll venture out into the Sunderlands and engage in turn-based tactical combat. During combat, there is no set player turn order, so your strategy can adapt in a moment's notice to react to the conditions of the battlefield. With new enemies appearing at every turn, it's up to your party to find the best approach to each mission.

Between missions, players will return to Arden and help improve the village. You'll unlock and upgrade different local vendors, build relationships with other Sunderfolk to earn rewards, and outfit your characters with new Skills, Weapons, Trinkets, and more.

Your goal, as the heroes of Arden, is to protect the town and its Brightshard from the corruption of shadowstone and defeat the threats from the surrounding Sunderlands.
