Pros:

space!!!!!
space mechanics

Cons:

the last level is the only one that seems to be fun for me
 boring
hard to find paths
bland space textures
When you are in space you can jump over all the zombies without taking damage
space textures look likes a bunker

Conclusion:

I LOVE space but I thought this campaign would take place 100% in space (that would make it and auto 8)
needs some improvement but defiantly can be a good mak

Pros:

silent hill
detail
funny ( seems more funny than scary)

Cons:

symbols are to hard to find (-.5)
boring without friends (-.2)
tanks are easy to kill(-.1)
witches can be killed with out taking damage (-.1)
to little infected(-.5)
almost no hoards(-.3)
map is dull(-.5)
to small of a map to have 1 entire campaign based of it(-.5)
way to much supplies to infected ratios (most damage I took was fall damage (-.1)

Conclusion:

don't get me wrong if you have friends or even are a fan of silent hill download this map. This map could be so much more please keep working on this

Pros:

great detail
nearly PERFECT levels
custom meshes
nice amount of witches
nice amount of tanks
Amazing atmosphere
great amount of supplies
uncommon infected
3 types of uncommon infected
all types of special infected 
great amount of weapons
Big map
fun to explore
realistic city
witch placement (you need to fight the witches you can't just go around them)
melee weapons
m-60

Cons:

and not a single con was given that game

Conclusion:

This IS THE BEST campaign I have ever played! ( I have played l4d 1 and l4d 2 ) and nothing comes close to the fun I had playing your map! Please please get a job a valve to make custom content you would be awesome. At lest keep making these campaigns

Pros:

a lot of special infected
a lot of common zombies
when you know what you are doing it is amazingly fun
first level has great mapping
throws you into the action
a lot of hoards
a lot of tanks
a lot of witches
good decoration
Love the map of the finale
Original
funny tank action on the finale

Cons:

level 4 too hard to navigate to the end
finale is to long/ seems like it does not end
Witches are easy to avoid
little variate of weapons
to short
so areas seem just pointlessness
little variate of speacial infected. ( mostly spitters,hunters,and boomers)
the color can get boring
Tanks in finale keep committing suicide(But it is very funny)
There is a spot where almost no infected can see you in the finale 

Conclusion:

This map has nice penitential but it still needs a lot of work to become amazing. It is worth a try
