Pros:

+Animations
+Reload Animation
+Oozes Quality
+Textures
+Optional Variations (the ACOG, EOtech, etc.)

Cons:

-Useless Foregrip (-0.3)

Conclusion:

I've used this skin for several months and it still holds the same amount of charm when I first downloaded this. Animations are fluent. The reload animation is a lot better than the default.

My only complaint is the cosmetic foregrip. A nice touch, but the survivors do not use it! However, I'm glad that the hand does not clip into the foregrip. More points would have been taken away if there was clipping.

Bottom Line: Very Good Mod

Pros:

+Custom Model
+Custom Sounds
+Animations
+Scope

Cons:

-N/A

Conclusion:

This is a great reskin. Everything is custom-made. I especially liked the refection on the scope, very nice touch. 

However, if I were to nitpick for a con, it would be that the rifle looks like an AK skin that I have installed, But no points will be taken off because of that.

Other than that, very well-made skin.

Pros:

+Model
+Texture
+High Quality

Cons:

-No Custom Sounds (-0.5)

Conclusion:

This is a good skin. I like it. It has almost everything you would want in a custom skin/mod; the model, animations, textures, the overall look, etc.

The only thing this mod/skin is missing is there are no custom sounds. Which for me plays a big role with mods/skins.

Overall, not bad. Would be better with custom sounds.

Pros:

+Model
+Animations
+Textures

Cons:

-No Custom Sounds (-0.5)

Conclusion:

This is a good skin. I like it. It has almost everything you would want in a custom skin/mod; the model, animations, textures, the overall look, etc.

The only thing this mod/skin is missing is there are no custom sounds. Which for me plays a big role with mods/skins.

Overall, not bad. Would be better with custom sounds.

Pros:

+Everything is custom made
+Foregrip

Cons:

-Reload animation (-0.2)

Conclusion:

This skin is awesome. It just oozes quality. You could tell a lot of work went into this skin. 
The survivor actually uses the foregrip. Unlike other mods where foregrips are just for show; Very nice touch. I got to give you props on that.

The reason I put the reload animation as a con is because the actual animation seems a bit slow. It doesn't seem as fluent as it should be. However, I can get over that.

Everything else is awesome. I will be using this skin.

Pros:

+All custom
+High quality

Cons:

-Lots of hand clipping

Conclusion:

This is a good mod. Everything is custom-made; The sounds, the models, the mag., the textures. I could tell that a lot of work went into this mod. This skin reminds me of the Patriot gun from the metal gear series.

However, the hands clips a lot with the c-mag, and that basically ruins it for me. 
Still not a bad skin.

Pros:

-Custom Model
-Custom Sounds
-Custom Animations

Cons:

-Model (See Conc. for details, -0.4)

Conclusion:

This is a good skin. It's the same type of gun, but it has a different look (which are my 2nd favorite type of skins). I like the extra shells that are on the side of the gun, very nice touch.

Now, the reason the model was listed as both a con and a pro is because sometimes, the model seems a little cartoonish. It does look nice and it does look nicer than the default model. But get rid of the cartoonish quality and it would be perfect!

And the flashlight on the gun looks kind of unusual, but I won't count it towards the score. I can get over the weird looking flashlight model.

I'll still use this mod though. Very awesome mod.

Pros:

-Animations
-Sounds
-Detail
-Model

Cons:

-Couldn't find any

Conclusion:

This is a very good mod. Everything was custom-made. the animations, sounds, models, etc. This is, to me, the perfect skin for the hunting rifle. It's so fitting.

Although, if I had to nitpick for a con, It would be the rifle seems a little out of place in L4D2, like as if it doesn't belong there. I'm guessing it's because this rifle was from WWII and L4D2 takes place in modern times. But I won't count it against the score.

Pros:

+Good Campaign
+Lengthy
+Detailed
+Great Finale
+Events

Cons:

-Invincible Tank at the finale (-0.3)

Conclusion:

Not a bad campaign. I liked the Finale and the way it was "structured." Now the problem I mentioned in the con didn't affect me; It only affected one of the friends I was playing with, it was invincible only for him. But I still see it as a con seeing as how the tank should be vincible. Other than that, everything was fine. Nicely paced, nicely made, etc.

Pros:

+Simple, yet effective
+Brighter than the default flashlight

Cons:

-Can sometimes cause glare on some surfaces (-0.3)

Conclusion:

I have had this mod installed for several months and I have got to say that it has never failed me. But, sometimes the flashlight can cause glare on, for example, a white wall. It's a good thing that the glare ain't that severe. Still very well-done. I still use it to this day.

Pros:

+Well-made
+FPS arms
+Jigglebones
+Fitting

Cons:

-Can't find any

Conclusion:

This skin ain't half bad. She looks more appealing in these clothes. Usually when I see Rochelle, I think "Ew...". With this skin, I think "Not bad". This skin also does match Rochelle. Good Job.

Pros:

+Fitting
+Perfect Match for Coach

Cons:

-Warning: Contains no chocolate or cheeseburgers.

Conclusion:

These clothes for Coach is just perfect. He doesn't stick out anymore like he did with his old set of clothes. Very well-done.

