Pros:

- the game didn't crash for me :)
- functional AI navigation with no problem except the final escape
- a variety of environments, and i enjoyed playing on the rooftops
- solid gameplay with no noticeable bugs

Cons:

- as others noted, the rescue vehicle did not move during escape
- the water area and the rescue vehicle were a bit glitchy, easy to get trapped
- afraid to say that the map design doesn't feel very original, like a mix of valve campaigns

Conclusion:

It was a smooth playthrough, but I must admit that I did get bored on a couple of occasions. The maps are well designed but do feel generic. I am glad the finale didn't crash as others noted!
