i just had an amazing survivor pack idea like a special infected survivors

it's already on the site, thanks to Samm5506 and to K.Tastrophe for the port to L4D2

i mean that the surivirs would be smokers boomers withches and suck

There is, but I can´t find the link : /

from the link I gave you -
"This special infected mod pack has Bill over the Hunter, Louis over the Smoker, Francis over the Boomer, and Zoey over the Witch."

how is that different? or do you mean you want the l4d2 survivors? which would not work very well in game in my opinion.
