Pros:

Amazingly detailed maps
Really cool custom props
Nice flow from map to map
Lots of fun exploring
Fireworks were very cool!

Cons:

The post-processing effects were a little overdone in places
You can get lost but this made it more realistic
Would be great in L4D1

Conclusion:

One of the best maps I've ever played in any game.  It's like playing a brand new version of Left 4 Dead.  Definitely rivals a Valve map.  And, it's lots of fun!

Pros:

Lighting very good
Finale environment was cool
Perfect campaign length
Very good atmosphere / design

Cons:

Lagged quite a bit on my system (Core 2  Vista 4 gigs ram, Nvidia 9800 GTX+) especially on the first level
Some rooms seemed unnatural to the area

Conclusion:

Overall, very enjoyable.  Enjoyed the different music and sounds, cool lighting, I always felt like I knew where to go, very cool boat house at the end.  I played single player on Normal Difficulty.  Quite challenging. Will definitely play again.

Pros:

Good brush work
L4D1!  Thanks man!
Lighting was very good
Good flow / gameplay
Loved the moving wallway
Great texturing

Cons:

Some of the areas have been done to death in other maps

Conclusion:

Overall, very enjoyable campaign.  It was the right legnth, the right supplies balance, and challenging enough for me ion single player.  I will definitely play it again!

Pros:

Appreciate the L4D1 support!
The up/down/around flow was good
On single player I found it challenging on Normal
Supplies seemed well balanced
5 maps!

Cons:

Not as picky as others, I found the cons to be minor
Some areas had overlapping brushwork
Some areas felt like Valve maps
I would've chosen different Detail sprites
Never saw rescue vehicle but we all made it

Conclusion:

Overall, I liked it. I was challenged, I felt like I wanted to explore. It could use another pass on bug fixing, but I'll definitely play it again. Stairs without handrails don't seem normal.  Overall, I enjoyed it. Great job author!

Pros:

Awesome detail, skybox is incredible, not many camp points

Cons:

I liked it a lot. I can't think of any criticism.  Would be a great campaign.

Conclusion:

The skybox technique is worthy of decompiling to learn something new.  Very nice job. Lots of fun.
