Left 4 Dead

That bug can be avoided by bringing up the console via the squiggly key and enabling subtitles. This gives you messages like "tank growling" and "smoker coughing" even when they are far, far away. The music is too unreliable

If you have PC and you arent using the developers console, give it a shot. Theres ways to set up single player where you can practice as infected

I've got to say, favorite level and ambush as undead in the entire game is on mercy. It's right at the beginning of the roof top finale. The area that leads to the elevator(not the whole hall just the immediate area under it) if you get hunters to stand on either side, and a smoker on the other side of the elevator witha boomer in one of the rooms and pop out at the right time. Ohhh man, worlds fastest and most epic winz will be had.
