Pros:

-Very creative, first map (i've seen) in a slaughterhouse.
-Each room is diverse, making it a fun-to-explore map
-Nowhere is safe forever, it forces you to move around and do different tactics.
-The map is believable, you could actually see it working and have people using it.
-(this is small, but it's still a pro) you can actually follow the path the meat takes, you didn't just have random tracks throughout.

Cons:

-The mist room. It's only one room, it would be cool to see the mist spill out into the hallway, or even as the time goes on to have it slowly fill the entire map to give it an eerie and creepy feel.
-It's a little small, adding outdoors area (like seeing where the meat goes out into trucks, e.t.c.) would be nice, and make it appeal to the audiences who prefer outdoors.

Conclusion:

Easily one of the best custom survival maps I've tried. The only cons are things that would make the map better as a whole, no bot glitches or bad nav meshes, no leaks. The design is well-thought out, it's fun to explore, it's fun to play in. Maybe consider the Con's for a second map, or something. All in all, excellent map.

Pros:

-Brilliantly textured
-Awesome Detail
-Different Areas, not everything looks the same
-Fun to play in
-The UFO is slippery (fun when dodging tanks :D)

Cons:

-Auto Horde Start (At least warn us before telling us it will start, like a flashing warning light, or a countdown screen, or something to let us know. And give us more time to prepare!)
-Little to no gas cans or propane tanks (in Survival Mode)
-Not that easy to traverse (No big landmarks or anything to help you out. It's a spaceship, you could have like an electronic map with a "you are here" thing in a few spots, just to help out)

Conclusion:

Really great map! Alot of work was put into this, I can tell. A few "eh's" here and there, like the gas can and propane tank shortage, and the automatic horde. But when you have things like the UFO to run around on and dodge tanks, it's hard to pay attention to those few misshapes. I HIGHLY suggest anyone who is a fan of Scavenge or Survival.

Pros:

-Creative
-Looks and feels like a train
-Fun to play through, and a challenge in the open spots with Chargers and Jockey's and what-not
-Good map to play with friends on
- Every so often props go by to make it more believable that the train is actually moving
-Finale seems simple to win at first, until a tank comes from behind and bashes you up & off the train

Cons:

-The trees sliding by looks choppy, try to smoothen up the animation to make it seem more like your moving along
-Anything that falls onto the "ground," falls through, yet you can still see the blue outline, and the outline moves with the train.
-Too little items in places, try to add a Magnum here and there, or some mollies and pipe bombs

Conclusion:

Really good map, creative, fun to play, unlike anything i've seen. The tree's moving animation was a little choppy, try to smooth it up a little to make it more believable. Item placing was a bit scarce in places, and the thing with the items falling through the ground, takes some points off, but the overall challenge made this an excellent map. I recommend you download and play this map, I know I will a few more times.

Pros:

-Creative
-Cool fire effects
-Good voice acting
-Good Bot que's with the talking at the beggining.
-Nice custom tank texture
-Good detail

Cons:

-No common-uncommon infected
-No set location (where the heck are you? You start off on a helipad in the middle of a foggy place, and the indoors area gives no clues as to what it is. Is it a mall in the middle of nowhere? A secret army base that was abandoned? Where are you?)
-No reason the fire started (Are you telling me a fire started for no reason in the middle of a FROZEN place?)
-Why did you go back if you had no gas? Is just to be assumed the survivors had gas with them? If so, give a hint as in bot speech that its implied they have the gas.

Conclusion:

Not a very good campaign at all. In fact, actually one of the worst i've played for the reasons in the cons. Its not very realistic, and you have no idea where you are or what that building is doing there, or even what purpose it serves. Now, the voice acting and texturing and detail are really good, just use those skills on a new map.

Pros:

-Tons of nooks and crannies to explore
-Lots of items in places
-Good curving, looks smooth and flawless
-Realistic Lighting
-Good prop placement
-VERY good detail

Cons:

-The grassy areas up top look a little unrealistic, the height difference makes them look triangular and pointed. Try smoothing it out a little.
-The area past the pool look completely unrealistic and just  thrown together. Its a huge "lake" with mountains around, but empty nothingness beyond! Add more mountains and improve water, or just find another way to end the map there.
-Map looks like it ends up top, doesn't look like it goes on. Try adding some tops of buildings past the ones you see, or make a forest or something, just to keep it realistic.
-A little small, but just barely enough to be a Con.

Conclusion:

Re-do the maps edges at the top & bottom, smoothen up the grassy areas, and maybe add another explorable place. Overall, this is a well put-together map, and the only reason its an 80 is because its few flaws are kind of major, and can ruin the experience. But other than that, the detail, prop placement, and item placement are superb! So, just spruce it up a bit, edit some bits here and there, and viola! You've got a perfect Survival map! (Scavenge in a bigger resort wouldn't hurt either, just a thought ;) )

Pros:

Good designing

Realistic lighting

Water looks like it goes on forever, no abrubt ends

VERY difficult

Cons:

Where is the shark you display? Couldn't find it

A few spots where you look below the water and see a wall

Not much difference in scenery

Conclusion:

It a good map, as long as you don't mind a challenge and not many scenery changes. No sharks, as the picture entails, makes it kind of a bummer, but you can't really pay attention to it with the huge mob of zombies. All in all, pretty good map, and worth downloading.

Pros:

-Good detail, in every area
-Plenty of spots to hold out, and none of them completely safe
-Made the spots for zombies to come in realistic (i.e. the ceiling instead of halfway up the wall)
-Creative way to call the horde, and cool animation + voice acting to go with it (no spoilers here)
-Plenty of realistic lighting and such
-Awesome custom textures for the movie posters

Cons:

-A few places that survivors would like to hold out or explore, but can't (the office thing with the movie camera leaps to mind)
-Kind of unrealistic with the flooded part, I know its cool and all, but there's no real way the water could've gotten in there. (This is kind of a pro and con)

Conclusion:

A must-have for a Survival player. I'm not a big fan of survival, but i'm planning to play this map more than once. Amazing care and detail, along with some cool effects to go with it all. No noticeable nav errors, which is good as they can sometimes ruin the experience. A little bit of unrealism, with the water, and some places that we would like to have held out it, but for the most part a really well done map. This map deserves its 95.
