Pros:

-It's Helms Deep!
-Nice Music
-Clean Textures
-Cool Events
-Sufficient supplies
-Ending

Cons:

-Difficult(I completed this map through a dedicated server)
-Not enough time to set up
-Infected climbs invisible walls

Conclusion:

Very good map that's worth downloading. This made me want to watch the movie all over again! The screenshots made me add this map to my watchlist.

Pros:

-Surf!

Cons:

-Not enough tracks

Conclusion:

I'm glad to see surf maps be ported into L4D2, disappointed that there isn't so much variety in surf tracks. Pretty good map, I hope you make more tracks.

Pros:

-It's Metal Gear Solid!
-Nice design.

Cons:

-Special Infected can activate hordes by surveillance cameras.
-There should be more instructions
-Bot navs are flawed

Conclusion:

It's a good campaign and all, but its difficult to pass the maps without clear instructions. It took me awhile to find out that you can destroy the electric generator by shooting through the glass at the propane tank next to it.
