Pros:

This map is simply phenomenal, I absolutely loved it.

Lots of custom content, music, models, etc.

Exploration encouraged

Beautiful world and unique settings

Pro-voice acting 

Cons:

If you're not really good at L4D2, I can see you losing alot in this campaign, as it isn't easy nor short. 

Levels can be a bit dragging played on expert/hard eight.

Conclusion:

I haven't tried the newest update of this campaign, yet.. But I've played the release and this map is truly a masterpiece. It's one of the few maps I've played over and over, and apart from the long levels, it's fairly easy. The world's crafted to a fine design; I thoroughly enjoyed the story-driven aspect of the maps/campaign. 

The does challenge you to a certain level of expertise though, as levels are long and expansive, ammo is 'sort-a'-ish scarce. There are a couple of difficult but not impossible horde events and tank encounters that might come across as stunningly hard, but I absolutely loved the challenge. 

I never found a point where I couldn't pass apart from getting lost a few times here and there. The finale was a tad too easy I thought. 

Overall, this is a brilliant creation of a campaign.

Pros:

+ Incredulously beautiful re-skin of our con-man
+ Completely overhauls Nick with detailed small touches
+ Hi-Res textures

Cons:

- Eranthis' custom incap panel conflicts with quite a few HUD mods out there.

Conclusion:

Mafia Mobster adds a whole new look and feel to Nick's persona. I'm just not a big fan of Eranthis' incap panels.

Pros:

+ Yay! People are actually taking requests and doing them! 
+ It's the real Jason Brody from Far Cry 3
+ "The model has: FPS arms, HUD icons, Facial expressions, Eye tracking"
+ Nice textures
+ Has his name replaces Ellis 
+ He's got real nice hair to look at :O

Cons:

- Missing eye textures? I dunno but my Jason Brody is missing some eye textures
- Strange shoulder jutting out issue holding a two handed weapon (I noticed with the hunting rifle)
- Uses Nick's animations (well, it's not really a con)
- Sometimes he just opens the center of his lips rather than opening his mouth.
- His facial expressions just aren't.. good.

Conclusion:

Props to releasing a working and fully functional Jason Brody! 

The model needs some work to really be good. Those cons just make him really displeasing to look at. His model looks kind-of strange to me, but people are shaped weird, so what-eves. 

Pros:

Highly detailed

No HUD consideration so no conflicts, awesome

Matches all of the ZombieTools weapons

Cons:

Meh

Conclusion:

It's a perfect weapon for a zombie apocalypse. 

Pros:

A powerful, effective script that makes the game more Resident Evil gameplay-wise

Makes 3rd person gameplay much more appealing

Cons:

sv_cheats has to be used to obtain full effectiveness

Conclusion:

Personally, I don't like the dot crosshair, but that's just me. It makes third-person shoulder great!

Pros:

Well shit, that's scary good.

Has blown up model

Cons:

It's textures aren't perfect but... eh.

Conclusion:

Scary, disgusting, it fits well into the boomer.

Pros:

Magnificent weapon!

Hi-resolution!

Animations are awesome (they also match 3rd person reload anims very well)

It's a "smaller" file size for such a good weapon, which is awesome since most good gun models are huge files.

Cons:

Personally, I don't like the animation in which you take out of the hunting rifle, but that's just me. It feels awkward for me. 

Conclusion:

It's a great hunting rifle model; everything's well polished. 

Pros:

 - It actually adds darkness rather than setting on a filter to make the campaigns darker. 

 - You actually need your flashlight most of the time now!

Cons:

 - It does conflict with menu addons (ex: Urik's Game Menu) like the author says: "disable any addons that adds menu items."

 - The FPS model is unaffected by mutation/mod; in a place where there was originally lots of light if you turn off your flashlight your hands are still lit up as if you're standing in the sun (FPS model only.)

Conclusion:

This mutation adds darkness without having to downloading a "Dark" campaign map for every campaign you want to play in the 'dark.' It does exactly what it says it does and it's a simple and really cool mutation. You could go for the non-instant kill witches but that's just a personal preference. I suppose you really can't do anything about the FPS models and their lighting though, so no points taken off.

Pros:

New animations with reloading
HQ textures
Beautiful world model

Cons:

Makes you want to use it above all other guns because it's so good

Conclusion:

A simple, powerful skin for a powerful gun. Very much recommended.

Pros:

The plasma cutter has a very nice world model, and it goes along great with the Issac Clarke skins. 

Cons:

1. The plasma cutter has low texture quality making it stick out badly in FPS view (if your comp runs on high graphics.)

2. The animation should be changed so that, when fired, it recoils back like the real plasma cutter, not upwards like a gun.

Conclusion:

It's a nice mod, it could use a bit of tweaking here and there, and you can find the sound mod for the gun elsewhere on the site. It's just the animations and low textures make the gun rather ugly to look at from the FPS viewpoint. I don't use it simply because it's animations don't match the real plasma cutter, but, it's a must have for Issac Clarke skins or Dead Space fans.

Pros:

GORGEOUS!!! 

I've always been picky about dull eyes and this makes some of the smallest adjustments but really brings out the character in the survivors.

Cons:

Ellis and Zoey's eyes seem like they're glowing. Zoey more so than Ellis (from the screenshots.) I suppose this isn't really a con.

Conclusion:

If you've got a great looking HD skin, this would be the perfect last touch to any skin.
