[Mad Melvin]

There is a secret room in max payne 1 in the level where you kill the finito brothers. I don´t remember exactly where in the level, but at some point there is a door opposite to a bathroom. the door is sealed shut, but there is a crack on the door. shoot it to pieces and go to the room behind the door. then go out the window and follow the ledge to another window. Behind that window is a secret room with a reference to Buffy the vampire slayer. Hope that made any sense.
