Pros:

1st map:
“Custom” speech. Nice
Explosive barrels
Panic event before the Safe room was pretty challenging
2nd map:
Crescendo was pretty good
Overall:
Having a custom campaign that fits between Valve campaigns

Cons:

2nd map:
Invisible wall was too “visible”, next to the truck
3rd map:
It was quite unclear how to get to the car at first,  so we all died	

Conclusion:

First, thanks for putting up another host to download.
The map is good, but a little bit short for my likings. Apart from the kinda confusing finale, the map is great.

Pros:

1st map:
The “safe house”s bring a really good climate to the campaign
2nd map:
The mounted gun panic event was really clever, too bad it doesn’t work so well in Single Player
3rd map:
HELL YEAH M60	
4th map:
The extinguish the fire event was pretty clever, though I did not notice water actually coming
5th map:
I felt like I was at the Citadel on that low part
What you did after touching the Monolit = pure awesomeness
Overall:
Tight and cramped spaces should make it quite challenging on harder difficulty
Lightning (or the lack of) were really good

Cons:

1st map:
Charger bots don’t recognize some walls as walls and try to charge through them	
3rd map:
It wasn’t very clear that we were supposed to turn on the power then come back, though the layout of that area made so that I didn’t spend too much time wondering what to do (you could just use a simple message like the “Find a way to extinguish the fire”)
What the heck are CEDA uncommons doing here?	
5th map:
Bots are unable to function with high stairs
Overall:
I feel that the map would be too difficult for the Survivors on Versus - too many tight spaces that a Charger/Spitter can wreck havok.	

Conclusion:

I played this on Single Player on Normal difficulty and it was pretty awesome. It seems like a perfect Campaign to play on Normal/Advanced difficulties, but I think that on Expert and Versus it could become frustrating due to the amount of tight/cramped spots.

Pros:

Feels like The Parish mixed with Swamp Fever
The 1st to second map change of time feels right (because of the fireplace)
The puddle of petrol thing is original
The "lower the bridge" one too

Cons:

Bad FPS
No help text in the first map
First map is kinda confusing
Floating grass (third map)
WTF walkable boat that turns into a crescendo?
The third to fourth map change, while original and all, feels kinda off. Add some lines to that scene.

Conclusion:

I don't like the swamp theme much, and it felt kinda confusing. I still liked the campaign, though.

Pros:

Nice Intro
Really dark
You were able to maintain quite a handful of stuff from the original map
The map makes for some great Vs spots
The Witch in the water
No bot problems beside their usual stupidity
No FPS issues
3rd map crescendo's really good and challenging

Cons:

Unfortunately the way L4D2 is played can't keep all of the original map's puzzles
The cemitery feels kinda underused. There could be lots of Witches there
Witch in the underground is kinda dumb

Conclusion:

Really good port, could use some HL2-like puzzles here and there, but overall it's a great campaign

Pros:

Nice poster
Nice intro
Aperture containers lol
X-Ray with the L4D hand
Lots of hordes
Engenious second map (although confusing, at times)
OMG WATER ALMOST DROWNED
Explosive barrels
Finale succeds where most Scavenge finales fail: verticality
Really difficult
Original design
Nice ending sequence

Cons:

Bots have some problem with the stairs right after the panic event
Bots keep coming out and getting back in the water
Bots blow up the barrel room ;_;

Conclusion:

Loved it.

Pros:

Second map "saferoom" was a nice touch
Solid design
Lots of meele options
Passing stuff
GNONE CHOMPSKI
The toxic waste part can be great in Vs
Bridge part
Rescue map is really long

Cons:

Size (I mean, half a gig? wow)
Easy (if you don't consider bots stupidity as a difficulty factor)
Rain inconsistency
Skybox issues
Invisible walls in some places (mostly around trucks, to block the way)
Although long, the rescue map has too much ammo/medikits/defibs
Tank spawns right in front of the helicopter

Conclusion:

A nice, easy campaign (apart from the finale). It did have a lot of supplies, a lot of meele and a lot of Grenade Launchers, but also a lot of hordes, so it kinda balances out.

