Double Fine's highly anticipated platformer Psychonauts 2 has been delayed. The game was originally slated to release sometime in 2018, but the developer has now confirmed that the title won't ship until at least 2019.

Double Fine broke the news today in an update on Psychonauts 2's Fig page. In the update, Double Fine revealed that production on the title is progressing and "five full level teams" are now at work on it. However, now that development has ramped up, Double Fine has realized that the project will take more time than it initially estimated.
