LEGO Hidden Side Sets

Hidden Side invites you to join a fearless team of ghost hunters, who dare see the unseen and help turn a haunted world back to normal, one ghost at a time. This theme includes a series of “haunted” building sets full of awesome functionality and secret surprises. Activating the free augmented reality app brings the models to life, revealing a hidden world of interactive mysteries and challenges to solve. When combined, the two worlds make each other even more compelling and fun. The app also consists of a digital game that you can play independent of the building set.
