Pros:

   - Very well made. You clearly took your time to make sure the details were there.  Only minimal glitches.
  
  - Good atmosphere

  - Plenty of original / unique content

  - Challenging and a good length

  - All around fun campaign!

Cons:

  - Inconsistent difficulty.  At the beginning it is too easy with ammo every couple feet, then it gets very hard out of nowhere with much less ammo.

  - The long ladder going down the well in map 4? Cool but all 3 bots fell, 1 got stuck in a falling loop until he died.  Then no hero closet until after the elevator is activated.

  - Confusing 4th map.  I get the elevator needing power so you go back and flip the switch but then there's no help.  After I was about dead I tried the generator.  Why is a generator needed when the power was turned on and why is everything else glowing except that?

Conclusion:

   All in all a very fun and well made campaign.  I'd say a little less ammo and more difficulty in the first couple maps and then a little more clarity in the later maps with a few glitches ironed out.  It can be confusing at times but I always found my way pretty easily so I won't complain there.  Nice job!

Pros:

   - Great custom sounds now that they work
   - Good voice acting on a custom campaign for a change (see Centro)
   - Good spacing of weapons and ammo
   - Not linear, actually have some options which way to go for a change
   - Nice intro and toilet cut scenes
   

Cons:

   - Nothing particular really although I'd like to see if for L4D2 more than 1.  

Conclusion:

   Great job!  I was very disappointed when the rebuildaudiocache command screwed up my sound on everything.  Turns out it was Valve so I re-installed the game and it was fine and the custom sounds are excellent.  Very fun campaign!

Pros:

  - It's Dead Air for L4D2
  - No major bugs
 

Cons:

  - Scavenge for the finale, UGH. Might as well make hide and go seek the finale.
  - Besides the scavenge being a lame finale, it was way too easy.
  - Night work on the finale was just not good. Making the finale night time seems pointless.  It's not meant to be a scary atmosphere like other parts.  I would just leave it.
  - Barely any creativity.  Only 1 change in the path that I noticed and that was cutting out 90% of the garage?
  - Special infected spawned behind the fence that the van breaks down in the terminal event.

Conclusion:

    As a map Dead Air gets a high rating but since you didn't create the campaign I'll only rank it on the conversion.  I'm glad you did it so thank you however a little creativity would not hurt.

Pros:

  - Creepy sounds
  - Nice length
  - Good separation of healing / weapons / ammo mostly
  - Disappearing furniture / floating lamp / flashing lights
  - Faces flashing
  - Gave props to Night Terror
  - Waited until it was complete to release it!
  - The moon

Cons:

  (These are more suggestions than cons)

  - Too many kits on the first map
  - Bots can't get to the ammo in the tunnel
  - More sounds in the first map
  - More of the creepy feel in first and last maps 

Conclusion:

    Excellent campaign, I loved it!  I only saw 1 thing unfinished however I only saw it the 2nd time I played, not the first.  That was the fireplace in the house.  Myself and a friend saw pink and black but our 3rd person did not.  This was a lot of fun and definitely has replay value.   I'd like to see more of the creepy feel though, maybe through music or more sounds, especially in the first and third maps.  Great job though!

Pros:

  - Just enough twists to make it different
  - Ammo and explosives spaced just about right
  - Made the finale fun even though it's an old idea
  - Well made, no glitches that I saw 

Cons:

   - Fairly typical type of campaign
   - Some confusing areas that didn't make sense (ex: the long warehouse type building with 3 sets of staircases.  All of that looks the same.  Could have used some more decoration

Conclusion:

    A very solid campaign, better than a lot of the stuff that has been coming out lately.  I liked Lost and Carried Away a little more but this was very fun.  This is 1000 times better than Greyscale who people rated higher for some unknown reason.  Nice job!

Pros:

    - Pretty well made
    - Lots of weapons
    - Long
    - Different in some parts

Cons:

   - Ending (see conclusion)
   - Maybe too many weapons and not enough ammo
   - Not all that different overall

Conclusion:

      Damn you people and f'ng up a decent campaign with something stupid.  The finale........get to the car........really?  That last map was massive and there were 50 cars with their lights on.  I did the finale up on the tower with the 50 cal and had absolutely no clue where to go.  Breezed through and still survived running around in circles looking for some obvious sign of  a "car" only to finally be caught by the tank.  Start over the last map?  Don't think so.

     Overall nice map though and someday I will play again and still probably won't know where the "car" is.  Maybe if I do the final right at the handle used to start it the mysterious car will show up.

Pros:

 - The ride part was amazing, well done!

 - Love the music and the voices

 - Very challenging in parts

 - Love the cave ins and forced alternate routes

Cons:

  - Needs another map or 2, too short overall

  - Not sure if it was the server I was on or not but the 2nd time I played which was after the latest update, the sound was not as clear and garbled in some places.

Conclusion:

   Extremely fun campaign!  I can see you spent a lot of time on the detail and it pays off.  I don't know if you are done but I'd love to see at least 1 more map added on the end, maybe with a puzzle or something to complete.  Nothing too crazy hard though lol.

   Love it!

Pros:

 - Well made, no bugs I could find

 - Creative.  Several different ways to get you where you need to go

 - Very well done visually.  It was fun to see what came up next.

 - Fair with the weapons and med placement.  Maybe some ammo on map 4 though : )

 

Cons:

- Not finished! : )

Conclusion:

  I really enjoyed this map and will definitely add it to my favorites when it's done.  Great job!
