Pros:

+gman
+hl2:ep3 delayed forever
+gman
+one more reason to use crowbar in l4d2
+gman
+have i already mentioned gman?

Cons:

-nope.avi

Conclusion:

gman in l4d2 caused super time paradox because gman was supposed to be main character in left 4 fortress - strike 3: super hat edition.

good job anyway

Pros:

+Heavy Weapons Tank!
+smoker is briliant
+all voices are working great

Cons:

-scout is quite anoying after some time
-i dont know some characters, so i cant judge them (no points taken)

Conclusion:

it goes 96, just because of scoot.
Every SI sound works perfect, and Heavy Weapons Tank is best of all.
good work.
keep it up :)

Pros:

-Looks awesome
-New theme
-It was hard to spot in distance during storm on hard rain, i had nice suprise later ;)

Cons:

-Theme doesn't fit the game

Conclusion:

Generally its great new skin for tank, theme is not really good but you can replace it/remove it so there is no problem.
if you feel bored with old tank, download this one.

Pros:

-portal style!
-hard
-ending!
-design of maps
-gascan system!

Cons:

-some parts are unbalanced
-"breaking floor" puzzles are way too hard when playing with bots
-bots go crazy in some parts
-maps look little too boring

Conclusion:

this campaign simply feels like portal, however it does not look that good. maps are designed well, but lack detail. Puzzles are simple, and sometimes brutal when you play with bots. campaign is challenging, and for most time fair. another good thing is gascan system you are using to "buy" weapons and items, it requires tactical thinking to pick correct items. generaly this campaign is very good, but it lacks something special, maybe new version will change it.

Pros:

-Very original concept, we need more maps with it
-barricades
-music
-fun
-tech tree is very good idea

Cons:

-when you research throwables, especially boomer bile, game goes really easy because you can spam
-arming bots and refilling their weapons
-rocket
-tech tree should be balanced

Conclusion:

it's great map if you need a break from original campaigns and you want to slaughter some zombies. however tech tree is unbalanced and my main tactic was: get boomerbile --> throw at zombies --> get another one --> build rocket piece -->get boomerbile and it goes...
still this map is definite "must play" for everyone. there would be more than 84 points if not technical issues (tech tree and rocket).

Pros:

-Very good mapping work!
-custom sounds
-'Saturn' shop

Cons:

-you need some improvements in first map
-tank respawned JUST AT THE BLOODY BEGINING OF MAP!!!

Conclusion:

one of must play maps that could be map of the month

Pros:

-Aztec style!
-Boss!
-Fun with friends...

Cons:

-...but not with bots
-Glitches, there is one place on map where zombies CANNOT kill, even boss can't do much in finale

Conclusion:

It's really good map and fun to play it with friends, but not on your own.

Pros:

-Very good port
-Talking survivors
-Plenty of items

Cons:

-It's too bright
-Finale is broken and way too easy
-Forced panic event at 4th map

Conclusion:

This map has some bugs but it's still good old dead air.

Pros:

-Panic events are great!
-VERY balanced difficulty 
-no missing textures/purple checkboards
-Navigations is really good

Cons:

-Where is crazy monk? :D
-Fire is too thick but maybe its just engine failure
-You could make it less linear
-Finale has a bit too much open space
-Lack of engines with rotating blades

Conclusion:

It's simply great map that takes one of the best chapters from Half Life 2 into dimension of Left 4 Dead 2
You must play it.

Pros:

-Very good conversion
-Good panic events
-HL2 music
-I played it with my friend on splitscreen and he couldn't get to train because tank killed him :D
-Very good 'antlion' panic event
-It feels like half life...

Cons:

-...but not as much as it should
-sometimes you could use more debris on map
-elevator panic event is way too short; in Half life it felt like ages before this elevator came out!

Conclusion:

Very good and enjoyable map with few bad things that shouldn't break your fun with this map, it's best played with friends!
