Terraria series
Following the release of the Terraria 1.3 update, lead developer Redigit had moved on to working on another project, though developers Yoraiz0r and Skiphs were continuing to update Terraria. Redigit returned to work with the team to develop 1.3.5, heavily involved in 1.4.

Redigit stated that he plans to later release Terraria 2, a separate game from the canceled Terraria: Otherworld, although little information is known about the nature or content in the possible upcoming sequel.
