Pros:

Everything!
5 maps!
Awsome effects!
Plays on my 1 core!
custom music!
Not a port!

Cons:

None!

Conclusion:

This really does feel like the best campaign,it really does.Download,have your friends download and everybody play!I don't want to spoil any details just try and see how awsome it is yourself.

Pros:

The most fun I've had with survival.
Good difficulty.
Many different functional activities.
Amusing.
Chopper ride!
Skateboard ride!
Drum set is functional!
Tons of items.
A few secrets.
Lots of stuff to climb on and navigate.
Functional mounted machine guns.

Cons:

Hardly any melee weapons.
Unwanted disco lighting when shader is set to high or very high(medium shader was ok).
Bots always fall off of nearly everything.
Some textures look low quality.

Conclusion:

 Like I said the most fun I've had with survival.I played this over and over with another player (guy I didn't even know)for about two hours.People kept joining and leaving because it was too hard,but we stuck it out and almost got gold but we accidently burned our selves with the 20 + gas cans we stored,lol.Could've got gold if we didn't have to baby sit two bots(they kept falling and incapping themselves).I'm not going to spoil anything but there's alot of activities to do on this map so download now.Don't forget to read the manual.And set shader to medium.

Pros:

Very long,epic levels.
Very realistic eviroment.
Lots of fun to play with friends or bots.
L4D2 in the upstairs bedroom with custom music.
Large amounts of depth in the levels.
Enough weapons and items.
M60!
Storm during the finale.
survivors speak.
Parking garage is epic.

Cons:

Poor performance during the first minute or two of the second level.

Conclusion:

This campaign is going to get replayed by me and my friends alot.This is a nice long campaign that actually requires free time set aside to finish.So,download now,gather your friends,lock n  load and get ready 'cause it's gonna be a long one!I can't thank the authors enough.Extremely good job here.

Pros:

Long.
Great scenery.
Loaded with nice textures.
Climatic events have mounted machine guns and goodies.
Fun to explore and play with friends.
Good performance and frame rate.
cool loading poster.
Tour of Terror is a good name.
Five quality maps.

Cons:

Sometimes the bots take a break when you're pounced.

Conclusion:

Totally awsome scenery and architecture are packed into this campaign.For some reason the bots decided to take a break and just stand right next to me when I was pounced,but it only happened once.I played this on two different machines(both of them pretty much antiques) and experienced no glitches,errors,or crashes.Everyone download this and try.It's labled beta,but plays like complete.
