It may not be a zombie-filled hospital, but Payday: The Heist's "Wolfpack" DLC does include new weapons, missions, and what appears to be some kind of fog-spewing basement or stairwell.

You also get two new heists, a new crew member called "The Technician," a raised level cap and a few extra weapons when the DLC launches in North America, on August 7 for $9.99. If you're more into robbing French banks than American ones, the content pack has already been released in Europe for £6.49/€7.99.
