Pros:

-Poster
-Sky is pretty nice
-Perfect map for rushing snipers like me!!!
-Funny Warning signs!!!
-Much to explore, very big levels
-perfect bots
-perfect balance of enemies
-perfect atmosphere
-perfect amount of supplies to make it challenging even on easy
-extreme nice design of the levels
-very good AI for enemies
-perfect tank moments...they come when you need em the least
-perfect map for realism
-perfect from Noobs till veterans like me!!!
-epic finale...best one I've seen so far!!!

Cons:

-in the first big parking area, there are nearly no enemies approaching on easy
-a few very slight frame-rate drops, but not really something that's needing a change
-dialog

Conclusion:

ABSOLUTE PERFECT!!!

That map has it all, action from the finest, scary moments, right amount of supplies to keep it interesting and a epic finale!!! Also if you like to sniper with normal weapons(rushing sniper), than this is a absolute must have!!!
Also on easy it's quite suitable for Noobs as well and I think it's also perfect for realism for more experienced players or veterans like me!!!

Well, that's all I have to say...I'm impressed!!!

Pros:

-dialog
-map 2 trap
-map 3 weather(thunderstorm)
-finale
-suitable for Noobs and experienced players
-nice vent duct effects in map 3...hmmm reminded me a bit at a other  game...ah yes, Half Life
-Nice outro-video(Open Trunk is funny and realistic!)
-enemy balance is nice
-perfect bots
-design
-short, perfect for realisem

Cons:

-Intro(Would be nice to see how the helicopter crashed like this)
-a bit too much hunters(this is no real con, because I#m pretty sure it's to increase the difficulty for experienced players)

Conclusion:

Well, this campaign has everything it needs! Expect a nice Intro-video maybe.

It is a campaign that gives the player everything, action, tensed and scary atmosphere and a nice amount of enemies. Maybe the hunters are a bit too much, but that's what makes it challenging even for players like me.
In my opinion the campaign is perfect as it is!

Pros:

-poster
-enemy balance
-design
-frame-rate
-atmosphere

Cons:

-riddle objects did not showed up for me
-crashed in safe room on loading map tow(keyboard and mouse controls for player froze and I was not able to move my character or do anything)

Conclusion:

Well I only placed the first map and it will stay like this, because the riddle objects are not showing up for me. Since this is a Beta version, this review is only temporary, until someone fixes the campaign. It has some nice ideas, but needs bug fixing badly.

I hope that it will happen, till than it is rated so low, because of the trouble I've had even finishing the first campaign.
;3)

Pros:

-Poster in 16:9!!! Awesome Poster!!!
-Short but nice Intro
-Very good bots
-nice traps at the start!!!
-fuel trucks can blow up EPIC!!!
-first elevator is the best elevator I've seen so far int this game!!! Perfect work!!!
-collapsing floor is very surprising, specially because a tank approaches!!!
-much tanks, pretty nice
-well, I thought I've seen the greatest possible horde already...I was so wrong. It is here, very, very nice!!!
-the amount of supplies and enemies is balanced perfectly, to make it extremely challenging even on easy. It seams there are too much supplies at first...but you#ll need them!!!
-witch invasion room is kinda nice!
-for very experienced players only, even on easy!
-automated gun turrets are perfectly made...they shoot only zombies. awesome to the absolute max!

Cons:

-bots are a tiny bit stupid...specially on the boot trap issue to climb out again. Also in map 2 at the start, they die easily.
-balance of enemies, just a bit wrong...too less Spitters, but no biggy.
-map 3 too long
-map 3 finale too hard...too many witches
-map 3 toilet witch is really, extremely mean but i liked it!

-Only for really experienced players, not for experienced ones, even on easy or normal(but you mentioned that in the description, so this con not really counts in my judgment).

-map 3 is way too long for it's finale, because someone dies for sure in the witch-room to safe the others. Either add more open space to move or a safe-room and split the map into tow. Also this room makes it impossible on realism mode, as long as it's the finale of map 3(suggest adding more defis outside of the witch-room you have to pass).

Conclusion:

Well, the map and it's design is kinda awesome! It also makes a really, really tensed and scary atmosphere(I love that!!!). Also the traps a perfect programed and very surprising! I really loved the hole map, but I'm considering myself as a veteran when it comes to experience of L4D2.

