Pros:

Well designed campaign. I could see where you used suggestions from other reviews.

Play from map to map was very smooth throughout the campaign.

Loved the use of multiple special infected.

Special weapons were well placed and not difficult to find.  There was also plenty of supplies.

Cons:

Supplies were probably a little too plentiful.

No Melee weapons.

Conclusion:

Great short campaign, it probably could have used another map or two to make it a little more challenging.  It was well thought out, well designed, and I know that I will play it more than once.
