Pros:

- L4D1 survivors are epic
- Many items to use
- Great L4D atmosphere

Cons:

- None

Conclusion:

I've never played the original L4D but this is an awesome port and now I finally know what this map is like. Great job!

Pros:

- Good looking maps
- Survivor skins

Cons:

- Easy as hell (GL's and M60's around every corner)
- Very short maps
- Instant death at the beginning of 4th map (machine gunner can shoot into the save room)
- Mines are annoying

Conclusion:

A campaign with a great looking enviroment and the survivor skins make it look even better. However, it's easy as hell as you get new grenade launchers and M60's every 2 minutes and the maps are very (very) short. The mines are annyoing as you get incapped instantly without warning and the machine gunner at the beginning of map 4 killed me instantly while still in the save room.
Wouldn't play this campaign again tho' but I recommend everyone to check it out and form their own opinion on it.

Pros:

- Good level design
- Balanced item placement
- Bots navigate through it well
- Epic moments
- Character dialogues (don't make the campaign seem lifeless and boring)
- Is not 'Cold Stream'

Cons:

- As flunk333 said, the new  melee weapons feel weak
- Hard finale

Conclusion:

A very fun campaign. The mapping is good and the items are placed just right. Not too much and not too few. I had no problems playing it with (Dziggy's fixed) bots. However, the new (TF2) melee weapons really do feel weak and it was weird that they don't have an UI icon (on the other hand all standard icons are saved in one file so I don't know hard hard it is to add new ones). The finale was also pretty hard because of the enviroment, but overall a great campaign to waste some boring time.

Pros:

- Great mapping for the Source engine
- Balanced item placement
- Cutscenes
- Good action
- It's not 'Cold Stream'

Cons:

- None I can think of

Conclusion:

A great campaign to waste some time! The level design is great, consisting of a stunning atmosphere and good item placement. The action is great, the voice acting believable and the cutscenes very funny. Overall a very good campaign.

EDIT: You guys made me watch the 2004 movie and it was awesome to see were you got all that inspiration from. ;)

Pros:

- More realistic enviroment
- Good quality

Cons:

- None

Conclusion:

Great simple mod that makes the game much more realistic. Good job!

Pros:

- Model
- Textures
- Animations

Cons:

- Right hand isn't holding the handle correctly

Conclusion:

Great skin for the default chrome shotgun. However the fact that the right hand isn't holding the handle correctly (looks really bad when reloading) is a bit annoying. Otherwise good job.

Pros:

- Parish at night
- Few interesting map changes
- Great bot navigation
- Fewer items = greater challenge

Cons:

- None

Conclusion:

A great alternative if you're getting bored of the original campaign. The night atmosphere makes it really creepy but also a little harder. The graveyard scene and the bombings look even better at night. The item placement is good; harder than the original but not too unbalanced. Dziggy's fixed bots could navigate through this campaign very well and the few alternate routes invite for an even better experience.

Pros:

- Does what it says
- No need to leave a game anymore

Cons:

- None

Conclusion:

Simple mod that does what it says. For idiots: Changes are only visible when the server changes the map.

Pros:

- Pretty good level design
- Great action
- Nice item placement

Cons:

- Long loading times due to the big maps
- Bots sometimes get stuck

Conclusion:

So far this campaign is amazing. The great level design alone makes it worth playing. There're however some minor problems, one being the pretty long loading times as the maps are pretty big. However, the long play times on each map as well as their design make up for that and the performance is also good on my system. The survivor bots sometimes get stuck but that's also not a big problem as they can teleport to your location after a certain distance.

Pros:

- Great model and textures
- Nice animations
- Not a Valve made weapon

Cons:

- None I can think of

Conclusion:

Simply the best AK47 skin for L4D2 so it was easy to give it a high rating.

Pros:

- A small fix that was required and looks nice

Cons:

- None

Conclusion:

 Why's Valve so lazy? Guess when you can't sell games (Steam) the quality of an update doesn't matter.

Pros:

- Often lead the way resulting in more realistic games
- Faster help when being attacked by a special zombies
- "Killed most zombies with melee weapons: Ellis 36 / Rochelle 26"
- Bots avoiding shooting the player
- Bots are really fun to play with now

Cons:

- None!

Conclusion:

You sir just made the singleplayer experience for this game so much more amazing. I only play the multiplayer with my friends so I don't play it very often. But I often had the desire to play L4D2 and to slay some zombies but how if not with stupid bots that make you ragequit more than a 12yo with a microphone in a random MP game? I just played through the Dead Center campaign with these bots and it's amazing what you did to them. At one point it really felt like I was playing with real players. I thank you very much for this addon and will never play the SP without it! 10/10
