there was just a new update for 'Dead Air' added today on L4D2 and once you get to the 2nd level, your teammates do not shoot at normal infected at all(only special infected) until after you get passed the part where you have to lower the garbage can...

i literally just stood there and watched as a single infected killed off each of my teammates without any of them shooting or even trying to shove the infected away.


i took screenshots but too lazy right now to upload them.

thanks!
