since there is a limit of 1000 characters in the comments i thought i'll just put my review here.

So, i played through this scenario with another friend and felt like writing a review. If you haven't played it yet, beware of spoilers.
For being the first (or one of the first missions you made) this is a pretty good one. the atmosphere, the use of music and audio clips (did you make some of them yourself?).
There are a few things i noticed that could be improved a bit:
-I was expecting more enemies (both zombies and rebels), it could be that we managed to walk past most of the encounters. I was expecting a couple of extra rebels in the optional camp. the amount of zombies at the lab and the Crow colony (?) was good. a couple of extra sentries near the airfield (in the towers for example) wouldn't hurt. And i was expecting a bigger finale after the cures were found, with the music (and the "4 minutes till extraction) I thought a big horde was coming and we were supposed to survive it.
-We had a small bug after saving and loading this mission that both our gasmasks were gone.
-The AT guy is carrying a single use rocketlauncher and carrying 3 extra rockets...

those were the "bad" things imho.
I'm looking forward to your other scenario's
