The developer behind Broken Age, Massive Chalice, The Cave, Brutal Legend, and of course Double Fine Happy Action Theater is developing content for the PlayStation 4 tech demo known as The Playroom.

The Playroom is the augmented reality and mini game application that Sony's been using to show off the ways the DualShock 4 controller can interact with the PlayStation Camera. Sony Vice President of Publisher & Developer Relations Adam Boyes announced Double Fine's involvement at PAX this weekend during Sony's PlayStation Indie Arcade event. Like The Playroom itself, Double Fine's DLC will be free to all PS4 owners.

Double Fine's experience developing Happy Action Theater, a suite of augmented reality games and activities for Xbox 360 and Kinect, makes it the perfect choice to help out on The Playroom. Some sites are reporting that the studio's development on The Playroom goes past mere extra content, but Kotaku can confirm that the original announcement did indeed concern only DLC.
