Pros:

- scavenge final changes from the monotonous "normal" finals
- tower explosion and bascule bridge makes the campaign more diversified
- very fluent campaign (I had never to ask myself "what the  f*** is this doing here ?")
- realistic in the sense that there seem to be multiple ways
- city background is really well-made
- I like big city campaigns :)

Cons:

- I lost my way one or two times (there should be more signs on the ground to show the right way)
- I haven't seen 1 smoker in the entire campaign, but I don't think it has something to do with the campaign itself (must be coincidence)

Conclusion:

Very realistic campaign with entertaining "varieties"
Pros outnumber by far the cons and I think this campaign has (almost) the level of an official Valve campaign
