Who wants to know what’s in the mystery box for Inside?

Game developer Playdead, boutique media company iam8bit, and sex toy manufacturer RealDoll have teamed up to create a limited collector’s edition of Inside. The twist is that they’re not telling you what they’ve actually created. For $375, you’ll get the PlayStation 4 version of Inside and “several” other items, with at least one of them presumably being the mysterious thing from RealDoll.

If you’re wondering whether or not you can do with this what you’d normally do with a product from RealDoll, the creators are playing coy. They do note that the package “weighs a surprising amount” and based on the box image featuring silhouettes of the multi-limbed Huddle, we’ll leave the kink-shaming to others.