Pros:

+Fitting

Cons:

-Doesn't loop

Conclusion:

This is perfect and fitting for death music, my only complaint for this is that the music stops after a few minutes of playing, it doesn't loop or anything like that; fix that and it would be perfect.

Pros:

+Animated Healthbar
+Icons (Both Survivors & Items)
+Weapon Icons
+Not too complex
+Not too simple

Cons:

-Animated Healthbar seems a little..."odd" (More info. in the Conclusion).

Conclusion:

I like this HUD. It has everything I'm looking for in a custom HUD. As mentioned in the cons, the animation in the healthbar doesn't seem fluent. Everything else is very well done.

Pros:

+Sounds
+Nice models
+Animations

Cons:

-See conclusion for cons.

Conclusion:

I think that this is a very good mod. I would prefer the regular sized UZIs, but that's just a personal preference. 

Although, if I were to nitpick, the guns look a bit...odd in the game like as if the gun is too small for the survivors. Everything else is great though.

Pros:

+Felt like an official campaign
+Plenty of weapons
+Not too hard, not too easy
+Has all the traits of a good campaign
+"Rescue" Vehicle

Cons:

-Finale (-0.5)
-found too many pickups (-0.2)

Conclusion:

Not a bad Campaign. I thought the finale was a bit too wide open. And me and my friend kept finding pickups (like mollys, pipes, pills, but that's just nitpicking). 
When I saw the rescue vehicle, I just laughed XD

Pros:

+Animations (See Conc. for more info.)
+Custom Sounds
+The Overall Quality

Cons:

-N/A

Conclusion:

This is an awesome skin. I will be using this for now on. The animations are smooth and fluent. I especially liked the reload animation for the dual pistols. The custom sounds are realistic. and the overall quality makes me want to use the pistol over my usual shotgun. I left the cons empty because I honestly couldn't find any faults with this model (or models if you count the dual pistols). Excellent job.

Pros:

+Lengthy
+Detailed
+Not too difficult, not too easy
+Very well made.
+Ample level of supplies

Cons:

-Too much Tanks (-0.5)

Conclusion:

A very good campaign. Although, I think that this level could do without less tanks. Seriously, me & my team had to face about three, maybe four, tanks in each level. Other then that, Highly Recommended campaign.

Pros:

+Fun
+Creative
+Challenging
+Not too short & not too long
+Finale

Cons:

-Too much tanks

Conclusion:

While I was playing through this, I fought at least 2 or 3 tanks in each chapter/level. It started getting old after facing the third tank...in the first level/chapter. But other then that...There wasn't anything else wrong with it. A very good campaign, a must-play!

Pros:

+Fun
+Challenging (had to play it on Normal)
+Finale
+Original Crescendo Events
+Good Weapon Placements
+Detailed
+Creative

Cons:

-Not enough Throwables
-Finale
-Tanks during Crescendos

Conclusion:

This was a very enjoyable map. And the reason the finale is both a con & a pro, it's because it can be alittle too hard. I don't want to spoil it for an future readers that might not have played this, but let's just say you run from the one side of the finale to the other and that can be pretty hard. I had to start all over thrice. But anyways, this was a good custom map. Go play it.

Pros:

+Has that HL2 feeling
+Lengthy
+Challenging
+Combine Corpse :D
+Finale

Cons:

-The elevator event should have lasted longer. In the original game, The elevator felt like it would never come.

Conclusion:

A very good Campaign. This campaign is pretty much about 75% of the original game...which is a good thing 8D Go play it.

Pros:

+Its Lord Of The Rings
+fun
+L4D1 Survivors :D
+Music from the movie
+Very Fun
+Detailed
+Oh, and did I mention FUN!!!

Cons:

-L4D1 Survivors doesnt follow us D:
-No laser sights (but that's just a minor con. Preferred, but I could go without them)

Conclusion:

This is a really good map. It has everything you need to survive (expect laser sights). I only lasted for about 15 mins., but that was because I just mess around whenever I play this map. Highly recommended :D

Pros:

+Feels like an official Campaign.
+Lengthy
+The event in the last map involving a car & water (not the finale).
+Not too hard & not too easy
+The Rescue Vehicle

Cons:

-Too generous with the throwables
-Same thing with the Tier 2 Weapons
-the bots stopped following me after the event with the car and the water (See the conclusion for the full story).

Conclusion:

A very good campaign. Highly recommended. Go grab it and play it.

Anyways, After triggering the event, Zoey got smoked from up above. I killed the smoker. Zoey falls down down below into the water and she gets swarmed, eventually getting incap'd. I go down to try to help her but I get incap'd too. Then my friend (playing Louis) and Bill jumps down. 
Me & Zoey get back up. Then, me & my friend goes to leave. After awhile, I noticed that Zoey & Bill were still down in the water. They kept running around in circles. Eventually, me and friend just ignored them and decided to leave them behind. 
Soon we both get killed by a tank. After that, me & my friend had to start over at the beginning of the level.

Pros:

+Lengthy
+Fun
+Creative
+Good Crescendos
+The Jukebox in the Store

Cons:

-Ellis wouldn't go down the well, so I had to incap him and then wait for a horde to come and finish him off.

Conclusion:

So that is pretty much the only problem I encountered when I played. Other then that pretty good campaign.
