A trailer has been released for the game collaboration between developers Valve and Overkill. Payday: The Heist No Mercy is supposedly set before the events of Left 4 Dead and will help fans of the series understand how the whole zombie outbreak actually started. As you may have guessed from the title it is going to be based around No Mercy Hospital which can been seen in the Left 4 Dead Series. There hasn’t been much information given by either developers but judging by the trailer there is alot to expect.
