Pros:

Lots of zombies as advertised
Challenging
Very Fun
Stable (No Glitches)
Random panic events

Cons:

No creshendo events
Radio is difficult to find in finale (its directly in between the two trucks)
A few annoying invisible walls

Conclusion:

Would recommend to download.

Pros:

Challenging campaign
Beautiful Scenery
The Car ;)
The Finale - good challenge
The tank smashing through the flaming car creating a path
Stable

Cons:

one or two zombie spawns in a wall

Conclusion:

Very fun, should be considered for inclusion in the actual game. Its just like the valve campains, only better.

Good work :)

Pros:

Very good campaign, challenging.
Scare tactics when going through some doors, straight into a boomer or tank - awesome
Lots of zombies
Epic Finale

Cons:

Some texture issues (purple floors, missing walls)
Big red 'ERROR' messages occassionally (But still playable and compleatable)

Conclusion:

This was very fun, and baring the minor texture issues flawless. Prehaps it is somthing to do with my setup, but it is still playable and most importantly completable.

Very fun. (Would have scored 90 w/out texture issues.)