But as cool as it is, I have to join the other reviewers and say, the witch room needs improvement(suggestions to improve in the cons). I played it with four others on normal and we barely survived it till map 3, were tow players left because of the witch room. But one player stayed and with me dieing(got revived) and one bot staying dead, we made it past the about 20 witches that were in our way. :3))

The finale was not awesome...it is epic!!! This should stay as it is!!!
All in all a great map for veteran players, that made it into my heart as one of my favorites!!! Great job!!!
But please improve map 3, so you have more room in front of the witch-room, to kill the witches!!!

Pros:

-perfect enemy balance
-perfect bots
-perfect amount of supplies
-no bugs
-epic finale
-only noticed the alarm warnings twice, when it was too late, because of the amount of zombies and the extreme tensed atmosphere this nice campaign has
-perfect frame-rate and level design
-good directional infos
-perfect map length for realism!!!

Cons:

-felt too easy for pro, as we played it from the second level onwards
-no dialog

Conclusion:

Well I played it with a very experienced playerness that normally only plays realism. We played it on normal till close to the end of level 2 and switched to pro for the rest, but it felt to easy for playing with tow bots. Or maybe we are the perfect team. :3)

I was talking and got distracted, just before the train arrived and got killed by a tank/boomer/jockey combination, what makes the finale awesome, because it's packed with perfect balanced enemies!!! But the rest of the campaign was too easy to survive for my taste, on pro.

But the atmosphere is tensed and pretty scary, so I really love this campaign!!!
Have to test it on realism and pro/extreme to make my final judgment.
But till than, it's a crystal clear 10 in my opinion!!!

Pros:

-poster
-intro
-extremely nice designed level, that takes you to the most memorable places of MGS1 and 4!!!
-perfect enemy balance
-good difficulty
-much re-spawn cabins
-good amount of supplies to make it challenging even in easy or normal.
-cameras alert the horde! Epic!
-very nice and bug free elevators!!!
-final is epic and challenging, even if the bots have trouble getting to it!

Cons:

-as big as I am a fan of MGS, I must be neutral and so here come the cons. :3((
-bots are the stupidest I've seen so far! They die in nearly every map and also kill everyone in the second level very easy
-level 1 elevator alternative way is so buggy you'll die for sure with bots! On the upper exit of the alt. way the bots fall down very easy.
-skins for the survivors would been a blast, also weapon skins
-the electric floor need improvement very badly
-no extra dialog

Conclusion:

I love MGS so it's kinda hard how much errors this level has, but the design nearly makes up for it and also the final. It's made quite perfectly and takes place after MGS4.

I really beg to improve this level, because the design and stuff is so good!!!

Pros:

-Poster
-balance of enemies is very nice
-much tanks and witches
-nice start and finale
-a level for a fast campaign play, also nice for realism
-the container ship is very nice, because of the vibrations you always think a tank approaches!
-the alarm car falling out of a container
-atmosphere is epic
-level design is epic

Cons:

-felt too easy on easy because of to much ammo
-dialog

Conclusion:

A very nice level for all! there is nothing missing, may one or tow special dialogs were nice but they don't matter here. This campaign is awesome and epic to the max, it has much action and a scary part too!
Specially the enemy balance is making this campain a perfect one, but the rest as well!

Kinda funny thing were you exit the container ship...reminded me at the movie "Poseidon".

Pros:

-awesome start level
-very good balance of enemies
-bots are perfect
-the atmosphere is not scary, but supports the action orientated map very well
-the frame-rate is very nice for such big levels
-the train scene is epic!!!
-right amount of supplies, to make it challenging, even on easy!!!
-good final
-nice stadium
-cool quarter-tanks!
-normal tanks in the game

Cons:

-dialog

Conclusion:

If you like action, than this is a perfect map! I like scary more, but was kinda amazed of the details and stuff int this map. But it not scares you even a tiny bit, because there are very few scenes in the dark...

Pros:

-Intro...short but very nice!
-dialog...awesome!!!
-funny radio massages and stuff
-nice sniper invisible wall at the start
-it gives the word horde a complete new meaning!!!
-perfect balance of the zombies!!!
-you will never see so many tanks as here, in a finale, I guess. ;3)
-very detailed
-perfect bots
-no bugs
-nice frame-rate

Cons:

absolutely none!

Conclusion:

Well this campaign is not really scary, but it is packed with action from the finest! It is also a bit long, but that's okay. In fact it's the best campaign I played so far, even if I like scary ones more, but this one is simply, amazingly perfect and very well done!

