Pros:

- Solid well-designed maps with little or no glitches
- Multiple paths made the world feel realistic and broad
- Perfect length and difficulty
- Awesome creepy nautical theme
- Beautiful finale (great music choice, too)

Cons:

- No additional dialogue

Conclusion:

This is arguably the best add-on campaign I've ever played.  Awesome job.

Pros:

- Visually beautiful
- Interesting, organic-feeling maps
- Great use of dialogue
- Fitting custom skins that require no additional mods
- Overall unique campaign that still feels professionally made
- Thanks for the never-ending M60's ;)

Cons:

- First map looked extremely low-quality (corrected at second map, so that may have been a graphics card bug on my end)
- Very short compared to most campaigns
- Bots take a long time to get on the rescue chopper

Conclusion:

All-in-all, a very solid campaign I'll be sure to share with friends.  However, I'd love to see it expanded upon, even doubling the overall length.
