Pros:

1st map:
“Custom” speech. Nice
Explosive barrels
Panic event before the Safe room was pretty challenging
2nd map:
Crescendo was pretty good
Overall:
Having a custom campaign that fits between Valve campaigns

Cons:

2nd map:
Invisible wall was too “visible”, next to the truck
3rd map:
It was quite unclear how to get to the car at first,  so we all died	

Conclusion:

First, thanks for putting up another host to download.
The map is good, but a little bit short for my likings. Apart from the kinda confusing finale, the map is great.