Pros:

-Very detailed rendering
-Mostly Bug free
-An HD remake of Silent Hill like I always wanted one
-Very long
-Extremely scaring from the first minute on

Cons:

-Bots take no weapons/med packs and act really stupid
-Fell trough the floor bug in the campaign after the last school level
-The per-last level "Nowere" is a pain in the ass, because the riddles are buggy and also the bots fall of an edge often

Conclusion:

If you liked silent Hill 1, you'll love this campaign. I played it with friends, so we were able to survive it...but for my taste it's a bit to hard for higher difficulties, because you find not much stuff, even on normal, as we played it!

Pros:

-very good bots
-very detailed
-nice riddles
-nice dialog
-cool videos
-perfect frame-rate
-good amount of supplies/ammo

Cons:

-the intro is so long it's simply crazy...that should be mentioned in the description, so you can skip it.
-Decisions, Decisions Part 1 and tow!
-In Part 1, the leaver for the clock is nearly impossible to find without looking into the y-tube walkthrough ...I must know...searched about 1 and a half hour for this, than I gave up and look on Google!!!
-In Part tow, the second sewer leader is so bad, that the bots are going back and leave you alone to die. You have to run back trough the hole thing...boring to the max!!!
-also in the sewers, the zombies mostly fall into the water and die...tried to rescue a bot falling into the water and could not find a way out.

Conclusion:

Very good level, specially for people who played the game it's based on, because the Outbreak files were a real torture in the original! But it defiantly needs improvement in the last parts!

Pros:

-amazing scenary
-nice bots
-nice dialoge
-good enemy balance
-nothing for claustrophobic...but that's what makes it really scary and challenging!
-finale:it's hard to reach the point of rescue with the hole group

Cons:

-one word:finale
-charger always kills one or more because he rams you and falls off the ship, but the respwarn room counters it, so no biggie
-the finale is way to easy, because you can kill everything that approaches from the tow cranes and goo back for ammo even with bots only

Conclusion:

Me and my best buddy liked the level, because we survived...but the horde hindered us from rescuing the hole group. We died because we tried the first tow times...but the bot was always to slow. but all in all an epic, nicely done level!!!

Pros:

-very nice locations and extremely detailed
-bots are perfect
-cool locations
-nice dialog
-perfect finish on the Donauturm!!!
-cool...a ride on the speed-tram(S-Bahn)!!!
-catacombs under the Stephans Dom(e)!!!
-perfect enemy balance!!!

Cons:

-the subway-tunnels are not correct, the U4(underground 4) is not even close to the catacombs of the Stephans dom(e), but nicely done any way. If it should be the U1 or U3, the color is red(U1) or orange(U3) and not green. LOL

Conclusion:

This can only be described by one word: PERFECT
Nothing more to say

Pros:

-very detailed
-nice ideas
-cool start and finish
-good locations
-perfect enemy balance
-much dialog, even if you can not understand it, when you can not speak Spanish, but it makes a nice atmosphere anyways

Cons:

-FRAME-RATE DROPS(in nearly all maps)
-surges like hell in most maps...not playable for lower PCs I guess.
-Hard to make scene what to do next in Spanish, specially in the second level!
-very much problems with the frame-rate, specially when someone joins...surges like hell some times!
-The bots are okay, only on the elevators they screw up a lot.
-nearly unplayable in the last chapter, because the frame-rate drops so often.
-levels to big or let's say it's hard to find the way trough them

Conclusion:

A map that need much improvement, but has a very nice concept and also is holding what it promises. SG1.

Pros:

-very detailed and nice scenery...I must know, because I lived in Vienna my hole live.
-bots are okay
-enemy balance is perfect
-the ending is short but haunts you in your dreams. Perfect!
-dialog is okay, some of it is quite funny, specially Zoie!
-nice storm effects in the zoo!

Cons:

-sometimes hard to find out were to camp when the hord is approaching.
-too log time till the last elevator
-were are the other zoo animals? I only saw a dead elephant.
-the parliament is kinda hard to reach, because of the glitchy ways on the buildings

Conclusion:

Very good level, I liked it and it's also playable in all difficulties thanks to enough supplies and ammo. Only the finale is kinda stupid, because you never survive the about 12 minutes it takes till the elevator is ready, on realism mode. I loved the scenery but hated the parts on the buildings to the parliament. but the bots mostly are very nicely programed. Also nice surprises with the characters!
