Just had a pretty lol moment in L4D2

We're playing Hard Rain, heading back with the gas through the neighborhood. I'm up on the roof (as Rochelle) and the other three are down in the street. A storm picks up, zombies start showing up and all I can hear is the wind whipping and the sound of gunfire.

Nick says something about zombies

Then I just hear coach, like he is trying to understand what nick said, yelling "Excuse me?! EXCUSE ME?!"
