Pros:

-Beautiful atmosphere and environment, makes you feel like you are actually in these levels

-Interesting variation of levels

-Variations of travel

-Well made details

-Locations are attractive and have much variety, from the streets of a busy city, to dojos and temples, forests, and many other places that would not be usually featured in a custom map

-Not too much weapons, unlike other custom maps. (A bit too many throwables though)

Cons:

=Bots got stuck a few times

=Too many throwables

=Would be perfect if a small swamp/flooded place was included, as there is fierce rain going on

Conclusion:

Overall, this is a great map, I would heavily recommend getting it, EXTREMELY unique locations and gameplay, making this a fun and active map, unlike other custom maps where gameplay seems to be like an utter bore.

Pros:

-Extremely Well-Made

-Nice level design

-OPTIONAL PATHWAYS!

-Attractive atmosphere

-Memorable

-Will be interesting to play in Co-Operative, and the many other gamemodes provided

-Finale also kind of has optional pathways, fighting up on the roofs will make you more vulnerable to tanks, fighting down on the ground will make you more vulnerable to infected

-Extremely large areas, making great for comfortable combat

-The partial verticality of the ship makes for an interesting fighting experience

Cons:

-Ammo seems too abundant 

-Little weapon variation 

-Ragdolls despawn on ship, partially subtracting from the great and memorable experience the campaign imparts to the player 

Conclusion:

Overall, this is an extremely great map, making perfect for almost any player. This campaign has very interesting levels, with good variety and intense gameplay through them. 

Pros:

-Great map

-Fun to play

-The ability to actually construct things, and upgrade as you go on

-Interesting design and variation of infected strikes

Cons:

-Could be a little harder, possibly like a horde  every time you add a part

-Bots cannot acquire weapons or objects directly from the upgrade tree, making bots weak and merely useless

-Bots WON'T GO INTO THE ROCKET!!!

Conclusion:

Great map, nice design and ideas, but playing with bots feels more like a burden to constantly heal them, and try to drop weapons for them. 

Pros:

-Great map

-Lots of variation in the environment

-Allows the players to switch weapons, and not constantly stick to one throughout the entire campaign

-Lots of intense action

-Interesting backround action

-Includes Easter Egg

Cons:

-The one problem I had with this map is that it was constantly crashing. It keeps showing me something of a precache error. 

Conclusion:

Overall, this is an extremely great map. One of the best custom maps out there, and it sometimes feels better than official Valve maps.
