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.
