After teasing a 3D sequel when Prison Architect received its final update last May, developers Double Eleven and publishers Paradox Interactive have announced that, yep, Prison Architect 2 is indeed a thing that is happening - and in 3D, no less. Prisons will now have multiple floors to police, as well as a whole new inmate behaviour system to navigate along the way that will feed into gang warfare, escapes and other budding management problems. It's coming out surprisingly soon, too, with its reveal trailer dating it for March 26th.
