Pros:

Creative rooms
Clever panic events
Several DIFFICULT sections

Cons:

More deadly traps
Less carrying gas cans around

Conclusion:

Excellent campaign.  Killer finale.  Spent more than 3 hours playing with several friends trying to finish the campaign.  The first level has a wicked ending, but the earlier parts need to make it impossible to carry the gas cans from the earlier sections.  Also, need to randomize the "tank pictures" so they aren't so obvious and thus easy to avoid.  Make people take a risk when they choose to check pictures for supplies.

Overall, I strongly recommend this map to anyone reading this review.  Can't wait to take a bite out of Alpha Test!
