A mystery collector's edition of Inside was recently announced by the game's developer, Playdead, and is set to feature an iam8bit and RealDoll collaboration. The contents of the iam8bit x Playdead x Real Doll collaboration box have been fairly secretive, but the collector's edition of Inside will contain a Playstation 4 game disc for inside and Steam keys for both Inside and Limbo. The box will also contain "other stuff" though all companies have not spoke out to what these things are.
The partnership for the collector's edition of Inside is perhaps one of the strangest in gaming history, because of the inclusion of a RealDoll collaboration. RealDoll is currently the leading manufacturer of adult intimacy dolls. Inside on the other hand lacks any suggestive content and instead focuses on existential anxieties. The special edition currently has no expected shipping date, but Playdead has stated it will ship "when it's done."
