Pros:

- Great Detail
- Good computer performance
- Nice Mall!
- Smooth Difficulty curve
- Nice finale

Cons:

- Some sound/music doesn't work
- AI bots got stuck a couple times

Conclusion:

Really awesome. Just a few fixes need to be done to make it a perfect campaign. The mall was just amazing. It's much better than the mall in L4D2, it looks like the mall in the city I live in.
