Pros:

- Changes majority of sounds

- Certain weapons have a more desired "kick" to them (I.e. Combat shotgun, or more commonly known as Spas, Silenced SMG, SCAR or Rifle_desert,

Cons:

- Pistols don't sound too well, however that is excused. The rest is not.

- Certain weapons have been deprived of their "kick", otherwise deafened. (I.e. Pump shotgun/Chrome Shotgun, SMG, Tactical Shotgun or The Benelli, Rifle or M16, Hunting rifle)

- AK47 Doesn't seem to have changed whatsoever?

- No grenade launcher sound change? WHAT?! >:( Blasphemy.

- The Military sniper sounds unchanged, and still weak as ever. You may be shooting it but it doesn't feel satisfying whatsoever.

Conclusion:

Let me start this off by saying that this review is based off the below video, I have not downloaded nor tested this addon in any form, and so have not had the chance to detect warping or audio glitches.    

Overall, it does what it is meant to do, that is to replace the majority of the weapons in l4d2's sounds. It did this. I'm judging the overall quality to my tastes, and I will say that although some of the sounds are detrimental to it, and don't give the user, or in this case, me, satisfaction wielding. Regardless, there are some specks of hope for not all of the sounds are horrid or depriving. Look around for more resources to pull from, keep swapping sounds to see what makes the user WANT to use that gun because it sounds kick ass, and continue to do that to every weapon. This pack has potential, but currently, needs work. 

Good day ~ Ted

Pros:

Overall beautiful execution

- Mod developers usually get back what they put into a mod, this is evident here.

- Not too bulky, nor put together poorly.

- Animations are doing the weapon justice.

Cons:

- To be perfectly honest, I experienced no drawbacks in using this add-on.

Conclusion:

Overall, I like this mod. It serves not only it purpose, but it serves it's purpose well. It is a ripe replacement for the hackneyed desert eagle. It recieves a 9.5 not because I am dissatisfied with it in any way, but because this, along with most projects, will always have room for improvement, and are never truly finished.

Pros:

-Better then vanilla bat

-Packaged well

Cons:

-Nothing fancy, but that's more aesthetics anyways

Conclusion:

Not a bad change from vanilla, but not something entirely amazing on it's own, regardless, thanks for at least putting the option out there.

Pros:

Well done skin

Custom sounds

Makes me want to actually use the m16 for once.

Cons:

Sound issues (practically overpowers other sounds, making them impossible to hear)

The Douille. (Sound a freshly ejected shell makes when it hits the ground)

Conclusion:

Very nice add-on, detailed, and honestly preferred over the vanilla m16 any day, the custom sounds are a bit of a nice touch as well, with the only problems being the mute effect along with it, and the Douille. 

Pros:

-Custom Music
-Scenic view from start to finish
-Good Frame rate from start to finish
-Bots have basic navigation
-Good use of bot dialogue
-Constant flow, no overkill'd surprises, no unsatisfying moments

Cons:

-Too many zombies at the finale, they took the life of their creator :3

-Bots had basic navigation, but lacked the ability to climb the ladders at the finale, making them a liability, but expected

-Zombies popped up in the fields out of nowhere, perhaps have them spawn behind the survivors, in the towers?

Conclusion:

Very good map, it was scenic, it had traditional music involving the player in their environment, had good frame rate from start to finish, and I think this map is worth playing and keeping. It paid homage to China without feeling like you bought one of those knock off dolls just to say it's from China. Keep up the good work man.

Only cons to this map were, like before, navigation, and the Director. The last con was just for aesthetics.
