Pros:

Long detailed maps
Creative and clever pathing
More than two hours of play time
Starts where Vienna Calling 1 ends
Custom models that I normally pass around in RL ;)

Cons:

I can confirm the invisible objects in map 5 reported by Cookies (beta so expected)

The helecopter sound played through out map 1 for me but none of my teamates had the issue so idk, could have just been my over-fracked system.

Conclusion:

If you are new to Vienna Calling, start with Vienna Calling 1 and then boot this one up and you'll be in for a long night of L4D2 goodness.  Thanks 44V!

Pros:

Excellent use of HDR lighting
Fun panic events
Lots of detail
Good China feel
Cool train event

Cons:

Slightly easy for my playstyle
Finale was a little uninspired but everything was placed well and it worked well.

Conclusion:

Highly enjoyable campaign.  The maps ran smoothly with good FPS and I had a bug free playthrough.  Some panic events were especially fun and frantic in thier cramped environments. Well done!

Pros:

Great environments with a snowy feel
Excellent lighting
Original finale that worked very well
Great looking/sounding custom content

Cons:

Was a tad too easy for my playstyle.

Conclusion:

Excellent work as always from CastorJudo.  I very much enjoyed it.  Looking out the windows on the plane to see the clouds rushing by was awesome.  Awesome job on the original finale too, the ice looked great as it broke away.  Very much worth the download. I had no problems/crashes during my playthrough.

Pros:

Well done custom content
Finale was super fun
Just the right amount of HP for me
Nice variation between wide and closed areas
Good FPS and was problem free

Cons:

Some areas look unfinished
Buddha looked a bit bright to me 

Conclusion:

Really enjoyed the campaign.  It looks good and plays well.  It was fun, and that is always most important in my book. The winding and narrow wall for the finale was well thought out and especially frantic. My team of bruised and battered strangers limped to the chopper rescue - perfect.  The score so far for this map is way too low for the quality of this work.  I hope raters will help it to improve.
