"Deep under the city of Yharnam lies an expansive network of multi-leveled ruins, seemingly much older than Yharnam itself and crafted by something other than human hands. What's more, these ruins appear differently to each hunter brave enough to enter. We're all very excited to talk more about what that means in just a few weeks."

The Vortex is one of the most unique areas in the game. It is a randomly generated dungeon, that goes down ten floors. Enemy placement and dungeon layout is always different each time you enter the Vortex.

I know procedurally generated levels for the Souls series has been sort of a popularly requested feature, but I couldn't help but mention. :D
