Pros:

- Great lighting
- Good game-flow and nice detail
- Well designed designed and creepy
- Some custom models

Cons:

- Programmer intentionally uses Valve's bad surviver AI against you
- Unfinished textures in the room while waiting for the train, and the train textures look bad

Conclusion:

To be honest, this is in the top five best maps. This is more than a map, it is art. I love the lighting. If if was not for incomplete textures and using AI against the single player, the rating would be a little  higher.

Pros:

- Great custom music
- Sets good atmosphere 
- Creative and different from traditional maps

Cons:

- It is nothing more than an obstacle course
- More luck than skill required since a smoker can pull off anytime and you will need to start from the beginning
- No re-playability 
- Lack details that some of the other maps have
- some graphical glitches

Conclusion:

Good to try out and play if you like jumping games. This is not a map you will be playing over and over.
