Pros:

- UT in L4D2!
- Kudos for the texturing work.
- Maps in minimal UT style

Cons:

- Had some trouble finding my way
- Not enough places to get decent cover at times
- Maps in minimal UT style
- Tends toward a one-play-only campaign

Conclusion:

I loved this campaign because I used to be a hardcore UT fan. This campaign brings up a ton of memories, but is also a reminder that old-school mapping takes away a large portion of replayability in L4D2. This one is fun to check out, but gets old pretty quick (kinda like me, I guess). 
Anyway, a big pile of cool karma is heading your way for bringing back some of ye olde times.
