Pros:

- Great map design
- Areas make sense
- Great finale area
- Perfect length maps
- Good item placement
- "Wind" on end platform is fun and not overused. (keep it this way please :p)

Cons:

- Nav needs a little work, 2 tanks despawned on the same playthrough.
- Safe room in the elevator; It was bugged and it took us about 5 mins to get it to work. Someone pressed the button while only 2 of use were inside, which might of been the cause. We fixed it by pressing the outside button then running in. Not sure if its intended to be like that. 
- Did not come across T3 weapons.

Conclusion:

Great campaign. Perfect length and fun finale. Would recommend. 

Pros:

- Decent intro.
- Complete campaign.
- Custom VO work.
- The outside areas are decently made.

Cons:

- Weird lighting
- Large open rooms, making no sense.
- Strange, maze like level design making it hard to navigate and become accustomed too. 
- Could of used more detail in the indoor areas.
- No hints, whatsoever.
- Barely any supplies, especially at finale.

Conclusion:

This campaign is decent. Not something I'd play again, though. Mainly due many design flaws in the interior parts. They make no sense and are just plain square rooms. This was a major gripe. It didn't flow well and my team agreed it felt too "winding", almost as a filler, between the decent intro and the finale.

You do have some skills. I'd like to see you work more on those indoor areas, though. Possibly revamp them? (I know this may be daunting). 

One of the better campaigns, I'd like too see more from you.

Pros:

- Almost flawless level design
- Added danger of the ledges
- Did not encounter bugs. 
- No texture errors.
- Lighting is just right.

Cons:

- Too few CI (not sure if this was intended)

Conclusion:

I'd like too see this a part of a finale for a campaign. This is what Dead Air's should of been like for L4D1. Great work.