Pros:

Nice intro
Golf club
Lots of Special infected
No bot issues
Multiple-ish paths
Ammo/weapons are in the right places
4th map radio
Bridge. That was just awesome

Cons:

No poster
Invisible walls in the beginning (maybe put something actually blocking the way)
Please put something indicating the water will kill you
Too many medkits on the second map
No ammo stash on the second to third saferoom
Windows of the warehouse didn't break with guns, but broke when standing on them (either make it break, or not)
Riot cop made no sense in the campaign
Construction workers also
Hazmat guys

Conclusion:

Guys, just because the Uncommon common are there, doesn't mean they can be used like, in every Campaign. The Hazmat Guys and the Riot Cops tell a completely different story (one being a CEDA evac spot being taken over, and the other being the military trying to work. CEDA and the Military didn't work together).
I don't like the swamo theme much, so there's also that, but, overall, a nice campaign. Keep up the good work :)

Pros:

Multiple-ish paths
Riot Uncommon zombie seems plausible
Maps are easy to understand
Very polished, no FPS issues whatsoever
Has a really good potential as Versus

Cons:

First running crescendo is waaayyy long
Too easy on Single Player
Almost no Tanks
Tank music in the finale didn't play

Conclusion:

Really liked this. Has a lot paths and lot of holdouts in the finale. Unfortunately it's too easy on Single Player, but must be really fun to play on Versus.

Pros:

Nice title/poster
That pool is innovative
Lots of infected

Cons:

Really short
Some bugs in the finale animation
Finale isn't really creative (maybe another model for the car, or something, at least)

Conclusion:

As it's still in Beta, I hope to see improvements in the bugs and all. All and all, the first map is great, finale is bugged, but... it doesn't feel like a new campaign. It feels like a left out part of Arena, if you know what I mean.

Pros:

Nice work overall
New type of map (hadn't seen it before)
No navegation problems with the bots
Multiple paths
Navegation worked nicely on the 4th map
Easy

Cons:

Some FPS issues beggining in the third map
Bodies started desapearing in the fourth map (probably something from my PC)
The fourth map made me dizzy (xD)
Crescendos weren't creative
I don't know if its just here, but the water reflections act weird with the flashlight on
Zombies spawn annoyingly far
Finale is TOO easy
No victory song or whatever

Conclusion:

A nice campaign, with a nice concept and nicely done maps. I STILL feel a little dizzy from the fourth map xD
The finale, however, was boring, and annoyingly easy. Out of luck, the Tank managed to kill a bot by throwing him down, but other than that, too easy.
Also, the lack of song really frustrates.

Pros:

Lots of zombies
An interesting crescendo (BREAKING the barricade, not putting it on fire)
Difficult-ish
No bot issues

Cons:

Random hordes coming from nowhere
TOO bland
Finale is way too easy compared to the rest
Not enough visual aids as to where I should be going (not your everyday arrow)

Conclusion:

A quite good campaign, with some problems that are actually good (like the random hordes), but, overall, too bland. If I were to describe this campaign in one word, it would be "dull"

Pros:

Really nice visual effects
A lot of zombies
Big maps
Nice crescendos

Cons:

"Too much of the same" feeling
One or another bot bug

Conclusion:

I really liked it. It was challenging enough, with the crazy amount of Commons and Crescendos, and the SI really "knew" the map.
The only problem I had with bots was in the 2nd map, at the very end. Rochelle fell down the stairs for some reason and died. (lol)

Pros:

Nostalgia
Well thought changes from the original HL2 maps
Nice L4D2 additions, like the rain effects and the smoke
Easy to navigate (not confusing, but maybe that's because we all played HL2:EP1 xD)
The songs

Cons:

Few bugs:
- Second Tank died for no reason on the finale
- Bots had a little trouble with their navigation at the start, where they have to "climb" a car

Kinda boring finale, could've used the HL2:EP1 path to something actually usefull.

Conclusion:

GREAT campaign, GREAT work, almost no bugs, and the bots AI was pretty ok in here. Nearly perfect campaign :)

Pros:

The custom work is GREAT. The sprays, the voices, everything.
Map design is also good

Cons:

The finale is a little disappointing, though

Conclusion:

I really liked this campaign, and custom work (be it voice acting, graffiti on the walls or whatever) is always good.

Pros:

Puzzles. That's not very common
Portal-like.
Random paths and spawning objects
Really challenging Survival

Cons:

Too short, could've used a bit more challenging puzzles
Bots bug all the time in the pit
Bots move gas cans/fireworks

Conclusion:

A really, really fun map to play on Single Player, and possibly even Campaign. Could have used a bit more challenging puzzles and death pits, because it really is short.

Pros:

Challenging, even on Normal setting
Events are very original
Good amount of paths

Cons:

Too confusing, sometimes
Buggy with the bots (they get stuck in a lot of places)

Conclusion:

I would give it a 95/100 because of the fun and challenge I had with the Campaign on Single Player (can't wait to play with friends), it was a really well made campaign. But the bot bugs just ruined the 3rd map ending, and at first I got lost at the finale, so I have to make it a 90/100.
