Pros:

5 Maps
At least the maps are easy
Interesting areas
Light hordes

Cons:

Bots are really dumb. 
Not enough hordes
Not enough supplies 
Maps doesn't look that interested. 
Did i mention that the bots are dumb?

Conclusion:

Where is all the supplies with all those rooms and doors?
I had to kill the bots in the first map because they were scared to enter the safe room LMFAO
They wanted to stay outside the safe room haahahahah
Also i don't have a issue with the hordes really, but when it says get ready for a fight and you only see about 20 zombies, sorry but that is a issue. 
overall not bad, but not great. Its ok for a fun map to go though. :)

Pros:

Epic Maps
Great looking visuals
And sound effects
Nice atmosphere
Nice visual effects
There is really a tornado in the game , just wait until you see it. 
Bots seems to function ok at various times
You get to ride on a Boat :)  

Cons:

Bots could function better
Little confused on where to go in the Second map
I want more maps :( 

Conclusion:

Alright this game was crashing before, but i found a way around it, i think and it seem to work. Download Belle FireL4D2 and the other belle fire = Belle Fire. Just click on the authors name which is FOUND and download both Belle Fire's. In the first map you will see something lighting up, like a box or something, don't hit it. Keep going until you have went to every spot on that map until you cant go any further, than go back to that box and hurry back to ladder to get to the other side. Also i think the game crashes if the frame rate hits  a certain number. There are frame rate issues, so i tend to not look the direction where the frame rate goes down the most. Its tricky, but its works. Once you play it, you will understand.

Anyways, this is a awesome map, a boat ride, a tornado, tanks are fun to fight due to the areas you be in. Just a great fun map, download and play it with me :) I do wish the maker will clean up the maps and fix the errors and make more.   

Pros:

Cool visuals
Great Music
Love the subway going by
Nice selection of goodies, just like the movies
I love how some of the l4d 1 players show up to help :)

Cons:

Slow motion only seems to happen when the subway comes by, that is not very often.

Conclusion:

I love it. I would like to see more slow motion added often, not as much, but a little bit more than what it is now.
Thanks :)

Pros:

Awesome visuals
Nice effects
6 Maps

Cons:

INVISIBLE TANKS
Not enough kits, or ammo or pretty much anything in the finale.
Invisible Tanks <-----------------

Conclusion:

I would like to see a Part 2
Please fix the invisible tanks
