Control: The Fundamentals expansion is now available on Xbox One
The Foundation sends players into the bowels of the Oldest House to discover its history. Jesse is warned by the mysterious Council that there is a problem in the foundations of the plant. A mysterious structure called "The Monolite" has been damaged and the Astral Plane is leaking into this foundation. If Jesse can't solve the situation, the Oldest House, along with the Bureau of Control, will be consumed by this contagious and invasive parallel dimension.
The announcement is accompanied by the DLC's launch trailer, which you'll find below.
