Nothing yet... though it sounds good :)

Getting a .txt conflict on parts 2, 3, and 4. Cannot play. Kicks from server back to main screen.

I'll Look into this as soon as I can. Weird issue.

Highway to Hell Brilliant, Gameplay Can't fault it, there is one minor problem at the end, when the stats come up showing

0 Hunters killed
0 Boomers killed
0 Common Infected killed

its like that all the way down even for the pipe bombs and molotovs cocktails
At the end it says
0 Zombies Were Harmed in The Making of This Film.

The Sky and the horizon have different textures and create a very noticable fault line. I can provide screen shots If you like. Also this doesn't need to be changed but I feel like the panic events are overdone.

Conflict with having more than one part checked at a time. Trying to figure it out :)

That's normal. More to do with the meta files contained therein. If they conflict with eachother it's a "good" thing.

At the beginning of the campaign,when walking out the door into the hall,someone'll say one of their "get-in-the-saferoom" lines. Are they supposed to or what? I'm guessing no, but I've been wrong before.

No, that's never happened in any of my iterations of this campaign.

How do i put Highway to hell through the dev console, like how Dead centre is put through
map c1m1_hotel.

just type in highway etc

Thanks for that it worked brilliant :)

Conflicts with 1,2,and 3 even with no other addons selected. loads like i'm joining a game then ejects me back to main menu.

i also had the no text info bug and i think i sorted it.
when i looked in add-ons it said i had parts 1-4 , when i browsed the workshop it also said i had parts 1-4 but when i searched through coimunity > colections and got on the main page it said i only had subscribed to the first part i subscribed to all and it now works ofcourse.

I try to join a game with my friends and it loads a bit then goes to a black screen
