Pros:

+ maps flowed pretty good
+ most maps very detailed
+ enjoyed the challenge of many special infected
+ some cool ideas
+ I played through the whole thing lol
+ no nav problems the 2 times i ran through it

Cons:

- a few bugs nothing unplayable
- escape event after door opens in finale caused serious lag all the way till campaign ended
- map 4 was a little on the dull side
- map 5 had fun setup for finale and escape but dull up to it.

Conclusion:

overall better than alot of campaigns i have played thats for sure. If you take some of the good things that you did really well in this campaign and mix with new ideas for a second and even more improved campaign, i would imagine it would be even better. But all that aside good job for the most part and hope to see more.
