Re-Logic and Engine Software announced a new entry in the Terraria franchise today. It's called Terraria: Otherworld and is coming to both the PC and Mac.

Expanding upon the immensely popular action-sandbox title Terraria, exploring what might have been, and approaching gameplay in a new direction; Terraria: Otherworld represents a novel take on the Terraria experience.

Set in an alternate dimension within the Terraria universe, Terraria: Otherworld places the player in a life-and-death struggle to restore a once-pristine world – now overrun by a malevolent force that has corrupted nature itself – to its original splendor.

Combining elements of sandbox gameplay with role-playing and strategy elements, Terraria: Otherworld explores the Terraria experience in an innovative and unique way - providing a fresh approach to the “open world” genre.
