Pros:

Optional lighting was an interesting mechanic.
The swing bridge event was very cool.
Good spread on the ammo - I kept going from weapon to weapon throughout the campaign, ading variety.
The elevator and the train jump scares - I usually don't like things like that, but those were very well set up and fit in with the map.
The custom graffiti and adverts a plus.
The custom trains in general really added to the map.
The finale didn't feel to cramped or open, just right.
The escape vehicle being a train was cool. One dosen't see that often.

Cons:

None at all.

Conclusion:

I agree with the others. This is one of the best campaigns I've played in a long time. Good, well-laid-out, detailed maps; interesting mechanics; and an impressive finale. I recomend this map to everyone.

Pros:

Excellent atmosphere.
Nightime campaigns like Death Toll and especially Hard Rain felt much more like I thought they would first hearing about them.

Cons:

Some outside areas seemed too dark. I know it's supposed to be unlit and pitch black, but even if there's no moon and it's overcast, one can usually make out bare shapes at least.

Conclusion:

Despite the fact that some areas seemed too dark, I still love this mutation and I can put up with it for the areas that look perfect. This is easily the best mod I've installed, no question.

Pros:

-Desert-themed map.
-Reminds me of the later Resident Evil movies, very nice.
-Jake added some nice atmosphere in my opinion.
-Custom grafitti, objects, etc.
-Custom music bits.
-The Tank music. Sweet mother the Tank music.

Cons:

-The orange filter is a bit strong, makes things hard to see sometimes.
-Little bit too much static and such Jake's and the rescue's voices.

Conclusion:

Overall excellent map. Jake giving instructions and some slightly crazy ranting added a lot of atmosphere, and I think it to be a very nice idea. Easily one of my favorite maps.

Pros:

Nice design on the rifle. 
The fire sound is quite good in my opinion.
Replaces the default M-14 with a more modern-looking rifle.

Cons:

There's a very annoying sound about half a second after the fire sound. It's actually louder than the fire sound itself.

Conclusion:

All in all, I really like this mod. However, the noise after the fire sound is too annoying for me to use it.
