Conclusion:

 We be Jammin ya man. What can I say this is great, replaced nicks medkit real fast as soon as I seen this, tried it, works great.

Pros:

Its wrong in the sense its right

Cons:

after about 2-3 chapters in, its starts to become annying

Conclusion:

Good for a laugh once in a while, it will get on your nerves after a bit. I'm giving this a 7 due to it is funny, well made and original for the game. 

Pros:

Everything

Cons:

NONE

Conclusion:

Finally with this I have proof to show others that yes indeed, locked maps existed. Why they are not released with the game is just dumb

Pros:

Fun puzzles
Bots seem competent
aura of not sure whats going to happen next 
Like the whole gas can to get items

Cons:

Finale had to much to do, wasn't fun dying 4671 times

Conclusion:

Overall fun, not a good idea to do tired, thankfully the amount of zombies was just right. The finale IMO was just to much to do. that's really my only bad point that I have with the whole thing, other then that, the work is amazing, creepy cameras to keep a eye on you, and love the surprises behind some pictures lol. 

Pros:

Very Creepy
Loved it
Long

Cons:

Bot in finale feel down ladder alot, no big deal tho

Conclusion:

Loved it for as long as it is, wish valve made good campaigns

Pros:

No Kidding its Dark

Cons:

Some places maybe just a little to dark, but then again read the name its supposed to be.

Conclusion:

I would love to see a lot more campaigns made the same way, im impressed with the job you did.
