Favourite survivor is bill, mainly because i started off using francis, but i didn't win a campaign until i started using bill. the old sod's a good luck charm
favourite infected is a tie between smoker and hunter, i just couldn't decide. it's just so darn satisfying when playing the last campaign, and after the barn, as everyone jumps down to the rail tracks, you come up behind and drag francis to a grim demise, alone and cut off from all help, as everyone else is already by the depot, and all they can do is listen to his cries for help slowly die away...
but just as satisfying is jumping the last survivor JUST before they make it to the safehouse, ripping into their flesh as a solid wall of zombies falls upon the prey, leaving nothing...
i got a bit carried away there :3
