hi all. at this stage, i've been testing this campaign privately in versus mode for about two and a half months. we generally play two games a night, and i'm happy to say that the gameplay is pretty much where i want it to be for a public beta release. so, as soon as i can get some technicalities addressed, i'll have a vpk for download. looking forward to sharing this with the l4d community.
i'll be adding more content to this page very soon.
cheers.
