Portal Knights

Portal Knights is a cooperative 3D sandbox action RPG. In the world of Elysia, torn apart by the Fracture and terrorized by the Hollow King, you and your friends are its only hope, you must level up your character, craft epic weapons, and vanquish foes in real time.

You play as a Warrior, Mage, or Ranger, customizing your appearance, abilities, and gear, and unlocking new talents as you level up. Combat is real-time and tactical, weighing each foe's strengths and weaknesses, and you use mysterious portals to travel between dozens of randomly generated 3D worlds, collecting resources in caves, lakes, and dungeons.

You can build almost anything from dozens of materials and furnishings, unlock private islands for your own castle, and use Creative Mode to construct elaborate structures to share on the Steam Workshop. Four-player cooperative multiplayer or two-player split screen lets you build and explore together, vanquish dangerous Greatbeast bosses, and aid colorful characters with their quests.
