Payday: The Heist DLC map takes place in Left 4 Dead's No Mercy hospital

The Overkill Software/Valve Software crossover between Payday: The Heist and Left 4 Dead is a new downloadable content map for Payday which features a holdup in the same hospital featured in the No Mercy map in Left 4 Dead.

Many fans were hoping for a prequel, but Overkill shot down that notion days ago.

Check out the trailer for the new downloadable content map in the video below.
