Well, we're not going to reveal everything just yet but there is a Prison. The prison will however house the torture equipment (another great boon of being able to build objects instead of having to dedicate whole rooms to one function). None of the rooms we have currently stray very far from what DK had, so no whole unique rooms with outlandish uses, however as i've mentioned, objects are a thing. There will be certain objects that have more... unorthadox uses, but those will usually have to be unlocked by recovering their schematics in the world.
