Pros:

- Immersive and very detailed level design
- Balanced, but challenging gameplay
- Heaps of custom content (skins, music, events,...)
- Quite a long campaign

Cons:

- No major cons

Conclusion:

Awesome and fun campaign, I really enjoyed it, even when playing with bots. It is on par with Valve level design, even surpassing it at times. If you haven't played it yet, do it now, it's IMO one of the top 3 custom campaigns out there at the moment, maybe even the best...
