Pros:

High Def Texture
No Mesh issues

Cons:

None

Conclusion:

One of the greatest game series ever made gets to have a port of one of it's mutants into Left 4 Dead 2. Fits the game perfectly, makes me have to use my eyes even more so I can pick him out of a pack of zombies since he sets in nicely with the background. More than just a reskin and forget, now to add the sounds from the game.

Pros:

Feels so much better
Doesn't look so stiff
Reload animation is awesome 

Cons:

None so far

Conclusion:

Valve needs to fire their animation team and replace them with you. 

Pros:

A great map, with details everywhere
Great weapon spawns
Great mix of grenades
Nice and long
The overall progression of the campaign 
A sniper spawn on the top floor on the 1st level by the window, nice touch 
Nice Easter Eggs
Great starting location 

Cons:

Serious Lack of Spawn Rooms 
Finale on Expert can be tricky even with Bile Bombs 
Tanks spawning at the Finale right when you go up 

Conclusion:

A solid campaign, don't die without a defib though, Spawn closests are pretty much nonexistent. Some messed up tanks spawns, like at the plane wing drop off and on top of the fountain, but aside from that, no issues what so ever. Beautifully detailed, a great start that's different from any other, with other people and models for once!

Pros:

Great model
Textures and mesh fit the characters hands
Reloading animation
Animations in general
Reminds me of STALKER, considering porting a texture of that over, to match the apocalypse scene

Cons:

None, anymore. 

Conclusion:

A better AK 47, but we already knew that. Nicely done, animations that look natural as opposed to quirky and weird all together like valves stock animations. Another great piece from Arby. 

Pros:

Great detail for the SI
Makes them look alot more realistic, gritty
A great update, all cons gone aside from one bug with FX in the separate files 

Cons:

When using the Boomer FX mod, when boomed on, there's no actual animation, it's as if you're not boomed on what so ever, and it feels more like a unfair advantage even though you could see through the bile just fine with the vanilla animation 

Conclusion:

Any overdone specials are now fixed, and I would recommend using this over vanilla any day. Separate VPK option in change log is a life saver

Pros:

Adds a more Tactical Feel to the game, though slightly over doing it
A replacement mod that actually fixes the arms!
Great Quality Textures 

Cons:

Slight Clipping issues
Hard to see when in the middle of a horde and you're trying to cover them
No eye animations for the ones with visible eyes 
Not able to select which character you want to replace so you can't mix and match others
No Icons to match them

Conclusion:

A needed mod for the ones looking for a full replacement team with working arms, nice quality as well. You well need to get readjusted to your team so you dont FF them, but that's easy to do.

Pros:

Finally fixes the guess the HP game that was a constant issue in expert

Cons:

none

Conclusion:

A needed mod for anyone who plays the game seriously. 

Pros:

Makes the weapon feel alot better, aside from one issue
Makes you want to keep flipping inbetween items to listen to that lovely Click and animation on weapon choice
Reloading is alot better, though the arm goes pretty far out, it looks alot more fluid and better than the Original

Cons:

Firing/Recoil animation doesn't appear to be powerful, though I do enjoy the firing animation as is, perhaps consider making a 2 type version, one with more of a visual recoil to match the actual recoil of the gun firing and the other how it is now.

Conclusion:

Best Gun in L4D2 gets a remake for its animation that it deserves, get it.
