Pros:

- Great Atmosphere
- Good Setting
- A really good soundtrack
- Good voices
- Map 2 and 3 are fun 
- A lot to explore

Cons:

- Quite a few FPS problems
- Feels a bit generic
- First Map is repetitive to the point of being boring
- Special Infected music just ends after a few seconds
- Repetitive, easy finale
- It ends before you even reach the truck

Conclusion:

Overall i can see that a lot of work and time was spent on this but it has quite a few flaws. The first level is a bit boring: go into a shop, trigger an alarm, get the fuse...repeat and repeat. 
The middle 2  were very good though, i liked the eerie atmosphere in the third level. Sadly that was also the level were i had the most FPS problems, i've never had that low FPS before in any L4d2 Campaign. 

The finale was a let down, repeat the same thing a couple of times, fight horde after horde with some tanks mixed in and it wasn't even challenging. Than it ends at the middle of the stairs with some lame panning over a room - while you hear the Bots still fighting. 

Pros:

- Great setting
- So much attention to detail
- Great Textures
- Great Sound effects
- So much to discover
- A lot of creative ideas like the cable car
- It's long but not too long

Cons:

- Stupid AI, has problems getting into the cable cars, the safe room (Map 2)
- The Cable Car/Generator in map 3 is a bit confusing at first.

Conclusion:

This a really awesome campaign, with a lot of creative ideas and i liked it a lot. 
If only the Bots were a bit better, it would be more fun in SP as i sometimes like to just walk around those beautiful levels while killing some zombies without the hassle of getting some friends ready to play. 
Also the ending to map 3 could've been better done. After the generators i thought i was supposed to go back to the Cable Car and continue onwards. Instead i had to look for a safe room. But that's only a minor complaint. 

Pros:

- Creepy
- Great Atmosphere
- Awesome Soundeffects and scary voices (why are children so scary? :D )
- Random creepy Ghosts and Faces
- Great Leveldesign
- Great Enviroments
- Can be quite Challenging
- Never gets boring

Cons:

- Bots are really stupid, especially in the Finale

Conclusion:

This Campaign is just so much fun. I've played it multiple times with various friends and everybody enjoyed it. Despite the stupid Bots it's also quite fun in SP but nothing tops the experience with friends (especially with those who are easily scared :D )

Pros:

- Really captures Minecraft in every way possible
- Fun Finale
- Awesome Level Design
- Extremely versatile in the design, textures and challenges
- Crafting!
- So much to discover, so many hidden items
- Ender Dragon Easter Egg

Cons:

- Snow in the first map is a bit extreme

Conclusion:

This made it easily into my Top 5 Fan-made campaigns of all time.
