Pros:

- L4D1 Survivors
- Versatile environment
- No glitches or errors
- Feels nice and flowy and long enough
- Fun Crescendos
- Nice and open to explore
- Uncommon Infected

Cons:

- Could use some more supplies (Ammo, pills, throwables,...)
- Might I suggest putting the supplies in front of the last saferoom inside the actual saferoom? It looks weird all empty.
- The Finale should be larger and more open, it's kind of a bottle neck and dead end now, gets really tough.
- Also, Finale could use more supplies, like throwables, pills, adrenaline,...
- It doesn't really make sense that rescue is coming and the guy on the radio says that he's on his way when the boat's been there the whole time.

Conclusion:

A very fun campaign. I had fun exploring about a bit and taking different paths. Yes, the environment has been done before, but you manage to alter between city, apartments and others to make it feel flowy and fun to play. Lots of the Crescendos made me laugh, and I found them pretty well done. Just for fun you could make the survivors curse or swear when it happens, since it's sort of out of their control. Or just add some more Survivor dialogue as a whole, to make it all even more fun to replay. I had a hard time finding enough supplies, I did encounter the occasional molotov or FA kit, but only way into the second map. Nevertheless I pulled through quite alright, but it wouldn't hurt adding some more.

The biggest 'problem' is the Finale. Theres only an ammo dump, FA kits and some weapons. Perhaps try adding pills, bile, molotovs,... or perhaps I entirely missed them? The second thing is, it doesn't really make sense for someone over the radio to yell that he's coming when the boat's been there the whole time. It would make more sense to have a Scavenge finale, or just hide the boat until the time is right. :> Lastly, it's sort of a dead end for the Survivors, which can be a real pain on higher difficulties. There's only one direction from which the Infected can attack, but that also means it's a dead end for the Survivors, and the rescue vehicle happens to be a bit in between both camps. Try adding more pathways or making the finale area more open. To take other reviewer's critique into account, perhaps make the final map a tad shorter, because it is a long way back to the finale if you happen to die there.

All in all, I had lots of fun with this one. Don't let the cons wear you down, as most of them are nitpicking. The only thing I'd really suggest is changing the layout of the finale area. For the rest, a nice and flowy map with lots of fun events and exploration. Should you update the map and the finale I'll gladly test this again and alter my review. Thanks for sharing and good luck! :)
