Okay, if you’re a L4D1 fan and you’ve held out this long on buying Left 4 Dead 2, let me clue you in on a little something:
In the first level of The Parish there is a jukebox. There are a bunch of different songs on it. (EDIT: most of the songs are from the fictional Midnight Riders band who are introduced in another L4D2 campaign.) One of the songs is “All We Want To Do Is Eat Your Brains”, but the really neat thing is that even if you’re playing in commentary mode where the Director won’t normally send waves of zombies at you, playing that song will trigger a wave.
Sing along, everyone!
