Pros:

Creepy Atmosphere
Massive
Random radio spawn 
Supplies on specific points of the map

Cons:

Can't find one so far

Conclusion:

Love this map. The creepiness is enough to make me check if the bots are close by. The random radio spawns and scattered supplies keeps things fresh as you're not forced to hold out on one specific part of the map.

10/10 from me. I just can't find nor have i experienced anything really negative on this map. 

Pros:

Well placed supplies
Well thought out hold out points
Excellent map design
And stuff that the others have already mentioned

Cons:

Most of them are already stated by the others

Conclusion:

This is one of the best survival maps i have played. It has a lot of eye candy, with good gameplay to match. Although the hold out points are sort of easy to defend, being overrun is still a possibility if you get careless or get too occupied by a tank. And as Golden Android stated, the map does indeed encourage both styles of gameplay.

Hoping to see more survival maps of this quality from you. I've always preferred survival over campaign

Pros:

Good atmosphere
Realistic house design
Amazing implementation of weather

Cons:

None that i can think of

Conclusion:

I've always liked maps with rain on it, so this was an instant download. And hell it didn't disappoint. I love the design of the house. Its pretty realistic and hell it looks like a place i'd love to relax in. The rain and thunder going on is somewhat relaxing for me. Then again, i've always found rain to be relaxing.

I can honestly just waste time admiring the atmosphere of this map.

Awesome job on this one bud. Hope to see more survival maps from you.

Pros:

Great design (Loved the still playing Night of the living dead movie)
Caters to all types of players (except glitchers, thank god for that)
Plenty of camping spots
Huge amount of weapons
Jukebox 

Cons:

None that i can see

Conclusion:

One of the best survival map for me. Love the fact that the map allows for both camping and run and gun play style. Now if only i can find players who doesn't rely on glitches on survival maps.

Pros:

Good atmosphere
Unexpected scares

Cons:

No direction/hint as to where you need to go
Camouflaged ladders
2nd map is close to impossible (finished it on my 2nd try though)

Conclusion:

Its a well presented map. The map really gives off that creepy vibe. Didn't expect to get scared by a L4D map, as i've played a couple of supposedly scary maps and didn't get scared at all. Unlike others, for me the darkness is just alright. Serves a purpose of giving the ruins a haunted feeling. I got one instance where i jumped off of what i thought was the right way only to find my way back to where i came from. But that's a plus for me, actually. 

The map will also test your patience (luckily, i'm the patient type)as you will get lost, mainly because of the cleverly camouflaged ladders, and get attacked by an endless wave at one part of the map, which makes the already difficult job of finding the way out even more difficult. 

Despite the flaws, i give it an 80. Cause despite the almost obnoxious difficulty of the 2nd map, i did enjoy it. Just try to ease up on the challenges next time.

P.S. Don't even try to play this on the Last Man on Earth game mode. It ain't pretty. It might get easier as part of what makes this map harder is the endless horde. But it'll get extra scary. Especially if you play that game mode on this map on your first try.

Heed my warning, you might wet yourself.
